    How Would Terminally Ill Patients Have Others Make Decisions for Them in the Event of Decisional Incapacity?

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 12 2007
    A Longitudinal Study
    OBJECTIVES: To determine the role terminally ill patients would opt to have their loved ones and physicians play in healthcare decisions should they lose decision-making capacity and how this changes over time. DESIGN: Serial interviews. SETTING: The study institutions were The Johns Hopkins Medical Institutions in Baltimore, Maryland, and St. Vincent's Hospital, in New York. PARTICIPANTS: One hundred forty-seven patients with cancer, amyotrophic lateral sclerosis, or heart failure, at baseline and 3 and 6 months. RESULTS: Patients' baseline decision control preferences varied widely, but most opted for shared decision-making, leaning slightly toward independence from their loved ones. This did not change significantly at 3 or 6 months. Fifty-seven percent opted for the same degree of decision control at 3 months as at baseline. In a generalized estimating equation model adjusted for time, more-independent decision-making was associated with college education (P=.046) and being female (P=.01), whereas more-reliant decision-making was associated with age (P<.001). Patients leaned toward more reliance upon physicians to make best-interest determinations at diagnosis but opted for physicians to decide based upon their own independent wishes (substituted judgment) over time, especially if college educated. CONCLUSION: Terminally ill patients vary in how much they wish their own preferences to control decisions made on their behalf, but most would opt for shared decision-making with loved ones and physicians. Control preferences are stable over time with respect to loved ones, but as they live longer with their illnesses, patients prefer somewhat less reliance upon physicians. [source]

    Evaluation of Emergency Air Evacuation of Critically Ill Patients from Cruise Ships

    JOURNAL OF TRAVEL MEDICINE, Issue 6 2001
    Laurence D. Prina
    Background: The study objectives were to assess the ship physician's diagnostic accuracy in making the decision to air evacuate critically ill patients from cruise ships, to determine the outcome of these patients, and the overall benefit of air evacuation. Methods: From October 1999 to May 2000, we performed a prospective study of critically ill patients coming from cruise ships in the Caribbean and transported to our institution by air ambulance. Demographics, initial diagnosis, and treatment on board were collected by the triage officer at the time of the cruise physician's first call. In route complications and flight team composition were obtained from the air ambulance monitoring log. Patients were followed-up in the hospital for complications, outcome, and final diagnosis. Results: A consecutive series of 104 patients were considered for analysis. There were 65 men and 39 women (mean age: 68.7 years). Cruise physician's diagnosis was correct in more than 90% of the cases. Internal medicine and surgical conditions represented 80.8% and 19.2% of the cases respectively, falling mainly into three categories: cardiac (34.6%), neurological (20.2%), and digestive (14%). Two cardiac arrests and 1 ventricular fibrillation were successfully resuscitated and 5 of 15 myocardial infarctions received thrombolytic therapy on board. Air transfers were warranted in 96.1% of the cases and physician presence in the flight was considered appropriate in 97.6%. In route complications and mortality rate were 5.8% and 2.9% respectively, related to serious cardiac events. Among the 98 hospitalized patients, 10 patients developed new complications and 5 died. The overall mortality rate was 7.7%. Conclusion: The cruise industry appears off to a good start in the medical treatment of passengers needing air evacuation to a land based medical facility. There is room for improvement and adoption of American College of Emergency Physicians (ACEP) and International Council of Cruise Lines (ICCL) Health Care Guidelines are meaningful first steps. Analysis of Caribbean medical facilities and implementation of active telemedicine conferencing represent alternatives to air evacuation that need to be studied. [source]


    Health Care Costs of Seriously Mentally Ill Patients Enrolled in Enhanced Treatment

    Andrea M. Hegedus PhD
    Patients with psychosis (N = 866) were recruited into enhanced or standard Veterans Administration (VA) treatment. Enhanced programs, previously shown to be more effective, were less costly than VA standard care. Adjusted costs fell from $32,000,$55,000 (for the 1st year) to $20,000,$36,000 (for the 4th year). Costs were associated positively with schizophrenia, living in the Northeast region of the United States, and poorer baseline functioning. [source]


    Comparison of Sustained Hemodiafiltration With Continuous Venovenous Hemodiafiltration for the Treatment of Critically Ill Patients With Acute Kidney Injury

    ARTIFICIAL ORGANS, Issue 4 2010
    Masanori Abe
    Abstract Despite improvements in medical care, the mortality of critically ill patients with acute kidney injury (AKI) who require renal replacement therapy (RRT) remains high. We describe a new approach, sustained hemodiafiltration, to treat patients who suffered from acute kidney injury and were admitted to intensive care units (ICUs). In our study, 60 critically ill patients with AKI who required RRT were treated with either continuous venovenous hemodiafiltration (CVVHDF) or sustained hemodiafiltration (S-HDF). The former was performed by administering a postfilter replacement fluid at an effluent rate of 35 mL/kg/h, and the latter was performed by administering a postfilter replacement fluid at a dialysate-flow rate of 300,500 mL/min. The S-HDF was delivered on a daily basis. The baseline characteristics of the patients in the two treatment groups were similar. The primary study outcome,survival until discharge from the ICU or survival for 30 days, whichever was earlier,did not significantly differ between the two groups: 70% after CVVHDF and 87% after S-HDF. The hospital-survival rate after CVVHDF was 63% and that after S-HDF was 83% (P < 0.05). The number of patients who showed renal recovery at the time of discharge from the ICU and the hospital and the duration of the ICU stay significantly differed between the two treatments (P < 0.05). Although there was no significant difference between the mean number of treatments performed per patient, the mean duration of daily treatment in the S-HDF group was 6.5 ± 1.0 h, which was significantly shorter. Although the total convective volumes,the sum of the replacement-fluid and fluid-removal volumes,did not differ significantly, the dialysate-flow rate was higher in the S-HDF group. Our results suggest that in comparison with conventional continuous RRT, including high-dose CVVHDF, more intensive renal support in the form of postdilution S-HDF will decrease the mortality and accelerate renal recovery in critically ill patients with AKI.

    Unexpected Events during the Intrahospital Transport of Critically Ill Patients

    ACADEMIC EMERGENCY MEDICINE, Issue 6 2007
    Jonathan P.N. Papson MBBS
    Objectives:To examine unexpected events (UEs) that occur during the intrahospital transport of critically ill emergency department patients. Methods:This was a prospective observational study of consecutive intrahospital transports between March 2003 and June 2004. The escorting emergency physician completed the data collection document either during or immediately after the transport. This document detailed equipment-related UEs, patient instability and invasive line-related UEs, whether the UEs required intervention, and whether the UEs were potentially life threatening (serious UEs). Results:Of 339 transports observed, 230 (67.9%; 95% confidence interval [CI] = 62.6% to 72.7%) were associated with 604 UEs. Overall, there was a median of 1.0 UE per transport (range, 0,16). There were 277 (45.9%; 95% CI = 41.8% to 49.9%) UEs related to equipment, 158 (26.2%; 95% CI = 22.7% to 29.9%) related to patient instability, 156 (25.8%; 95% CI = 22.4% to 29.6%) related to equipment lines, and 13 (2.2%, 95% CI = 1.2% to 3.8%) miscellaneous UEs. The most common UEs were oxygen saturation probe failures, lead and line tangles, hypotension, and the wearing off of sedation and/or paralysis. Most UEs (478 [79.1%]; 95% CI = 75.6% to 82.3%) required an intervention. Emergency physicians had a significantly lower UE rate than residents. Thirty serious UEs occurred; 5.0% (95% CI = 3.4% to 7.1%) of UEs and 8.9% (95% CI = 6.2% to 12.5%) of transports were associated with a serious UE. The most common were severe hypotension, decreasing consciousness requiring intubation, and increased intracranial pressure. Conclusions:Unexpected events during the intrahospital transport of critically ill patients from the emergency department are common and can be potentially life threatening. Transporting physician experience is associated with UE rate. Strict adherence to and review of existing transport guidelines is recommended. [source]


    An Educator's Guide to Teaching Emergency Medicine to Medical Students

    ACADEMIC EMERGENCY MEDICINE, Issue 3 2004
    Wendy C. Coates MD
    Abstract There is a need for every medical school graduate to handle emergencies as they arise in the daily practice of medicine. Emergency medicine (EM) educators are in a unique position to provide students with basic life support skills, guidance in assessing the undifferentiated patient, and exposure to the specialty of EM during all years of medical school. Emergency physicians can become involved in a variety of education experiences that can supplement the preclinical curriculum and provide access to our specialty at an early stage. A well-designed course in the senior year allows students to develop critical thinking and patient management skills that are necessary for any medical career path. It can ensure that all medical students are exposed to the skills essential for evaluating and stabilizing the acutely ill patient. To implement this type of course, learning objectives and evaluation methods must be set when the curriculum is developed. An effective course combines didactic and clinical components that draw on the strengths of the teaching institution and faculty of the department. A structured clerkship orientation session and system for feedback to students are essential in nurturing the development of student learners. This article provides an approach to assist the medical student clerkship director in planning and implementing EM education experiences for students at all levels of training, with an emphasis on the senior-year rotation.

    Bench to Bedside: Electrophysiologic and Clinical Principles of Noninvasive Hemodynamic Monitoring Using Impedance Cardiography

    ACADEMIC EMERGENCY MEDICINE, Issue 6 2003
    Richard L. Summers MD
    Abstract The evaluation of the hemodynamic state of the severely ill patient is a common problem in emergency medicine. While conventional vital signs offer some insight into delineating the circulatory pathophysiology, it is often impossible to determine the true clinical state from an analysis of blood pressure and heart rate alone. Cardiac output measurements by thermodilution have been the criterion standard for the evaluation of hemodynamics. However, this technology is invasive, expensive, time-consuming, and impractical for most emergency department environments. Impedance cardiography (ICG) is a noninvasive method of obtaining continuous measurements of hemodynamic data such as cardiac output that requires little technical expertise. ICG technology was first developed by NASA in the 1960s and is based on the idea that the human thorax is electrically a nonhomogeneous, bulk conductor. Variation in the impedance to flow of a high-frequency, low-magnitude alternating current across the thorax results in the generation of a measured waveform from which stroke volume can be calculated by a modification of the pulse contour method. To adequately judge the possible role of this technology in the practice of emergency medicine, it is important to have a sufficient understanding of the basic scientific principles involved as well as the clinical validity and limitations of the technique.

    Aspiration syndromes: 10 clinical pearls every physician should know

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2007
    H. S. Paintal
    Summary Aspiration syndromes are clinically and pathologically classified into three sets of disorders: (i) large airway mechanical obstruction caused by foreign bodies; (ii) aspiration pneumonitis; and (iii) aspiration pneumonia. In this article, we discuss the common clinical presentations, risk factors, radiographic features and methods of management of these disorders. We highlight recent recommendations and controversies surrounding the prevention of aspiration pneumonia in the critically ill patient. Finally, we review ethical dilemmas surrounding feeding and aspiration risk concerns in debilitated and demented patients. [source]


    Venous thromboembolism in the medically ill patient: a call to action

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2005
    J.-F. Bergmann
    Summary The risk of venous thromboembolism (VTE) in medical patients is generally underestimated. However, recent studies including two large double-blind placebo-controlled trials, the Prospective Evaluation of Dalteparin Efficacy for Prevention of VTE in Immobilised Patients trial (PREVENT) and prophylaxis in MEDical patients with ENOXaparin, study show that low-molecular-weight heparins (LMWHs) provide effective thromboprophylaxis for medical patients at risk from VTE without increasing the risk of bleeding. In PREVENT the significant 45%, reduction in VTE among patients receiving dalteparin 5000 IU once daily for 14 days was attributed entirely to a reduction in clinically relevant VTE. The recently published guidelines for the prevention and treatment of VTE, issued by the American College of Chest Physicians, recommend prophylaxis with LMWHs (or low-dose unfractionated heparin) in acutely ill medical patients with risk factors for VTE (grade 1A). Current evidence should encourage the more widespread adoption of thromboprophylaxis in at-risk medical patients, and thus reduce the number of preventable deaths and complications due to VTE.

    Literature review: decision-making regarding slow resuscitation

    JOURNAL OF CLINICAL NURSING, Issue 11 2007
    H Dip, Jacinta Kelly MSc
    Aims and objectives., Applying ethical principles as a framework, a review of the literature will be presented regarding the decision-making process of slow codes. Background., Slow codes are cardiopulmonary resuscitative efforts intentionally conducted too slowly for resuscitation to occur. While some authors argue that a slow code is a non-maleficent and beneficent act towards the hopelessly ill patient, others believe that this practice is harmful and deceptive, that it disregards patient and surrogate autonomy and deprives the patient of a peaceful death. Method., Literature review. Results., Decision-making surrounding cardiopulmonary resuscitation receives considerable attention in the literature. However, data relating to the decision-making process in slow codes is sparse. One ethnographic study described the practice of slow codes as doing good and preventing harm to the patient. Conclusions., It was evident from the literature review that slow codes, even in the most limited form, are invasive and undignified and that they prolong death and suffering. Further research is needed to examine why slow codes happen despite the availability of a do-not-resuscitate order. Relevance to clinical practice., Decision-making regarding cardiopulmonary resuscitation is increasingly problematic in Ireland. The literature review suggests that clinical guidelines regarding decision-making and cardiopulmonary resuscitation should be introduced to reduce the likelihood of slow codes occurring, but also that nurses and doctors endeavour to communicate more effectively with patients and family.

    Unusual hypersensitivity to warfarin in a critically ill patient

    JOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 5 2004
    H. Konishi PhD
    Summary A patient was admitted to the intensive care unit because of respiratory failure, and warfarin therapy was started at 2 mg/day for the treatment of pulmonary embolism, together with other medications. Despite the low dosage of warfarin, international normalized ratio (INR) was markedly elevated from 1·15 to 11·28 for only 4 days, and bleeding symptoms concurrently developed. Vitamin K2 was infused along with discontinuation of warfarin. One day later, the INR was found to have decreased, and bleeding was also improved. An objective causality assessment indicated a probable relationship between clotting abnormality and warfarin administration, although the degree of elevation of the INR was unusual in the light of the daily warfarin dose and duration of its exposure. Based on the clinical status of the patient, it was suspected that several conditions contributed to the abnormal hypersensitivity to warfarin. Contributory factors probably included pharmacokinetic interactions with co-administrated drugs, vitamin K deficiency caused by decreased dietary intake, reduced gut bacterial production, impaired intestinal absorption and hepatic synthetic capacity, and increased consumption of clotting factors. In view of our experience in the present case, it should be stressed that close monitoring of coagulation capacity is necessary in critically ill patients in order to avoid fatal haemorrhage after initiating warfarin therapy regardless of the dosage.

    james j., butler-williams c., hunt j. & cox h. (2010) Journal of Nursing Management18, 548,555 Vital signs for vital people: an exploratory study into the role of the Healthcare Assistant in recognising, recording and responding to the acutely ill patient in the general ward setting Aim, To examine the contribution of the Healthcare Assistant (HCA) as the recogniser, responder and recorder of acutely ill patients within the general ward setting. Background, Concerns have been highlighted regarding the recognition and management of the acutely ill patient within the general ward setting. The contribution of the HCA role to this process has been given limited attention. Methods, A postal survey of HCAs was piloted and conducted within two district general hospitals. Open and closed questions were used. Results, Results suggest that on a regular basis HCAs are caring for acutely ill patients. Contextual issues and inaccuracies in some aspects of patient assessment were highlighted. It would appear normal communication channels and hierarchies were bypassed when patients' safety was of concern. Educational needs were identified including scenario-based learning and the importance of ensuring mandatory training is current. Conclusions and implications for nursing management, HCAs play a significant role in the detection and monitoring of acutely ill patients. Acknowledgement is needed of the contextual factors in the general ward setting which may influence the quality of this process. The educational needs identified by this study can assist managers to improve clinical supervision and educational input in order to improve the quality of care for acutely ill patients. [source]


    Nosocomial infections and antimicrobial resistance in critical care medicine

    JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 1 2006
    Jennifer S. Ogeer-Gyles DVM
    Abstract Objective: To review the human and companion animal veterinary literature on nosocomial infections and antimicrobial drug resistance as they pertain to the critically ill patient. Data sources: Data from human and veterinary sources were reviewed using PubMed and CAB. Human data synthesis: There is a large amount of published data on nosocomially-acquired bloodstream infections, pneumonia, urinary tract infections and surgical site infections, and strategies to minimize the frequency of these infections, in human medicine. Nosocomial infections caused by multi-drug-resistant (MDR) pathogens are a leading cause of increased patient morbidity and mortality, medical treatment costs, and prolonged hospital stay. Epidemiology and risk factor analyses have shown that the major risk factor for the development of antimicrobial resistance in critically ill human patients is heavy antibiotic usage. Veterinary data synthesis: There is a paucity of information on the development of antimicrobial drug resistance and nosocomially-acquired infections in critically ill small animal veterinary patients. Mechanisms of antimicrobial drug resistance are universal, although the selection effects created by antibiotic usage may be less significant in veterinary patients. Future studies on the development of antimicrobial drug resistance in critically ill animals may benefit from research that has been conducted in humans. Conclusions: Antimicrobial use in critically ill patients selects for antimicrobial drug resistance and MDR nosocomial pathogens. The choice of antimicrobials should be prudent and based on regular surveillance studies and accurate microbiological diagnostics. Antimicrobial drug resistance is becoming an increasing problem in veterinary medicine, particularly in the critical care setting, and institution-specific strategies should be developed to prevent the emergence of MDR infections. The collation of data from tertiary-care veterinary hospitals may identify trends in antimicrobial drug resistance patterns in nosocomial pathogens and aid in formulating guidelines for antimicrobial use.

    Hypocalcemia in a critically ill patient

    JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 2 2005
    Tamara B. Wills DVM
    Abstract Objective: To present a case of clinical hypocalcemia in a critically ill septic dog. Case summary: A 12-year old, female spayed English sheepdog presented in septic shock 5 days following hemilaminectomy surgery. Streptococcus canis was cultured from the incision site. Seven days after surgery, muscle tremors were noted and a subsequent low serum ionized calcium level was measured and treated. Intensive monitoring, fluid therapy, and antibiotic treatment were continued because of the sepsis and hypocalcemia, but the dog was euthanized 2 weeks after surgery. New or unique information provided: Low serum ionized calcium levels are a common finding in critically ill human patients, especially in cases of sepsis, pancreatitis, and rhabdomyolysis. In veterinary patients, sepsis or streptococcal infections are not commonly thought of as a contributing factor for hypocalcemia. Potential mechanisms of low serum ionized calcium levels in critically ill patients include intracellular accumulation of calcium ions, altered sensitivity and function of the parathyroid gland, alterations in Vitamin D levels or activity, renal loss of calcium, and severe hypomagnesemia. Pro-inflammatory cytokines and calcitonin have also been proposed to contribute to low ionized calcium in the critically ill. Many veterinarians rely on total calcium levels instead of serum ionized calcium levels to assess critical patients and may be missing the development of hypocalcemia. Serum ionized calcium levels are recommended over total calcium levels to evaluate critically ill veterinary patients. [source]


    Review article: bacterial translocation in the critically ill , evidence and methods of prevention

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2007
    M. GATT
    Summary Background Delayed sepsis, systemic inflammatory response syndrome (SIRS) and multiorgan failure remain major causes of morbidity and mortality on intensive care units. One factor thought to be important in the aetiology of SIRS is failure of the intestinal barrier resulting in bacterial translocation and subsequent sepsis. Aim This review summarizes the current knowledge about bacterial translocation and methods to prevent it. Methods Relevant studies during 1966,2006 were identified from a literature search. Factors, which detrimentally affect intestinal barrier function, are discussed, as are methods that may attenuate bacterial translocation in the critically ill patient. Results Methodological problems in confirming bacterial translocation have restricted investigations to patients undergoing laparotomy. There are only limited data available relating to specific interventions that might preserve intestinal barrier function or limit bacterial translocation in the intensive care setting. These can be categorized broadly into pre-epithelial, epithelial and post-epithelial interventions. Conclusions A better understanding of factors that influence translocation could result in the implementation of interventions which contribute to improved patient outcomes. Glutamine supplementation, targeted nutritional intervention, maintaining splanchnic flow, the judicious use of antibiotics and directed selective gut decontamination regimens hold some promise of limiting bacterial translocation. Further research is required. [source]


    Asymmetry in the intensive care unit: redressing imbalance and meeting the needs of family

    NURSING IN CRITICAL CARE, Issue 5 2008
    Denise Blanchard
    Abstract Aims and objectives:, The purpose of this study was to develop a way for nurses to understand how they negotiate and work with families in the intensive care unit (ICU). Background:, The importance of family to the critically ill patient is described in previous research; however, research exploring how to work with families in the clinical context of ICU is modest and there is little information and research to understand how the nurse might work to integrate family and understand family needs in the clinical context. Design:, The study was designed using action research methodology where an action research group of registered nurses from ICU proposed changes to how the family are defined, assessed and understood. Methods:, In the action research group and reflective conversations, the group planned new assessment tools to use in ICU to work with the family. Results:, Exploring their pragmatic knowledge of the context, the action research group suggested ways of working with families that did not impede the clinical work of the ICU. Families provided information about themselves and the patient that helped the nurse to plan care that redressed some of the asymmetrical nature of the relationship in the ICU. Conclusions:, This research created novel ways of viewing family and offers strategies to address asymmetry between families and ICU professionals. Relevance to clinical practice:, Positive steps to redress asymmetrical relationships can help ensure that family care is better integrated into ICU practice. [source]

    Regular Tracheostomy Tube Changes to Prevent Formation of Granulation Tissue

    THE LARYNGOSCOPE, Issue 1 2003
    Kathleen Yaremchuk MD
    Abstract Objectives/Hypothesis Tracheostomy is a commonly performed operative procedure that has been described since 2000 b.c. The early indications for tracheostomy were for upper airway obstruction, usually occurring in young people as a result of an infectious process. Recently, tracheostomies are more commonly performed in the critically ill patient to assist in long-term ventilatory support. Granulation tissue at the stoma and the trachea has been described as a late complication resulting in bleeding, drainage, and difficulty with maintaining mechanical ventilatory support. Study Design The present report is of an observational study of a newly implemented policy that required regular changing of tracheostomy tubes. Comparable groups of patients were compared before and after this procedural change to document complications. Data collection consisted of chart reviews of all admissions for 1 year before the policy change and the subsequent 2 years. Complication rates were compared using standard statistical techniques. Methods A policy change was instituted that required all tracheostomy tubes to be changed every 2 weeks in conjunction with a detailed evaluation of the tracheostomy stoma. Charts were reviewed the year before the change in policy and in the subsequent 2 years to determine the incidence of granulation tissue requiring operative intervention. Results The number of patients requiring surgical intervention secondary to granulation tissue showed a statistically significant decrease (P = .02). A review of policies and procedures from the six largest hospitals in southeastern Michigan had no recommendations for routine tracheostomy tube changes. Conclusions A policy requiring a routine change of tracheostomy tubes results in fewer complications from granulation tissue. Tracheostomy tube changes to prevent granulation tissue and its complications. [source]


    Monitoring sedation in the critically ill child

    ANAESTHESIA, Issue 5 2010
    A. Lamas
    Summary Sedation is an essential part of the management of the critically ill child, and its monitoring must be individualised and continuous in order to adjust drug doses according to the clinical state. There is no ideal method for evaluating sedation in the critically ill child. Haemodynamic variables have not been found to be useful. Clinical scales are useful when sedation is moderate, but are limited by their subjective nature, the use of stimuli, and the impossibility of evaluating profoundly sedated patients or those receiving neuromuscular blocking drugs; in addition, many of these scales have not been evaluated in children. The COMFORT scale is the most appropriate, as it was designed and validated for critically ill children requiring mechanical ventilation. Electroencephalography-derived methods permit continuous monitoring, provide an early indication of changes in the level of sedation, and facilitate a rapid adjustment of medication. However, these methods were designed and validated for patients under anaesthesia and their results cannot be fully extrapolated to the critically ill patient; in addition, some of them have not been validated in small children and there is still little experience in critically ill children. The main indications for the use of these methods are in patients with deep sedation and/or neuromuscular blockade. The bispectral index is the most widely used method at the present time. Analysis and comparison of the efficacy of the different methods for evaluating sedation in the critically ill child is required. [source]

    Airway fire due to diathermy during tracheostomy in an intensive care patient

    ANAESTHESIA, Issue 5 2001
    S. A. Rogers
    We describe a case of airway fire in an 83-year-old, critically ill patient. The fire occurred during a surgical tracheostomy under general anaesthesia, following ignition of the tracheal tube by diathermy. After debridement of the burnt tissue and treatment with intravenous antibiotics and glucocorticoids, the patient's respiratory function worsened initially. The patient eventually recovered without long-term sequelae and was discharged from the intensive care unit. The circumstances of this and other similar incidents are reviewed, as are the suggested methods for preventing this frightening occurrence. [source]


    Present and future role of Mental Illness Advocacy Associations in the management of the mentally ill: realities, needs and hopes at the edge of the third millennium

    BIPOLAR DISORDERS, Issue 3p2 2000
    Paolo Lucio Morselli
    Objective: The purpose of the present review is the analysis of the development and current status of the Mental Illness Advocacy Movement in the USA and in Europe, as well as of the role such a movement is playing in the management of the mentally ill. Methods: Information on the issue has been collected via literature search and several personal inquiries and contacts with different Mental Illness Advocacy Groups in the USA and in Europe. Results: The findings indicate that the Mental Illness Advocacy Movement is very alive and in full growth. Its role in the management of the mentally ill has become more and more important over the years. In several countries, it makes it possible to overcome some of the deficiencies of the National or Private Health Services. Thanks to the actions of the various Mental Illness Advocacy Groups, today, patients and families are more and better informed of their conditions and their rights. In many cases, this results in earlier diagnosis, better compliance and better outcomes. However, despite significant improvement in the status of the mentally ill patient, much still remains to be done. Conclusions: We need an improved dialogue with mental heath providers, public administrators, mental health policy makers, mass media and politicians. The dialogue between primary care team and the specialist must also be improved. A global alliance for action is needed to ensure better and more available services to those who suffer from mental disorders. [source]


    A Prospective Comparison of Ultrasound-guided and Blindly Placed Radial Arterial Catheters

    ACADEMIC EMERGENCY MEDICINE, Issue 12 2006
    Stephen Shiver MD
    Abstract Background Arterial cannulation for continuous blood-pressure measurement and frequent arterial-blood sampling commonly are required in critically ill patients. Objectives To compare ultrasound (US)-guided versus traditional palpation placement of arterial lines for time to placement, number of attempts, sites used, and complications. Methods This was a prospective, randomized interventional study at a Level 1 academic urban emergency department with an annual census of 78,000 patients. Patients were randomized to either palpation or US-guided groups. Inclusion criteria were any adult patient who required an arterial line according to the treating attending. Patients who had previous attempts at an arterial line during the visit, or who could not be randomized because of time constraints, were excluded. Enrollment was on a convenience basis, during hours worked by researchers over a six-month period. Patients in either group who had three failed attempts were rescued with the other technique for patient comfort. Statistical analysis included Fisher's exact, Mann-Whitney, and Student's t-tests. Results Sixty patients were enrolled, with 30 patients randomized to each group. Patients randomized to the US group had a shorter time required for arterial line placement (107 vs. 314 seconds; difference, 207 seconds; p = 0.0004), fewer placement attempts (1.2 vs. 2.2; difference, 1; p = 0.001), and fewer sites required for successful line placement (1.1 vs. 1.6; difference, 0.5; p = 0.001), as compared with the palpation group. Conclusions In this study, US guidance for arterial cannulation was successful more frequently and it took less time to establish the arterial line as compared with the palpation method. [source]

    Cardiac output, usually expressed as liters of blood ejected by the left ventricle per minute, is a fundamental measure of the adequacy of myocardial function to meet the perfusion needs of tissue at any time. Decreases in cardiac output over time (when cardiac output is measured under similar conditions) may signal myocardial functional deterioration and the onset or progression of heart failure. Conversely, improvements in cardiac output may indicate a positive response to medical therapy. However, most methods for evaluating cardiac output are technically demanding, require specialized training and specialized environments for measurement, and are costly. Therefore, most measurement techniques are impractical for routine evaluation of disease progression and/or response to treatment in the prevention and/or management of heart failure. This paper provides a comparative overview of commonly employed cardiac output measurement strategies with emphasis on developments in impedance cardiography which suggest that impedance cardiography has the potential to make routine assessment and trending of cardiac output a viable alternative to assist in the management of both chronically and acutely ill patients, including those with heart failure.

    A randomized, placebo-controlled trial of paroxetine in nursing home residents with non-major depression

    DEPRESSION AND ANXIETY, Issue 3 2002
    Adam B. Burrows M.D.
    Abstract Depression is common across a broad spectrum of severity among nursing home residents. Previous research has demonstrated the effectiveness of antidepressants in nursing home residents with major depression, but it is not known whether antidepressants are helpful in residents with less severe forms of depression. We conducted a randomized double-blind placebo-controlled 8-week trial comparing paroxetine and placebo in very old nursing home residents with non-major depression. The main outcome measure was the primary nurse's Clinical Impression of Change (CGI-C). Additional outcome measures were improvement on the interview-derived Hamilton Depression Rating Scale (HDRS) and Cornell Scale for Depression (CS) scores. Twenty-four subjects with a mean age of 87.9 were enrolled and twenty subjects completed the trial. Placebo response was high, and when all subjects were considered, there were no differences in improvement between the paroxetine and placebo groups. Two subjects that received paroxetine developed delirium, and subjects that received paroxetine were more likely to experience a decrease in Mini Mental State Exam scores (P = .03). There were no differences in serum anticholinergic activity between groups. In a subgroup analysis of 15 subjects with higher baseline HDRS and CS scores, there was a trend toward greater improvement in the paroxetine group in an outcome measure that combined the CGI-C and interview-based measures (P = .06). Paroxetine is not clearly superior to placebo in this small study of very old nursing home residents with non-major depression, and there is a risk of adverse cognitive effects. Because of the high placebo response and the trend towards improvement in the more severely ill patients, it is possible that a larger study would have demonstrated a significant therapeutic effect for paroxetine as compared with placebo. The study also illustrates the discordance between patient and caregiver ratings, and the difficulties in studying very elderly patients with mood disorders.

    Limited Opportunities for Paramedic Student Endotracheal Intubation Training in the Operating Room

    ACADEMIC EMERGENCY MEDICINE, Issue 10 2006
    Bradford D. Johnston MD
    Abstract Background Paramedics, who often are the first to provide emergency care to critically ill patients, must be proficient in endotracheal intubation (ETI). Training in the controlled operating room (OR) setting is a common method for learning basic ETI technique. Objectives To determine the quantity and nature of OR ETI training currently provided to paramedic students. Methods The authors surveyed directors of paramedic training programs accredited by the Commission on Accreditation of Allied Health Education Programs. An anonymous 12-question, structured, closed-response survey instrument was used that requested information regarding the duration and nature of OR training provided to paramedic students. The results were analyzed by using descriptive statistics. Results From 192 programs, 161 completed surveys were received (response rate, 85%). OR training was used at 156 programs (97%) but generally was limited (median, 17,32 hours per student). Half of the programs provided fewer than 16 OR hours per student. Students attempted a limited number of OR ETI (median, 6,10 ETI). Most respondents (61%) reported competition from other health care students for OR ETI. Other identified hindering factors included the increasing OR use of laryngeal mask airways and physicians' medicolegal concerns. Respondents from 52 (33%) programs reported a recent reduction in OR access, and 56 (36%) programs expected future OR opportunities to decrease. Conclusions Despite its key role in airway management education, the quantity and nature of OR ETI training that is available to paramedic students is limited in comparison to that available to other ETI providers.

    Cognitive subprocesses and schizophrenia.

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 2001

    Objective:,The aim of the study is to demonstrate that deficits of information processing in schizophrenic patients can be isolated with reaction-time (RT) decomposition paradigms. Method:,Three types of visually presented tasks were applied: simple, disjunctive and choice RT-tasks. RT were split into movement latency and time necessary to execute movements. Comparisons of three samples of schizophrenic patients (295.3) with individually matched (age, sex, education and handedness) healthy controls are presented: Sample 1: 10 drug-naive first-onset patients, Sample 2: 10 neuroleptically treated first-onset patients, Sample 3: 10 neuroleptically treated chronically ill patients. Results:,Findings indicate that schizophrenia affects primarily subprocesses in which percepts are translated into appropriate actions (response-selection). Neuroleptic treatment improves processing at this stage but is accompanied by slowing of movement execution. Conclusion:,Response-selection is selectively impaired in first-onset patients. This disturbance, which might be specific for schizophrenia, can be regarded as indication of a disconnection between frontal and posterior areas. [source]


    Role of fine-needle aspirate immunophenotyping by flow cytometry in rapid diagnosis of lymphoproliferative disorders

    DIAGNOSTIC CYTOPATHOLOGY, Issue 7 2007
    Ritu Gupta M.D.
    Abstract Immunophenotyping is an essential component in the diagnostic work-up of lymphoproliferative disorders (LPD). As compared to immunohistochemistry, flow cytometric immunophenotyping (FCMI) is rapid, quantitative and a more objective technique. This study was designed to evaluate the utility of FCMI on fine needle aspirates (FNA) in rapid diagnosis of LPD in routine clinical practice. FNA from 31 consecutive cases clinically suggestive of LPD were subjected to FCMI. Representative material for FCMI was obtained in 28 (90%) cases and a definite diagnosis established in 27 cases. Histopathogical correlation was available in 22 cases and concordance with FCMI results was observed in 19 (86.4%) cases. FCMI analysis was inconclusive in 4 cases. The results of FCMI were available the same day and were crucial for therapeutic purpose in 3 patients with superior vena cava syndrome. FCMI combined with cytological examination of aspirate smears permits rapid diagnosis with high level of accuracy resulting in efficient treatment planning for critically ill patients and those from far-off rural areas.

    Potential use of insulin as an anti-inflammatory drug

    DRUG DEVELOPMENT RESEARCH, Issue 3 2008
    Paresh Dandona
    Abstract Acute hyperglycemia worsens morbidity and mortality in critically ill patients. The control of hyperglycemia with insulin improves clinical outcomes in patients with a stay of more than 3,5 days in the intensive care unit (ICU) and in coronary artery bypass graft (CABG) patients. However, clinical benefits of insulin infusion have not been seen consistently in patients with acute coronary syndromes. Since all previous studies in the ICU have centered on the normalization of glycemia, we still do not know whether insulin exerts beneficial effects over and above those observed with reduction of blood glucose concentrations. The regimens used in acute coronary syndromes infuse fixed doses of insulin with high rates of glucose and are usually associated with hyperglycemia; this may neutralize the beneficial effects of insulin. In this article, we discuss data demonstrating an anti-inflammatory effect of insulin and a pro-inflammatory effect of glucose. We provide a mechanistic justification for the benefits of maintaining euglycemia with insulin infusions in the hospitalized patients. To investigate the clinical benefits of the anti-inflammatory effects of insulin, we also suggest further investigations directed toward optimization of insulin infusion regimens to determine whether restoration of glucose levels toward normal with higher infusion rates and concentrations of insulin will lead to further improvement in outcomes in the critical care and acute coronary syndromes.
