Several methods have been proposed to evaluate neurological outcome in out-of-hospital cardiac arrest (OHCA) patients. Blood lactate has been recognized as a reliable prognostic marker for trauma, sepsis, or cardiac arrest. The objective of this study was to examine the association between initial lactate level or lactate clearance and neurologic outcome in OHCA survivors who were treated with therapeutic hypothermia. ⋯ The lactate clearance rate, and not the initial lactate level, was associated with neurological outcome in OHCA patients after therapeutic hypothermia.

ABSTRACTIntroduction:Although emergency departments (EDs) in Canada's rural areas serve approximately 20% of the population, a serious problem in access to health care services has emerged. Objective:The objective of this project was to compare access to support services in rural EDs between British Columbia and Quebec. Methods:Rural EDs were identified through the Canadian Healthcare Association's Guide to Canadian Healthcare Facilities. ⋯ Rural EDs in Quebec are also supported by a greater proportion of intensive care units (88% versus 15%); however, British Columbia appears to have more medevac aircraft/helicopters than Quebec. Conclusions:The results suggest that major differences exist in access to support services in rural EDs in British Columbia and Quebec. A nationwide study is justified to address this issue of variability in rural and remote health service delivery and its impact on interfacility transfers and patient outcomes.

Sepsis often is characterized by an acute brain dysfunction, which is associated with increased morbidity and mortality. Its pathophysiology is highly complex, resulting from both inflammatory and noninflammatory processes, which may induce significant alterations in vulnerable areas of the brain. Important mechanisms include excessive microglial activation, impaired cerebral perfusion, blood-brain-barrier dysfunction, and altered neurotransmission. ⋯ Currently, the management of brain dysfunction mainly consists of control of sepsis and prevention of all aggravating factors, including metabolic disturbances, drug overdoses, anticholinergic medications, withdrawal syndromes, and Wernicke's encephalopathy. Modulation of microglial activation, prevention of blood-brain-barrier alterations, and use of antioxidants represent relevant therapeutic targets that may impact significantly on neurologic outcomes. In the future, investigations in patients with sepsis should be undertaken to reduce the duration of brain dysfunction and to study the impact of this reduction on important health outcomes, including functional and cognitive status in survivors.

ABSTRACTBackground:The RAPID approach (Resuscitation, Analgesia and assessment, Patient needs, Interventions, Disposition) was developed as an approach to managing emergency department patients. It is a mental checklist to help trainees provide comprehensive care, addressing issues in priority. Its impact on trainee performance has not been assessed. ⋯ Conclusions:Students exposed to the RAPID approach at the start of their emergency medicine rotation performed better on the one component of the written examination for which it was designed to improve performance. Students found it to be a useful mental checklist for comprehensive care, possibly addressing the hidden curriculum. Emergency medicine educators should consider further study and careful implementation of the RAPID approach.

Comparative StudyAssessment of cardiac pathology by point-of-care ultrasonography performed by a novice examiner is comparable to the gold standard.
The aim of the study was to compare the diagnostic accuracy of point-of-care cardiac ultrasonography performed by a novice examiner against results from a specialist in cardiology with expert skills in echocardiography, with regard to the assessment of six clinically relevant cardiac conditions in a population of ward patients from the Department of Cardiology or the Department of Cardiothoracic Surgery. ⋯ This study showed that a novice examiner was able to detect common and significant heart pathology in six different categories with good accuracy using POC ultrasonography.
