Life-threatening Event (life-threatening + event)
Kinds of Life-threatening Event Selected AbstractsPulmonary Artery Dissection: Echocardiographic Findings and DiagnosisECHOCARDIOGRAPHY, Issue 4 2003Daniel Areco Pulmonary artery dissection is a rare but life-threatening event, predisposing to sudden cardiac death or cardiogenic shock. It is often associated with underlying congenital disorders predisposing to pulmonary hypertension. Rarely, it is diagnosed by echocardiography or other image techniques. We present a case report of a pulmonary artery dissection, diagnosed primarily by echocardiography. The patient died soon after refusing any interventional approach after a short period under medication. (ECHOCARDIOGRAPHY, Volume 20, May 2003) [source] Matched case,control study to evaluate risk factors for hyperlactataemia in HIV patients on antiretroviral therapyHIV MEDICINE, Issue 4 2003D Datta Background Lactic acidosis is a life-threatening event during antiretroviral therapy (ART). Hyperlactataemia may be a prelude to acidosis. Our database study suggested that female gender, intercurrent illness and didanosine (ddI)-based regimens may increase risk of lactic acidosis. The aim of this matched case,control study was to identify risk factors for hyperlactataemia requiring screening. Methods Cases were defined as patients with two consecutive lactate samples ,3.5 mmol/L taken more than 1 week apart. Cases were matched to two controls on gender, use of ddI and total duration of therapy using a 6-month window on either side. Controls never had raised lactate >2.5 mmol/L. A conditional logistic regression analysis using the PHREG procedure in SAS (SAS Institute Inc, Cary, NC) was performed with a discreet logistic model stratified by matching variables. Results Twenty-one cases were matched to 42 controls. In the univariate model, current use of stavudine (d4T), total cholesterol >5.3 mmol/L and glucose levels ,5.2 mmol/L gave increased likelihood of persistent hyperlactataemia. The multivariate model showed current use of d4T to be a significant independent predictor of persistent hyperlactataemia. Conclusions The results of this case,control study indicate that, when controlling for ddI use, d4T use is an additional risk factor for hyperlactataemia. [source] Novel Nursing Terminologies for the Rapid Response SystemINTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 2 2009Elizabeth Wong CRNA PURPOSE., Nursing terminology with implications for the rapid response system (RRS) is introduced and proposed: critical incident nursing diagnosis (CIND), defined as the recognition of an acute life-threatening event that occurs as a result of disease, surgery, treatment, or medication; critical incident nursing intervention, defined as any indirect or direct care registered nurse-initiated treatment, based upon clinical judgment and knowledge that a registered nurse performs in response to a CIND; and critical incident control, defined as a response that attempts to reverse a life-threatening condition. DATA SOURCES., The current literature, research studies, meta-analyses from a variety of disciplines, and personal clinical experience serve as the data sources for this article. DATA SYNTHESIS., The current nursing diagnoses, nursing interventions, and nursing outcomes listed in the North American Nursing Diagnosis Association International Classification, Nursing Interventions Classification (NIC), and Nursing Outcomes Classification (NOC), respectively, are inaccurate or inadequate for describing nursing care during life-threatening situations. The lack of such standardized nursing terminology creates a barrier that may impede critical communication and patient care during life-threatening situations when activating the RRS. CONCLUSIONS., The North American Nursing Diagnosis Association International Classification, NIC, and NOC are urged to refine their classifications and include CIND, critical incident nursing intervention, and critical incident control. The RRS should incorporate standardized nursing terminology to describe patient care during life-threatening situations. IMPLICATIONS FOR NURSING PRACTICE., Refining the diagnoses, interventions, and outcomes classifications will permit nursing researchers, among others, to conduct studies on the efficacy of the proposed novel nursing terminology when providing care to patients during life-threatening situations. In addition, including the proposed novel nursing terminology in the RRS offers a means of improving care in such situations.

[source] Predictors of medication compliance among older heart failure patientsINTERNATIONAL JOURNAL OF OLDER PEOPLE NURSING, Issue 4 2007Krystyna Cholowski PhD Aim. To examine relationships between psycho-social and patho-physiological measures in explaining medication compliance in older heart failure (HF) patients. Background. Self-efficacy is a predictor not only of medication compliance, but also health recovery. How older HF patients conceptualize and manage this life-threatening event is central to ongoing rehabilitation. Regulating ongoing medical and lifestyle changes in the rehabilitation process requires that any underlying negative affect be productively managed by the use of appropriate coping strategies. Method. Using an exploratory correlational design, 51 older HF patients were asked to complete the Beck Depression Inventory, Beliefs about Medication and Diet Questionnaire, Reactions to Daily Events Questionnaire and Self-regulation scale. A self-report measure of medication compliance was obtained as part of a semi-structured interview. The study was conducted in 2003,2004. Results. Using descriptive statistics, patho-physiological and psychosocial characteristics were given. Independent t -tests were used to assess the gender effects. Pairwise correlations were used to examine the relationships between presenting circumstances, psychosocial characteristics, medication compliance beliefs and self-reported medication compliance behaviours. All positive coping strategies and self-regulation were associated with positive intentions in medication compliance. Males were more inclined towards proactive coping and self-regulatory strategies than were females. Increased depressive symptoms were linked to carelessness in compliance. A belief in medication compliance was associated with a reduced likelihood of carelessness Conclusion. Bandura's three conditions for agency in rehabilitation, self-efficacy and goal-directed intention appeared to be important even in the early phase of the programme. Positive coping strategies and self-regulation suggests a positive basis for medication compliance and more successful ongoing rehabilitation for older HF patients. We identify a significantly enhanced educative role for nurses in this context. Relevance to clinical practice. We suggest that nurses dealing with compliance issues among older patients need to monitor behaviour through addressing both the quality of affect during the patient's response to HF (self-concept, -esteem and -efficacy) as well as the quality of health-related metacognitive knowledge underlying the self-regulatory decisions (such as the patients conceptions of ,wellness' and the strategic knowledge underpinning its achievement and maintenance). [source] Systematic review: the extra-oesophageal symptoms of gastro-oesophageal reflux disease in childrenALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 3 2009V. TOLIA Summary Background, Extra-oesophageal symptoms are thought to be common, atypical symptoms of gastro-oesophageal reflux disease (GERD) in children. Aim, To investigate the prevalence of GERD in children with extra-oesophageal symptoms or of extra-oesophageal symptoms in children with GERD, and the effect of GERD therapies on extra-oesophageal symptoms. Methods, A systematic review of articles in PubMed and EMBASE. Results, We identified 18 relevant articles. The pooled weighted average prevalence of GERD in asthmatic children was 23%, compared with 4% in healthy controls from the same five studies. The majority of studies evaluating the relationship between apparent life-threatening event (ALTE) and GERD did not suggest a causal relationship. Seven studies reported that respiratory symptoms, sinusitis and dental erosion were significantly more prevalent in children with GERD than in controls. Data from pharmacotherapeutic trials were inconclusive and provided no support for a causal relationship between GERD and extra-oesophageal symptoms. Conclusions, Possible associations exist between GERD and asthma, pneumonia, bronchiectasis, ALTE, laryngotracheitis, sinusitis and dental erosion, but causality or temporal association were not established. Moreover, the paucity of studies, small sample sizes and varying disease definitions did not allow firm conclusions to be drawn. Most trials of GERD therapies showed no improvement in extra-oesophageal symptoms in children. [source] Recovering from the psychological impact of intensive care: how constructing a story helpsNURSING IN CRITICAL CARE, Issue 6 2009Susan 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] Thalamic infarct presenting as apparent life-threatening event in infantsACTA PAEDIATRICA, Issue 12 2009Sachin Gupta Abstract Thalamic infarction with distinct manifestations is well-described in adults but less well-delineated in children. We report two infants who presented with an apparent life-threatening event (ALTE) with very early magnetic resonance imaging (MRI) demonstrating a unilateral thalamic infarction. Subsequent MRI demonstrated bilateral changes in the brain stem and basal ganglia, which were in keeping with profound hypoxic ischaemic injury. We propose the thalamic infarction to be the primary event precipitating a profound hypoxic ischaemic injury as an alternative explanation to the neuroimaging observation. Conclusion:, Thalamic infraction may have a causal role in ALTE. Early and appropriate neuroimaging is required to detect these changes. [source] Cholinergic and oxidative stress mechanisms in sudden infant death syndromeACTA PAEDIATRICA, Issue 11 2009Anne Dick Abstract Aim:, To determine whether biochemical parameters of cholinergic and oxidative stress function including red cell acetylcholinesterase (AChE), serum/plasma thyroglobulin, selenium, iron, ferritin, vitamins C, E, and A affect risk in apparent life-threatening event (ALTE), sudden infant death syndrome (SIDS), and sudden unexpected death in infancy (SUDI). To assess these biochemical parameters as a function of age; and for influence of pharmacology and epidemiology, including infant health, care, and feeding practices. Methods:, A multicentre, case,control study with blood samples from 34 ALTE and 67 non-ALTE (control) infants matched for age, and 30 SIDS/SUDI and four non-SIDS/non-SUDI (post-mortem control) infants. Results:, Levels/activity of the biochemical parameters were not significantly different in ALTE vs. control infants, with the exception of higher vitamin C levels in the ALTE group (p = 0.009). In ALTE and control groups, AChE and thyroglobulin levels increased and decreased respectively from birth to attain normal adult levels from 6 months. Levels of iron and ferritin were higher in the first 6 month period for all infant groups studied, intersecting with vitamin C levels peaking around 4 months of age. Conclusion:, Lower AChE levels and higher combined levels of iron and vitamin C in the first 6 months of life may augment cholinergic and oxidative stress effect, particularly at the age when SIDS is most prevalent. This may contribute to risk of ALTE and SIDS/SUDI events during infancy. [source] Abnormal heart rate response to hypercapnia in boys with an apparent life-threatening eventACTA PAEDIATRICA, Issue 12 2002A Edner Aim: To determine instantaneous cardiac variability responses to increased carbon dioxide (CO2) during quiet sleep in infants who may be at risk for the Sudden Infant Death syndrome (SIDS). Methods: The cardiac rate variability before, during and after a CO2 challenge was examined in 41 infants who had experienced an apparent life-threatening event (ALTE) and 41 gender- and age-matched control infants. Results: The ALTE infants responded to CO2 breathing with a significant increase in R-R intervals, i.e. decreases in heart rate, compared to the controls (45.1% increase in R-R intervals vs. 41.4%; p= 0.005). The differences between ALTE infants and controls depended primarily on the boys' responses. Conclusion: ALTE infants, particularly ALTE boys, have an autonomic dysfunction,lower sympathetic stimulation and/or inhibited vagal withdrawal when stressed with CO2. The outcome might provide clues to the mechanisms underlying the cardiovascular processes contributing to the terminal event in SIDS. [source] Nonepileptic Disorders Imitating Generalized Idiopathic EpilepsiesEPILEPSIA, Issue 2005Natalio Fejerman Summary:, Differential diagnosis between epileptic and nonepileptic paroxysmal disorders is fundamental not only to allow correct management of patients but also to avoid the burden of unnecessary antiepileptic medication. The focus of this chapter is limited to imitators of idiopathic generalized epilepsies (IGE) which are expressed through myoclonic, tonic,clonic, tonic, atonic, and absence seizures. Apparent losses of consciousness and drop attacks also have to be considered. Benign myoclonus of early infancy is the main nonepileptic disorder in the differential diagnosis of infantile spasms, but is not dealt with here because West syndrome is not an IGE. Hyperekplexia, metabolic disorders, hypnagogic myoclonus, and disturbed responsiveness caused by the use of drugs are listed in Table 1. Other conditions that may imitate more focal epileptic seizures are omitted. Benign neonatal sleep myoclonus, apnea and apparent life-threatening events in infants, cyanotic and pallid breath-holding spells, syncope, staring spells, psychogenic seizures, hyperventilation syndrome, and narcolepsy have been selected based on frequency or difficulties in differential diagnosis with the intention to cover the most conspicuous imitators of IGE in different ages.

Nonepileptic disorders imitating idiopathic generalized epilepsies [source] Adult nephrotic syndrome: Non-specific strategies for treatment (Review Article)NEPHROLOGY, Issue 1 2008JOHN A CHARLESWORTH SUMMARY: Irrespective of aetiology, the nephrotic syndrome presents a range of potentially serious complications. These include thrombo-embolism, infection and hyperlipidaemia. Despite the prevalence of the nephrotic state among renal patients, there has been little prospective analysis of the therapeutic approach to these potentially life-threatening events even though their pathogenesis has been examined in some detail. Most of these complications are more prevalent once the albumin concentration falls below 20 g/L and it is recognized that restoration of serum albumin significantly diminishes their frequency. However, this may be difficult to achieve, especially in adults. The problems of thrombo-embolism and infection are of immediate concern but, in persistent cases, the additional issues of hyperlipidaemia and loss of bone density also require consideration for therapy. Thus, in addition to specific attempts to reduce proteinuria, it is recommended that high-risk nephrotic patients receive anticoagulation, pneumococcal vaccination and lipid lowering therapy. Strategies for the preservation of bone density should also be considered, particularly in patients who receive high-dose corticosteroids. Among a range of non-specific treatments for proteinuria, angiotensin-converting enzyme inhibitors appear best in terms of efficacy and safety. Prospective trials are required to clarify the longitudinal impact of these generic strategies on the protection of the persistently nephrotic patient. [source] How Revealing Are Insertable Loop Recorders in Pediatrics?PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 3 2008PATRICIA A. FRANGINI M.D. Introduction: An insertable loop recorder (ILR) in patients with infrequent syncope or palpitations may be useful to decide management strategies, including clinical observation, medical therapy, pacemaker, or implantable cardioverter defibrillator (ICD). We sought to determine the diagnostic utility of the Reveal® ILR (Medtronic, Inc., Minneapolis, MN, USA) in pediatric patients. Methods: Retrospective review of clinical data, indications, findings, and therapeutic decision in 27 consecutive patients who underwent ILR implantation from 1998,2007. Results: The median age was 14.8 years (2,25 years). Indications were syncope in 24 patients and recurrent palpitations in three. Overall, eight patients had structural heart disease (six congenital heart disease, one hypertrophic cardiomyopathy, one Kawasaki), five had previous documented ventricular arrhythmias with negative evaluation including electrophysiology study, and three patients had QT prolongation. Tilt testing was performed in 10 patients, of which five had neurocardiogenic syncope but recurrent episodes despite medical therapy. After median three months (1,20 months), 17 patients presented with symptoms and the ILR memory was analyzed in 16 (no episode stored in one due to full device memory), showing asystole or transient atrioventricular (AV) block (2), sinus bradycardia (6), or normal sinus rhythm (8). Among asymptomatic patients, 3/10 had intermittent AV block or long pauses, automatically detected and stored by the ILR. In 19 of 20 patients, ILR was diagnostic (95%) and five subsequently underwent pacemaker implantation, while seven patients remained asymptomatic without ILR events. Notably, no life-threatening events were detected. The ILR was explanted in 22 patients after a median of 22 months, two due to pocket infection, 12 for battery depletion and eight after clear documentation of nonmalignant arrhythmia. Conclusions: The ILR in pediatrics is a useful adjunct to other diagnostic studies. Patient selection is critical as the ILR should not be utilized for malignant arrhythmias. A diagnosis is attained in the majority of symptomatic patients, predominantly bradyarrhythmias including pauses and intermittent AV block. [source] Laryngeal sensitivity in the neonatal period: From bench to bedsidePEDIATRIC PULMONOLOGY, Issue 8 2007Philippe Reix MD Abstract Laryngeal sensitivity in the newborn has been a subject of great interest for both researchers and clinicians for a number of years. From a clinical standpoint, laryngeal sensitivity is essential for both preventing foreign substances from entering into the lower airway and for finely tuning upper airway resistance. However, heightened reflexes originating from the laryngeal receptors in newborns and infants, due to neural immaturity, can lead to potentially dangerous cardiorespiratory events. The latter have been linked to apneas of prematurity, apparent life-threatening events, and sudden infant death syndrome (SIDS). From a physiological standpoint, many mechanisms pertaining to reflexes originating from laryngeal receptors are yet to be fully understood. This short review is an attempt to summarize current knowledge on laryngeal sensitivity and its potential consequences upon control of breathing abnormalities encountered within the first weeks of life.

[source] The evolving management of the third stage of labourBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2009AM Gülmezoglu The immediate postpartum period is a risky period because life-threatening events can occur unexpectedly, and lead to death if they are not managed promptly. Appropriate management of the third stage of labour can reduce severe postpartum haemorrhage and death. This commentary summarizes how various management techniques of third stage of labour evolved to date and the evidence base for current international recommendations. [source] Fatal infant nasal seawater spray instillationACTA PAEDIATRICA, Issue 6 2006Milivoj Novak Abstract The use of seawater nasal spray is considered safe and sold as a non-prescription medicine. However, it is well known that nasal manipulations can provoke vagal reaction leading to acute life-threatening events. A case of fatal seawater nasal spray application in an infant is presented. Conclusion: We do not consider the use of seawater nasal spray to be absolutely safe, especially among infants with disordered autonomic function. [source] Characteristics of respiratory syncytial virus-related apnoea in three infantsACTA PAEDIATRICA, Issue 6 2004M Rayyan Apnoea is a common sign in respiratory syncytial virus (RSV) infections in young infants and can be the first presentation of an acquired RSV infection. We describe polysomnographic recordings of three infants revealing prolonged RSV-related apnoea before RSV infection was diagnosed. The apnoeas were of central origin. The caregivers had not noted any apparent life-threatening events (ALTE) prior to the polysomnography. Cardiorespiratory monitoring after the acute infection did not reveal any further apnoeas. Conclusion: Central, prolonged apnoea can be the first sign of an acquired RSV infection in young infants in the absence of other respiratory symptoms and without any previous observation of apnoea by the caregivers.
