Recognition and management of critical illness by midwives: implications for service provision

JOURNAL OF NURSING MANAGEMENT, Issue 3 2007
ENB 100, PGDipHE, SUZANNE BENCH RGN
Aim, The aim of this study was to explore midwives' recognition and management of critical illness in obstetric women in order to inform service provision. Background, Critical illness is not confined to Intensive Care. Limited published work was located examining factors affecting critical care provision by midwives. Methods, A multi-method design incorporating a paper and pencil simulation (n = 11) and in-depth interviewing (n = 5) was conducted with midwives from a large London National Health Service Trust. This study details and discusses the findings. Results, Findings indicated that frequency and type of critical illness experience impact upon midwives' critical care knowledge and skills. Midwives, especially those who were more junior, expressed anxiety regarding this aspect of practice, and considered the support of senior midwives, medical and nursing staff as crucial to effective client management. Conclusion, This study has yielded important insights into midwives' management of critical illness. Possible mechanisms to enhance the quality of service provision, and midwife support in this area are highlighted. [source]


Cardiac Output Technologies with Special Reference to the Horse

JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 3 2003
Kevin T.T. Corley
Critical illness, anesthesia, primary cardiovascular disease, and exercise may result in marked hemodynamic alterations. Measuring cardiac output (CO) is central to defining these alterations for both clinician and researcher. In the past 10 years, several new methods of measuring CO have been developed for the human medical market. Some of these methods are now validated in the horse and are in clinical use. The Fick method has been used in equine research for more than a century. It depends on simultaneous measurement of mixed venous (pulmonary arterial) and peripheral arterial oxygen content and oxygen uptake by the lungs. The technique is technically demanding, which restricts its clinical use. Indicator dilution techniques, with indocyanine green, cold (thermodilution), or lithium as the marker, have also been widely used in the horse. The indocyanine technique is cumbersome, and thermodilution requires right heart catheterization, which is not a benign procedure, making both of these methods less than ideal for clinical use. Lithium dilution requires catheterization of a peripheral artery and a jugular vein. It has recently been validated in anesthetized adult horses and neonatal foals. Doppler echocardiography is a noninvasive ultrasound-based technique. More accurate measurements are obtained with transesophageal than with transthoracic measurements; however, both methods require considerable technical expertise. Bioimpedance and pulse contour analysis are 2 new methods that have yet to be validated in the horse. With the currently available technology, lithium dilution appears to be the method of measuring CO best suited to the equine clinic. [source]


Neuromuscular manifestations of critical illness,

MUSCLE AND NERVE, Issue 2 2005
Charles F. Bolton MD
Abstract Critical illness, more precisely defined as the systemic inflammatory response syndrome (SIRS), occurs in 20%,50% of patients who have been on mechanical ventilation for more than 1 week in an intensive care unit. Critical illness polyneuropathy (CIP) and myopathy (CIM), singly or in combination, occur commonly in these patients and present as limb weakness and difficulty in weaning from the ventilator. Critical illness myopathy can be subdivided into thick-filament (myosin) loss, cachectic myopathy, acute rhabdomyolysis, and acute necrotizing myopathy of intensive care. SIRS is the predominant underlying factor in CIP and is likely a factor in CIM even though the effects of neuromuscular blocking agents and steroids predominate in CIM. Identification and characterization of the polyneuropathy and myopathy depend upon neurological examination, electrophysiological studies, measurement of serum creatine kinase, and, if features suggest a myopathy, muscle biopsy. The information is valuable in deciding treatment and prognosis. Muscle Nerve, 2005 [source]


Developing and setting up a patient and relatives intensive care support group

NURSING IN CRITICAL CARE, Issue 1 2009
Maureen Peskett
Abstract Aim:, The purpose of this article was to highlight the need to provide support for patients and relatives following critical illness and discharge from hospital and how this can be improved through the establishment of user support groups. Background:, Critical illness predisposes patients to extended physical and psychological ill health with the potential for a reduced quality of life. The authors' personal experience, patient feedback and current literature suggested that there was a need for further support during their recovery. Methods:, Building on an existing formal follow-up service, Intensive Care Unit (ICU) Support Team for Ex-Patients established a patient-centred forum, where patients and relatives could share experiences with others who had also been through critical illness by holding drop-in sessions. Feedback from those attending these flexible and informal sessions indicates that support was needed and that patients and families have found benefit in sharing experiences with others who can empathise, having been through critical illness themselves. Conclusions:, Our experience has shown there is a need that can be met simply with minimal investment of time and funding but that addresses a gap in patient support that otherwise goes unmet. Although this was a service development in one local area, it could be adapted to ICU patients and relatives more widely. [source]


Transformations of self: a phenomenological investigation into the lived experience of survivors of critical illness

NURSING IN CRITICAL CARE, Issue 1 2003
Elizabeth DE Papathanassoglou
Summary ,Based on the hermeneutical, phenomenological perspective, this study explored the lived experience of individuals with a past ­hospitalization in an intensive care unit, with focus on their dreams. The purpose was to explore how it is to have been critically ill ,Dreams are the language of the unconscious and can symbolically convey meanings ,Eight participants recounted their experiences with critical illness through semi-structured phenomenological interviews and dream-telling. An interplay between the ,factual,external' world and the ,internal' world appeared to be the basis of their perception of the situation. Participants' narratives were immensely rich in symbols of transformation, transcendence and rebirth. Transformations in perception, in lived-body, and in lived time and space were some of the themes emerging as part of both conscious and dreaming experiences. Attitudes towards death were altered, and elements of heightened spirituality were evident in the aftermath of critical illness ,Critical illness was conceptualized as a ,cocooning phase' leading to transformation of self, spiritual arousal and personal growth. Nurses may be able to alleviate suffering by supporting this process while in the ICU, as well as after discharge [source]


Emergency management of the morbidly obese

EMERGENCY MEDICINE AUSTRALASIA, Issue 4 2004
Peter Grant
Abstract Objectives: To identify the difficulties encountered with the emergency management of morbidly obese patients and formulate recommendations to streamline care. Methods: An English language literature search was undertaken using Medline (1966,2003) with key words ,morbid obesity',anaesthesia',imaging',obesity',emergency',transportation',retrieval',critical illness' and ,monitoring'. Potential articles were selected for content applicable to emergency medicine based on title and abstract and reviewed in detail. Reference lists were manually searched for further relevant articles. In view of the very limited systematic study in this area, all information deemed by the authors' to be of assistance to the emergency physician was included regardless of evidence level. Additional information was sought from standard critical care textbooks and their bibliographies and through personal communication with local ambulance and retrieval services. The authors' unpublished personal experience in providing emergency care to the morbidly obese was included for aspects of management not documented in medical literature. Results: Obesity levels and associated health problems are rapidly rising in Australia. Few studies were identified dealing with critical illness in the morbidly obese and none specifically addressing ED management. Problems identified included size related logistical issues, and limitations of physical assessment, monitoring and routine investigations. Invasive procedures, intubation and ventilation can be particularly problematic, and modified techniques may be required. Limited data indicates a poorer outcome from critical illness most marked in the case of blunt traumatic injury. Conclusion: Very obese patients present a variety of logistical and medical challenges for EDs. A series of recommendations are made based on available data. Further studies in this area would be desirable to more specifically address ED issues. [source]


Elevated sweat sodium associated with pulmonary oedema in meningococcal sepsis

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 8 2004
M. Eisenhut
Abstract Background, We observed a temporary positive sweat test with sodium and chloride levels greater than 60 mmol L,1 following meningococcal septicaemia. Objective was to investigate whether this finding is reproducible and whether this disturbance in epithelial sodium transport is related to sepsis-induced pulmonary oedema. Materials and methods, Twenty-four children with a diagnosis of meningococcal septicaemia and 10 controls with noninfectious critical illness admitted to the Royal Liverpool Children's Hospital were included. Sweat collection was by pilocarpine iontophoresis in the acute phase of the illness (days 1,5) and on follow up. Sodium and chloride concentrations were determined by flame photometry. Results, In patients with meningococcal septicaemia, sweat sodium and chloride concentrations were significantly higher in the acute compared with the recovery phase, with a mean (SD) of 31·0 (14·6) mmol L,1 in the acute vs. 19·6 (10·2) mmol L,1 on recovery for sodium and 21·0 (12·1) mmol L,1 in the acute vs. 11·8 (4·9) mmol L,1 on recovery for chloride (P < 0·01, t -test, for sodium and chloride). Sweat sodium and chloride were significantly higher in patients with meningococcal disease compared with controls and in the acute phase in patients with septicaemia-related pulmonary oedema [mean (SD) sodium: 41·0 (15·4) mmol L,1 and chloride: 28·8 (14·3) mmol L,1] compared with septic patients without [mean (SD) sodium: 24·5 (10·1) mmol L,1 and chloride: 15·3 (7·9) mmol L,1] (P < 0·01 for sodium and chloride). Conclusions, This is the first study to provide in vivo evidence of reduced epithelial sodium transport in children with septicaemia and of its association with pulmonary oedema. [source]


Exocrine pancreatic dysfunction in sepsis

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 3 2003
B. Tribl
Abstract Background Sepsis in critical illness is associated with the progressive failure of multiple organs. This study aims to establish a correlation between the severity of sepsis and exocrine pancreatic dysfunction. Materials and methods In a prospective cohort study pancreatic exocrine function was tested by means of a secretin-cholecystokinin test in 21 critically ill, mechanically ventilated patients with sepsis according to criteria of the American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference Committee (ACCP/SCCM): 11 patients with shock and 10 patients without shock. Data were compared with seven healthy controls. Results The volume of duodenal fluid was not statistically different in the three groups. Sepsis patients without shock had significantly reduced content of amylase and chymotrypsin in duodenal juice compared with healthy controls (P < 0·01). Secretion of amylase, chymotrypsin, trypsin (P < 0·01 each) and bicarbonate in duodenal fluid (P < 0·05) was impaired in the septic shock patients when compared with the healthy controls. The content of trypsin was different between sepsis patients and septic shock patients (P < 0·05). Spearman correlation analysis was significant between the amylase secretion and the APACHE III and SOFA scores (P < 0·01). The SOFA score was also related to secretion of trypsin (P < 0·05). In patients on pressor therapy, use of norepinephrine was associated with a significant decrease in bicarbonate secretion (P < 0·05). Conclusions Sepsis is associated with secretory pancreatic dysfunction that is worse in septic shock than in sepsis without shock. Impaired exocrine function was significantly correlated to the APACHE III and SOFA scores. [source]


Survival to discharge among patients treated with CRRT

HEMODIALYSIS INTERNATIONAL, Issue 1 2005
R. Wald
Continuous renal replacement therapy (CRRT) is widely used in critically ill patients with acute renal failure (ARF). The survival of patients who require CRRT and the factors predicting their outcomes are not well defined. We sought to identify clinical features to predict survival in patients treated with CRRT. We reviewed the charts of all patients who received CRRT at the Toronto General Hospital during the year 2002. Our cohort (n = 85) represented 97% of patients treated with this modality in 3 critical care units. We identified demographic variables, underlying diagnoses, transplantation status, location (medical-surgical, coronary or cardiovascular surgery intensive care units), CRRT duration, baseline creatinine clearance (CrCl), and presence of oliguria (<400 ml/d) on the day of CRRT initiation. The principal outcome was survival to hospital discharge. Among those alive at discharge, we assessed whether there was an ongoing need for renal replacement therapy. Greater than one-third (38%, 32/85) of patients survived to hospital discharge. Three (9%) of the survivors remained dialysis-dependent at the time of discharge. Survivors were younger than non-survivors (mean age 56 vs 60 y.), were on CRRT for a shorter duration (7 vs 13 d.), and had a higher baseline CrCl (79 vs 68 ml/min). Patient survival varied among different critical care units (medical surgical 33%, coronary 38%, and cardiovascular surgery 45%). Multivariable logistic regression revealed that shorter duration of CRRT, non-oliguria, and baseline CrCl > 60 ml/min were independently associated with survival to hospital discharge (p < 0.05). Critically ill patients with ARF who require CRRT continue to have high in-hospital mortality. A shorter period of CRRT dependence, non-oliguria, and higher baseline renal function may predict a more favorable prognosis. The majority of CRRT patients who survive their critical illness are independent from dialysis at the time of hospital discharge. [source]


The systemic inflammatory response syndrome in acute liver failure

HEPATOLOGY, Issue 4 2000
Nancy Rolando
The systemic inflammatory response syndrome (SIRS) in acute liver failure (ALF), in which infection is common, has not been studied. In this study, SIRS components were recorded on admission and during episodes of infection, in 887 ALF patients admitted to a single center during an 11-year period. Overall, 504 (56.8%) patients manifested a SIRS during their illness, with a maximum of 1, 2, and 3 concurrent SIRS components in 166, 238, and 100 patients, respectively. In 353 (39.8%) patients who did not become infected, a SIRS on admission was associated with a more critical illness, subsequent worsening of encephalopathy, and death. Infected patients more often developed a SIRS and one of greater magnitude. The magnitude of the SIRS in 273 patients with bacterial infection correlated with mortality, being 16.7%, 28.4%, 41.2%, and 64.7% in patients with 0, 1, 2, and 3 maximum concurrent SIRS components, respectively. Similar correlations with mortality were seen for SIRS associated with fungal infection, bacteremia, and bacterial chest infection. Fifty-nine percent of patients with severe sepsis died, as did 98% of those with septic shock. A significant association was found between progressive encephalopathy and infection. Infected patients with progressive encephalopathy manifested more SIRS components than other infected patients. For patients with a SIRS, the proportions of infected and noninfected patients manifesting worsening encephalopathy were similar. In ALF, the SIRS, whether or not precipitated by infection, appears to be implicated in the progression of encephalopathy, reducing the chances of transplantation and conferring a poorer prognosis.

Long-term effect of the ICU-diary concept on quality of life after critical illness

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010
C. G. BÄCKMAN
Background: Critically ill patients often spend time in the intensive care unit (ICU) either unconscious or sedated. On recovery, they are often in a state of confusion with memory loss that may be associated with a longstanding reduction in health-related quality of life (QoL). We hypothesised that the ICU-diary concept could improve their QoL by filling in their memory gaps. Methods: A non-randomised, prospective study in a non-academic eight-bedded general ICU. A group of patients (n=38) were selected to receive the ICU-diary concept (keeping a diary with photos while on the ICU plus a follow-up meeting) when a long and complicated course was expected. Health-related QoL at 6, 12, 24 and 36 months was compared with a group that did not receive the ICU-diary (n=224). The Medical Outcomes Study 36-Item Short-Form (SF-36) was used to measure health-related QoL. Multiple regression models adjusted for age, sex, illness severity, pre-existing disease and diagnostic category was used to analyse the effects of the ICU-diary concept at 6 months, and changes over time were analysed using repeated measures MANOVA. Results: Crude and adjusted scores for two dimensions of SF-36 (general health and vitality) and the physical component summary score were significantly higher at 6 months in the ICU-diary group (P<0.05) and some of the effects remained during the 3-year follow-up period (P<0.05). Conclusion: The ICU-diary concept was associated with improved health-related QoL during the 3-year follow-up period after a critical illness. The effect of this intervention needs to be confirmed in a larger randomised study. [source]


Application of surrogate indicators of insulin sensitivity to critically ill cats

JOURNAL OF ANIMAL PHYSIOLOGY AND NUTRITION, Issue 11-12 2005
D. L. Chan
Hyperglycaemia associated with critical illness is a common finding in non-diabetic human patients and has important implications for nutritional support. The aetiology of the hyperglycaemia is multi-factorial but believed to involve alterations in hormones regulating glucose metabolism and the development of insulin resistance. We have previously demonstrated that hyperglycaemia in critically cats similarly involves alterations in circulating concentrations of insulin, glucagon, and cortisol. Namely, with critical illness cats had hypoinsulinaemia, hyperglucagonaemia, and hypercortisolaemia. However, direct determinations of insulin sensitivity in critically ill cats have remained untested due to the complexity of calculations and frequent blood sampling required. Such techniques have, therefore, been limited to experimental models. In the interest of studying insulin sensitivity in clinical cases, surrogate indicators of insulin sensitivity, e.g, Homeostasis Model Assessment (HOMA), and Quantitative Insulin Check Index (QUICKI), have been recently applied to cats and shown to correlate to more traditional insulin sensitivity testing. HOMA is calculated ([insulin]x[(glucose)/22.5]), while QUICKI is (1/ [log insulin + log glucose]). The goal of this study was to apply the HOMA and QUICKI indices to hyperglycaemic critically ill cats and compare them to those of euglycaemic critically ill cats and controls. Twenty-six critically ill, and 21 healthy control cats were evaluated. Groups were matched for age, weight, and body condition. Of the critically ill cats, 10 were euglycaemic, and 14 were hyperglycaemic (glucose > 180 mg/dL). As compared to euglycaemic critically ill cats, HOMA was found to be significantly greater in hyperglycaemic cats [median 5.30 (range 0.90 , 25.14) vs. [2.19 (0.69 , 7.33); p = 0.016], while QUICKI was significantly lower in hyperglycaemic cats [median 0.30 mg/dl (0.25 , 0.39 mg/dl) vs. [0.34 mg/dl (0.29 , 0.38 mg/dl); p = 0.039]. Higher HOMA and lower QUICKI indices are consistent with an insulin resistant state. However, HOMA and QUICKI were not significantly different between hyperglycaemic and control cats. While the application of these indices may prove useful in determining insulin sensitivity in critically ill cats, future studies are needed to resolve discrepancies demonstrate in the current study.

Patients' recovery after critical illness at early follow-up

JOURNAL OF CLINICAL NURSING, Issue 5-6 2010
Michelle A Kelly
Aim., To determine the quality of life, particularly physical function, of intensive care survivors during the early recovery process. Background., Survivors of critical illness face ongoing challenges after discharge from the intensive care unit and on returning home. Knowledge about health issues during early phases of recovery after hospital discharge is emerging, yet still limited. Design., Descriptive study where the former critically ill patients completed instruments on general health and quality of life (SF-36) in the first six months of recovery. Methods., Participants responded to the SF-36 questionnaire and questions about problems, one to six months after intensive care, either face-to-face or by telephone. Results., Thirty-nine participants had a mean age of 60 years; of them, 59% were men and had been in intensive care for 1,69 days (median = 5). Most participants (69%) rated their health as good or fair, but 54% rated general health as worse than a year ago. Mean quality of life scores for all scales ranged from 25,65·5%, with particularly low scores for Role-Physical (25) and Pain (45·1). Half the participants reported difficulty with mobility, sleep and concentration, and 72% that their responsibilities at home had changed. No relationships were found between SF-36 scores and admission diagnosis, gender, age or length of intensive care stay. Conclusions., These survivors of critical illness and hospitalisation in an intensive care unit perceive their general health to be good despite experiencing significant physical limitations and disturbed sleep during recovery. Relevance to clinical practice., Knowledge of issues in these early phases of recovery and discussion and resolution of patient problems could normalise the experience for the patient and help to facilitate better quality of life.

An integrative review and meta-synthesis of the scope and impact of intensive care liaison and outreach services

JOURNAL OF CLINICAL NURSING, Issue 23 2009
Ruth Endacott
Aim., To determine activities and outcomes of intensive care unit Liaison Nurse/Outreach services. The review comprised two stages: (1) integrative review of qualitative and quantitative studies examining intensive care liaison/outreach services in the UK and Australia and (2) meta-synthesis using the Nursing Role Effectiveness Model as an a priori model. Background., Acute ward patients are at risk of adverse events and patients recovering from critical illness are vulnerable to deterioration. Proactive and reactive strategies have been implemented to facilitate timely identification of patients at risk. Design., Systematic review. Methods., A range of data bases was searched from 2000,2008. Studies were eligible for review if they included adults in any setting where intensive care unit Liaison Nurse or Outreach services were provided. From 1423 citations and 65 abstracts, 20 studies met the inclusion criteria. Results., Intensive care liaison/outreach services had a beneficial impact on intensive care mortality, hospital mortality, unplanned intensive care admissions/re-admissions, discharge delay and rates of adverse events. A range of research methods were used; however, it was not possible to conclude unequivocally that the intensive care liaison/outreach service had resulted in improved outcomes. The major unmeasured benefit across all studies was improved communication pathways between critical care and ward staff. Outcomes for nurses in the form of improved confidence, knowledge and critical care skills were identified in qualitative studies but not measured. Conclusion., The varied nature of the intensive care liaison/outreach services reviewed in these studies suggests that they should be treated as bundled interventions, delivering a treatment package of care. Further studies should examine the impact of critical care support on the confidence and skills of ward nurses. Relevance to clinical practice., Advanced nursing roles can improve outcomes for patients who are vulnerable to deterioration. The Nursing Role Effectiveness Model provides a useful framework for evaluating the impact of these roles. [source]


Factual memories of ICU: recall at two years post-discharge and comparison with delirium status during ICU admission , a multicentre cohort study

JOURNAL OF CLINICAL NURSING, Issue 9 2007
Brigit L Roberts RN, IC Cert
Aims and objective., To examine the relationship between observed delirium in ICU and patients' recall of factual events up to two years after discharge. Background., People, the environment, and procedures are frequently cited memories of actual events encountered in ICU. These are often perceived as stressors to the patients and the presence of several such stressors has been associated with the development of reduced health-related quality of life or post-traumatic stress syndrome. Design., Prospective cohort study using interview technique. Method., The cohort was assembled from 152 patients who participated in a previously conducted multi-centre study of delirium incidence in Australian ICUs. The interviews involved a mixture of closed- and open-ended questions. Qualitative responses regarding factual memories were analysed using thematic analysis. A five-point Likert scale with answers from ,always' to ,never' was used to ask about current experiences of dream, anxiety, sleep problems, fears, irritability and/or mood swings. Scoring ranged from 6 to 30 with a mid-point value of 18 indicating a threshold value for the diagnosis of post-traumatic stress syndrome. A P -value of <0·05 was considered significant for all analyses. Results., Forty-one (40%) out of 103 potential participants consented to take part in the follow-up interview; 18 patients (44%) had been delirious and 23 patients (56%) non-delirious during the ICU admission. The non-participants (n = 62) formed a control group to ensure a representative sample; 83% (n = 34) reported factual memories either with or without recall of dreaming. Factual memories were significantly less common (66% cf. 96%) in delirious patients (OR 0·09, 95%CI 0·01,0·85, p = 0·035). Five topics emerged from the thematic analysis: ,procedures', ,staff', ,comfort', ,visitors', and ,events'. Based on the current experiences, five patients (12%, four non-delirious and one delirious) scored ,18 indicative of symptoms of post-traumatic stress syndrome; this did not reach statistical significance. Memory of transfer out of ICU was less frequent among the delirious patients (56%, n = 10) than among the non-delirious patients (87%, n = 20) (p = 0·036). Conclusion., Most patients have factual memories of their ICU stay. However, delirious patients had significantly less factual recall than non-delirious patients. Adverse psychological sequelae expressed as post-traumatic stress syndrome was uncommon in our study. Every attempt must be made to ensure that the ICU environment is as hospitable as possible to decrease the stress of critical illness. Post-ICU follow-up should include filling in the ,missing gaps', particularly for delirious patients. Ongoing explanations and a caring environment may assist the patient in making a complete recovery both physically and mentally. Relevance to clinical practice., This study highlights the need for continued patient information, re-assurance and optimized comfort. While health care professionals cannot remove the stressors of the ICU treatments, we must minimize the impact of the stay. It must be remembered that most patients are aware of their surroundings while they are in the ICU and it should, therefore, be part of ICU education to include issues regarding all aspects of patient care in this particularly vulnerable subset of patients to optimize their feelings of security, comfort and self-respect.

Signs of critical illness polyneuropathy and myopathy can be seen early in the ICU course

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2009
K. AHLBECK
Background: Critical illness polyneuropathy and myopathy (CIPNM) is recognized as a common condition that develops in the intensive care unit (ICU). It may lead to a prolonged hospital stay with subsequent increased ICU and hospital costs. Knowledge of predisposing factors is insufficient and the temporal pattern of CIPNM has not been well described earlier. This study investigated patients with critical illness in need of prolonged mechanical ventilation, describing comprehensively the time course of changes in muscle and nerve neurophysiology, histology and mitochondrial oxidative function. Methods: Ten intensive care patients were investigated 4, 14 and 28 days after the start of mechanical ventilation. Laboratory tests, neurophysiological examination, muscle biopsies and clinical examinations were performed. Neurophysiological criteria for CIPNM were noted and measurements for mitochondrial content, mitochondrial respiratory enzymes and markers of oxidative stress were performed. Results: While all patients showed pathologic changes in neurophysiologic measurements, only patients with sepsis and steroid treatment (5/5) fulfilled the CIPNM criteria. The presence of CIPNM did not affect the outcome, and the temporal pattern of CIPNM was not uniform. All CIP changes occurred early in ICU care, while myopathy changes appeared somewhat later. Citrate synthase was decreased between days 4 and 14, and mitochondrial superoxide dismutase was increased. Conclusion: With comprehensive examination over time, signs of CIPNM can be seen early in ICU course, and appear more likely to occur in patients with sepsis and corticosteroid treatment. [source]

Opioids and opiates: analgesia with cardiovascular, haemodynamic and immune implications in critical illness

JOURNAL OF INTERNAL MEDICINE, Issue 2 2006
P. E. MOLINA
Abstract. Traumatic injury, surgical interventions and sepsis are amongst some of the clinical conditions that result in marked activation of neuroendocrine and opiate responses aimed at restoring haemodynamic and metabolic homeostasis. The central activation of the neuroendocrine and opiate systems, known collectively as the stress response, is elicited by diverse physical stressor conditions, including ischaemia, glucopenia and inflammation. The role of the hypothalamic,pituitary,adrenal axis and sympathetic nervous system in counterregulation of haemodynamic and metabolic alterations has been studied extensively. However, that of the endogenous opiates/opioid system is still unclear. In addition to activation of the opiate receptor through the endogenous release of opioids, pharmacotherapy with opiate receptor agonists is frequently used for sedation and analgesia of injured, septic and critically ill patients. How this affects the haemodynamic, cardiovascular, metabolic and immune responses is poorly understood. The variety of opiate receptor types, their specificity and ubiquitous location both in the central nervous system and in the periphery adds additional complicating factors to the clear understanding of their contribution to the stress response to the various physical perturbations. This review aims at discussing scientific evidence gathered from preclinical studies on the role of endogenous opioids as well as those administered as pharmacological agents on the host cardiovascular, neuroendocrine, metabolic and immune response mechanisms critical for survival from injury in perspective with clinical observations that provide parallel assessment of relevant outcome measures. When possible, the clinical relevance and corresponding scenarios where this evidence can be integrated into our understanding of the clinical implications of opiate effects will be examined. Overall, the scientific basis to enhance clinical judgment and expectations when using opioid sedation and analgesia in the management of the injured, septic or postsurgical patient will be discussed.

Recognition and management of critical illness by midwives: implications for service provision

JOURNAL OF NURSING MANAGEMENT, Issue 3 2007
ENB 100, PGDipHE, SUZANNE BENCH RGN
Aim, The aim of this study was to explore midwives' recognition and management of critical illness in obstetric women in order to inform service provision. Background, Critical illness is not confined to Intensive Care. Limited published work was located examining factors affecting critical care provision by midwives. Methods, A multi-method design incorporating a paper and pencil simulation (n = 11) and in-depth interviewing (n = 5) was conducted with midwives from a large London National Health Service Trust. This study details and discusses the findings. Results, Findings indicated that frequency and type of critical illness experience impact upon midwives' critical care knowledge and skills. Midwives, especially those who were more junior, expressed anxiety regarding this aspect of practice, and considered the support of senior midwives, medical and nursing staff as crucial to effective client management. Conclusion, This study has yielded important insights into midwives' management of critical illness. Possible mechanisms to enhance the quality of service provision, and midwife support in this area are highlighted. [source]


Neurodevelopmental outcomes and surgery in neonates

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 12 2006
Karen Walker
Abstract: A neonate requiring major surgery in 2006 has a greater prospect of survival than ever before. Increasingly, however, there is awareness that critical illness may affect later neurodevelopment. Pre-existing conditions in addition to the physiologic stresses associated with cardiac and general surgery are implicated but remain unavoidable in the case of significant structural abnormalities such as transposition of the great arteries or congenital diaphragmatic hernia. For those affected by neurodevelopmental impairment, there is a significant cost to the child, family and society. Current research focuses on the preventable causes of brain injury, before, during and after the intervention, and the rate of impairment in apparently uncomplicated procedures. In contrast to the quantity of neurodevelopmental outcome data following cardiac surgery, there remain few outcome studies dealing with non-cardiac surgery despite such intervention being two to three times more common. There appear to be compelling clinical and economic arguments for the instigation of formalised population-based developmental assessments for all infants undergoing major surgery. [source]

Incidence and Clinical Relevance of Hyperglycemia in Critically Ill Dogs

JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 5 2007
Danna M. Torre
Background: Hyperglycemia associated with critical illness in nondiabetic human patients is a common occurrence in the intensive care unit (ICU), with a reported incidence as high as 71%. Hypothesis: Hyperglycemia in critically ill dogs increases the risk of morbidity and mortality. Animals: Two hundred forty-five dogs hospitalized in the ICU over a 2-month period were evaluated. Methods: Prospective observational study was conducted over a 2-month period. All dogs in the ICU had their highest daily blood glucose concentration recorded. All dogs with diabetes were excluded from the study. Hyperglycemia was defined as a blood glucose concentration >120 mg/dL. Dogs with hyperglycemia were monitored for persistence and resolution of hyperglycemia. Results: During the study period, 245 dogs were evaluated, of which 38 (16%) were hyperglycemic. Twenty-six percent (10/ 38) developed hyperglycemia during hospitalization, whereas 74% (28/38) were hyperglycemic at presentation. Length of hospitalization (LOH) was shorter in dogs that presented with hyperglycemia compared with those that developed hyperglycemia during hospitalization (P= .001). Seventy-one percent (27/38) of dogs were discharged from the hospital, whereas the remaining 29% (11/38) died or were euthanatized. Nonsurvivors had significantly higher median glucose concentration (median, 176 mg/dL; range 122,310 mg/dL) than did survivors (median, 139 mg/dL; 121,191 mg/dL; P= .021). Conclusions and Clinical Importance: The incidence of hyperglycemia in this population of dogs was 16%. Dogs that developed hyperglycemia had longer LOH and nonsurvivors had more pronounced hyperglycemia than did survivors. [source]


Neuromuscular manifestations of critical illness,

MUSCLE AND NERVE, Issue 2 2005
Charles F. Bolton MD
Abstract Critical illness, more precisely defined as the systemic inflammatory response syndrome (SIRS), occurs in 20%,50% of patients who have been on mechanical ventilation for more than 1 week in an intensive care unit. Critical illness polyneuropathy (CIP) and myopathy (CIM), singly or in combination, occur commonly in these patients and present as limb weakness and difficulty in weaning from the ventilator. Critical illness myopathy can be subdivided into thick-filament (myosin) loss, cachectic myopathy, acute rhabdomyolysis, and acute necrotizing myopathy of intensive care. SIRS is the predominant underlying factor in CIP and is likely a factor in CIM even though the effects of neuromuscular blocking agents and steroids predominate in CIM. Identification and characterization of the polyneuropathy and myopathy depend upon neurological examination, electrophysiological studies, measurement of serum creatine kinase, and, if features suggest a myopathy, muscle biopsy. The information is valuable in deciding treatment and prognosis. Muscle Nerve, 2005 [source]


Recovering from the psychological impact of intensive care: how constructing a story helps

NURSING IN CRITICAL CARE, Issue 6 2009
Susan Lecky Williams
ABSTRACT Background: Numerous studies have demonstrated both the risk of post-traumatic stress as a result of intensive care unit (ICU) treatment and the efficacy of successful narrative processing for recovery from psychological trauma. Aim: This article is based on recent doctoral research exploring the impact of unanticipated life threats after admission to hospital. It examines the difficulties ICU patients have with constructing coherent narratives of their illness experience and the significance of those difficulties for psychological recovery from critical illness. Methods: The original research used a qualitative design blending discourse, narrative, and phenomenological approaches guided by hermeneutical sensitivity to the evolving language of narrative processing. Patients chosen from ICU discharge summaries showing a critical life-threatening event after admission to hospital were interviewed soon after discharge from hospital and then again 1 year later. Unstructured interviews explored participant experience of a critical event and its aftermath. Results: This article focuses in particular on one finding from the doctoral research. Unanticipated critical illness presented some patients with difficulties in accomplishing the fundamental human task of constructing a narrative of their experience. Risk factors were observed identifying specific vulnerabilities. The extent to which difficulties were overcome impacted positively on the patient's sense of well-being 1 year after discharge. Conclusions: In order to recover psychologically, some ICU patients need help overcoming obstacles to their ability to construct an adequately coherent narrative of their experience. Relevance to clinical practice: ICU follow-up clinics could gain increased clarity of purpose from this narrative conceptual framework, eventually evaluating and validating benchmarks for assessing psychological recovery in relation to specified dimensions of narrative processing. Practice development informed by narrative process theory could also enhance ICU nursing communication. Since story construction is central to a person's core identity processes, person-centred nursing would also be implicated. [source]


Developing and setting up a patient and relatives intensive care support group

NURSING IN CRITICAL CARE, Issue 1 2009
Maureen Peskett
Abstract Aim:, The purpose of this article was to highlight the need to provide support for patients and relatives following critical illness and discharge from hospital and how this can be improved through the establishment of user support groups. Background:, Critical illness predisposes patients to extended physical and psychological ill health with the potential for a reduced quality of life. The authors' personal experience, patient feedback and current literature suggested that there was a need for further support during their recovery. Methods:, Building on an existing formal follow-up service, Intensive Care Unit (ICU) Support Team for Ex-Patients established a patient-centred forum, where patients and relatives could share experiences with others who had also been through critical illness by holding drop-in sessions. Feedback from those attending these flexible and informal sessions indicates that support was needed and that patients and families have found benefit in sharing experiences with others who can empathise, having been through critical illness themselves. Conclusions:, Our experience has shown there is a need that can be met simply with minimal investment of time and funding but that addresses a gap in patient support that otherwise goes unmet. Although this was a service development in one local area, it could be adapted to ICU patients and relatives more widely. [source]


Transformations of self: a phenomenological investigation into the lived experience of survivors of critical illness

NURSING IN CRITICAL CARE, Issue 1 2003
Elizabeth DE Papathanassoglou
Summary ,Based on the hermeneutical, phenomenological perspective, this study explored the lived experience of individuals with a past ­hospitalization in an intensive care unit, with focus on their dreams. The purpose was to explore how it is to have been critically ill ,Dreams are the language of the unconscious and can symbolically convey meanings ,Eight participants recounted their experiences with critical illness through semi-structured phenomenological interviews and dream-telling. An interplay between the ,factual,external' world and the ,internal' world appeared to be the basis of their perception of the situation. Participants' narratives were immensely rich in symbols of transformation, transcendence and rebirth. Transformations in perception, in lived-body, and in lived time and space were some of the themes emerging as part of both conscious and dreaming experiences. Attitudes towards death were altered, and elements of heightened spirituality were evident in the aftermath of critical illness ,Critical illness was conceptualized as a ,cocooning phase' leading to transformation of self, spiritual arousal and personal growth. Nurses may be able to alleviate suffering by supporting this process while in the ICU, as well as after discharge [source]


Patient involvement in health-related decisions during prolonged critical illness,

RESEARCH IN NURSING & HEALTH, Issue 4 2007
Mary Beth Happ
Abstract We describe patterns of communication of patients involved in health-related decision making during prolonged mechanical ventilation (PMV). Data were collected using observation, interview, and record review. Twelve of 30 patients participated in decisions about initiating, withdrawing, and withholding life-sustaining treatment, surgery, artificial feeding, financial/legal issues, discharge care, and daily care procedures. Patient involvement was largely validation or confirmation of what clinicians and families had already decided. Patients' participation was enlisted by clinicians and family members even when the patients did not exhibit full decisional capacity. Patient involvement in health-related decisions during prolonged critical illness is a shared and negotiated process that requires continued empirical study and ethical analysis. © 2007 Wiley Periodicals, Inc.

Effect of an episode of critical illness on subsequent hospitalisation: a linked data study

ANAESTHESIA, Issue 2 2010
T. A. Williams
Summary Healthcare utilisation can affect quality of life and is important in assessing the cost-effectiveness of medical interventions. A clinical database was linked to two Australian state administrative databases to assess the difference in incidence of healthcare utilisation of 19 921 patients who survived their first episode of critical illness. The number of hospital admissions and days of hospitalisation per patient-year was respectively 150% and 220% greater after than before an episode of critical illness (assessed over the same time period). This was the case regardless of age or type of surgery (i.e. cardiac vs non-cardiac). After adjusting for the ageing effect of the cohort as a whole, there was still an unexplained two to four-fold increase in hospital admissions per patient-year after an episode of critical illness. We conclude that an episode of critical illness is a robust predictor of subsequent healthcare utilisation. [source]

Emergency management of the morbidly obese

EMERGENCY MEDICINE AUSTRALASIA, Issue 4 2004
Peter Grant
Abstract Objectives: To identify the difficulties encountered with the emergency management of morbidly obese patients and formulate recommendations to streamline care. Methods: An English language literature search was undertaken using Medline (1966,2003) with key words ,morbid obesity',anaesthesia',imaging',obesity',emergency',transportation',retrieval',critical illness' and ,monitoring'. Potential articles were selected for content applicable to emergency medicine based on title and abstract and reviewed in detail. Reference lists were manually searched for further relevant articles. In view of the very limited systematic study in this area, all information deemed by the authors' to be of assistance to the emergency physician was included regardless of evidence level. Additional information was sought from standard critical care textbooks and their bibliographies and through personal communication with local ambulance and retrieval services. The authors' unpublished personal experience in providing emergency care to the morbidly obese was included for aspects of management not documented in medical literature. Results: Obesity levels and associated health problems are rapidly rising in Australia. Few studies were identified dealing with critical illness in the morbidly obese and none specifically addressing ED management. Problems identified included size related logistical issues, and limitations of physical assessment, monitoring and routine investigations. Invasive procedures, intubation and ventilation can be particularly problematic, and modified techniques may be required. Limited data indicates a poorer outcome from critical illness most marked in the case of blunt traumatic injury. Conclusion: Very obese patients present a variety of logistical and medical challenges for EDs. A series of recommendations are made based on available data. Further studies in this area would be desirable to more specifically address ED issues. [source]
