We hypothesized that optimal positioning of the head and neck to protect the spinal cord during cervical spine immobilization can be determined with reference to external landmarks. In this study we sought to determine the optimal position for cervical spine immobilization using magnetic resonance imaging (MRI) and to define this optimal position in a clinically reproducible fashion. ⋯ In healthy adults, a slight degree of flexion equivalent to 2 cm of occiput elevation produces a favorable increase in spinal canal/spinal cord ration at levels C5 and C6, a region of frequent unstable spine injuries.

To determine the efficacy of outpatient rapid i.v. rehydration in correcting dehydration and resolving vomiting in children with mild to moderate dehydration resulting from acute gastroenteritis. ⋯ Outpatient rapid i.v. rehydration is safe and effective in correcting dehydration and resolving vomiting in selected children with acute gastroenteritis and mild to moderate dehydration. In our study, most children who presented with a serum bicarbonate concentration greater than 13 mEq/L tolerated oral fluids after rapid i.v. rehydration and were further managed as outpatients without complications. By contrast, most children with a serum bicarbonate concentration of 13 mEq/L or less usually did not tolerate oral fluids after rapid i.v. rehydration and required more prolonged i.v. fluid therapy. All discharged patients, regardless of their serum bicarbonate concentration, demonstrated the ability to tolerate orally administered fluid.

Intraosseous adenosine for the termination of supraventricular tachycardia in an infant.
In recent years, the intraosseous technique has dramatically improved the speed at which vascular access may be achieved in critically ill children, and adenosine has been shown to rapidly convert supraventricular tachycardia to normal sinus rhythm. Until now, no report has demonstrated that this drug may be effectively given by this route in human beings. This case report describes the successful termination of supraventricular tachycardia in an infant with the intraosseous administration of adenosine.

To evaluate a program using health care preprofessional college students as research associates (RAs) to facilitate research in emergency medicine. ⋯ College students serving as research associates can be an economical and successful tool for clinical studies in the emergency department.
