A Derivation and Validation Study of an Early Blood Transfusion Needs Score for Severe Trauma Patients.

Background: There is no existing adequate blood transfusion needs determination tool that Emergency Medical Services (EMS) personnel can use for prehospital blood transfusion initiation. In this study, a simple and pragmatic prehospital blood transfusion needs scoring system was derived and validated.

Methods: Local trauma registry data were reviewed retrospectively from 2004 through 2013.

Successful resuscitation of a patient in asystole after a TASER injury using a hypothermia protocol.

New studies have shown the benefit of initiating a hypothermia protocol in the survivors of cardiac arrest. Although the data have shown an improved neurologic end point in patients initially in ventricular fibrillation or pulseless ventricular tachycardia, there is still debate about whether patients initially in other rhythms would benefit from hypothermia after return of spontaneous circulation. This is a report of a 17-year-old male found to be in asystole after sustaining a TASER injury, who was treated with a hypothermia protocol after return of spontaneous circulation and left the hospital with intact neurologic function.

Electrical stimulation of the vagus nerve restores motility in an animal model of achalasia.

Esophageal peristalsis generally does not return to normal after surgical treatment of achalasia. Direct electrical stimulation of the vagus nerve is known to stimulate antegrade peristalsis in the normal esophagus; however, it is not known whether electrical stimulation will induce return of peristalsis once an achalasia-like disorder has been established. The objective of this study was to perform quantitive and qualitative measurements of motility during electrical stimulation of the vagal nerve in an animal model of achalasia.
