Background: The emergency department (ED) is a unique potential location for recruitment into studies of complementary and alternative medicine (CAM) therapies. We sought to determine the stated willingness of ED patients with musculoskeletal complaints to participate in CAM research for their presenting problem, and to determine the characteristics of this population.
Methods: The study was carried out in the ED of Vancouver General Hospital weekdays between 10 am and 6 pm from Oct.
Introduction: It may be appropriate for nurse practitioners (NPs) to provide care for a subset of emergency department (ED) patients with non-urgent problems. Our objective was to determine the attitude of ED patients with minor problems to being treated by an NP.
Methods: Consecutive adults who presented to this tertiary ED on weekdays between 8 am and 4 pm were eligible for the study if they had 1 of the following 18 complaints: minor abrasions or lacerations, minor bites, minor burns, minor extremity trauma, cast check, earache, superficial foreign body, lice or pinworms, morning-after pill request, needlestick injury or body-fluid exposure, prescription refill, puncture wound, sore throat, subconjunctival hemorrhage, suture removal or wound check, tetanus immunization request, toothache, or urinary tract infection (women).
Background: Endogenous adenosine might cause or perpetuate bradyasystole. Our aim was to determine whether aminophylline, an adenosine antagonist, increases the rate of return of spontaneous circulation (ROSC) after out-of-hospital cardiac arrest.
Methods: In a double-blind trial, we randomly assigned 971 patients older than 16 years with asystole or pulseless electrical activity at fewer than 60 beats per minute, and who were unresponsive to initial treatment with epinephrine and atropine, to receive intravenous aminophylline (250 mg, and an additional 250 mg if necessary) (n=486) or placebo (n=485).
Background: Coronary thrombosis and pulmonary thromboembolism are common causes of cardiac arrest. We assessed whether the administration of tissue plasminogen activator (t-PA) during cardiopulmonary resuscitation would benefit patients with cardiac arrest and pulseless electrical activity of unknown or presumed cardiovascular cause.
Methods: Patients who were older than 16 years of age and who had more than one minute of pulseless electrical activity that was unresponsive to initial therapy outside the hospital or in the emergency department were eligible.
