ABSTRACTFeatures consistent with the syndrome known as excited delirium (ExDS) have been associated with law enforcement restraint-related death. The pathophysiology and exact causative factors of restraint-related death associated with ExDS remain unclear. We present a case of successful field resuscitation of a man with ExDS who experienced cardiopulmonary arrest while being restrained by law enforcement officers. Despite the presence of a severe lactic acidosis on emergency department admission, the patient recovered following prehospital treatment with advanced cardiac life support measures and intravenous sodium bicarbonate, likely in part due to early recognition of the disease process.

ABSTRACTDipyridamole/technetium sestamibi scans (more commonly known as MIBI scans, an acronym for methoxyisobutyl isonitrile) are used commonly for the diagnosis and risk stratification of coronary artery disease. Adverse events from MIBI scans are extremely rare. We present the case of a 64-year-old man who was successfully resuscitated after two asystolic episodes following dipyridamole infusion for a MIBI scan. ⋯ To our knowledge, there are no previous reports of patients having two discrete asystolic episodes or an asystolic episode as delayed as we report after a MIBI scan. Our case illustrates why emergency physicians should be aware of the potential for asystole following MIBI scanning and why aminophylline, the antidote for dipyridamole, should be readily available in emergency departments that could see patients after pharmacologic stress testing. Patients who become asystolic following dipyridamole infusion likely require prolonged cardiac monitoring, given the potential for further episodes after periods of hemodynamic stability.

ABSTRACTObjectives:Current guidelines emphasize that emergency department (ED) patients at low risk for potential ischemic chest pain cannot be discharged without extensive investigations or hospitalization to minimize the risk of missing acute coronary syndrome (ACS). We sought to derive and validate a prediction rule that permitted 20 to 30% of ED patients without ACS safely to be discharged within 2 hours without further provocative cardiac testing. Methods:This prospective cohort study enrolled 1,669 chest pain patients in two blocks in 2000-2003 (development cohort) and 2006 (validation cohort). ⋯ The validation of the rule was limited by the lack of consistency in data capture, incomplete follow-up, and lack of evaluation of the accuracy, comfort, and clinical sensibility of this clinical decision rule. Conclusion:The Vancouver Chest Pain Rule may identify a cohort of ED chest pain patients who can be safely discharged within 2 hours without provocative cardiac testing. Further validation across other centres with consistent application and comprehensive and uniform follow-up of all eligible and enrolled patients, in addition to measuring and reporting the accuracy of and comfort level with applying the rule and the clinical sensibility, should be completed prior to adoption and implementation.

Studying workflow is a critical step in designing, implementing and evaluating informatics interventions in complex sociotechnical settings, such as hospital emergency departments (EDs). Known approaches to studying workflow in clinical settings attend to the activities of individual clinicians, thus being inadequate to characterize patient care as a cooperative work. ⋯ The patient-oriented workflow methodology has the potential to facilitate modeling patient care in EDs by characterizing both roles and activities in sequence. The methodology also provides researchers and practitioners a more realistic and comprehensive workflow perspective that can inform the design, implementation and evaluation of health information technology interventions.

Emergency departments (EDs) are an essential component of any developed health care system. There is, however, no national description of EDs in Switzerland. Our objective was to establish the number and location of EDs, patient visits and flow, medical staff and organization, and capabilities in 2006, as a benchmark before emergency medicine became a subspecialty in Switzerland. ⋯ Swiss EDs were significant providers of health care in 2006. Crowding, physicians with limited experience, and the heterogeneity of emergency care capabilities were likely threats to the ubiquitous and consistent delivery of quality emergency care, particularly for time-sensitive conditions. Our survey establishes a benchmark to better understand future improvements in Swiss emergency care.
