Warming plastic bags containing intravenous solutions in a microwave oven (MWO) raised the temperature from 18 degrees C to an average of 34.1 degrees, 40.2 degrees, and 42.8 degrees C when treated for 120, 150, and 160 seconds, respectively. Fluids at 18 degrees C, when passed through a blood warmer, resulted in temperatures at the distal end (DE) of about 27 degrees C; but if the bags were priorly warmed to 42 degrees C, fluids arrived at the DE at a temperature of about 30 degrees C. Fluids heated by MWO to 42 degrees C through a single short tubing 180 cm long arrived at the DE at a temperature of 33.7 degrees C. ⋯ One group of 19 patients undergoing repair of injuries to extremities received infusions warmed by MWO to 42 degrees, while other groups received them at about 20 degrees. After an initial fall, average temperature in the former tended toward normal levels while in the latter, body temperature declined. The simple expedience of MWO warming of the bags to 42 degrees C, and flowing through shorter administration tubing, appears to ameliorate this complication and in some cases prevents it.

Lumbar puncture has been in widespread clinical use for nearly a century. It is used in emergency medicine primarily as a tool for the diagnosis of meningoencephalitis and subarachnoid hemorrhage. The development of computed tomography has changed the position that lumbar puncture has held in the diagnostic sequence of a number of clinical entities. ⋯ Meningitis has been found to follow lumbar puncture in children with bacteremia. The lumbar puncture is a useful test for providing information regarding the cellular, chemical, and microbiologic composition of the CSF. Fluid obtained should be evaluated for cell count, Gram's stain, bacterial culture, glucose and protein levels, and other tests as clinically indicated.

A 39-year-old male arrived in the emergency department with multiple stab wounds to the chest. A pneumopericardium was present on initial chest x-ray study. ⋯ All parameters improved following removal of 100 cc of air by pericardiocentesis. The etiology, diagnosis, pathophysiology, and treatment of tension pneumopericardium are discussed.

Poisoning by blue-green algae occurs after an algal "bloom" caused by warm weather and algal concentration. On death or disintegration, the algae release liver toxins and neurotoxins (fast death factor). Although deaths are common in animal exposures, human exposures have been limited to various allergic reactions, mild liver enzyme elevation, and gastroenteritis. A case of animal deaths and its relationship to human exposures is discussed.

Child maltreatment continues to be one of the most common and most difficult problems seen in the emergency room. An early estimate indicated that up to 10% of children under age 6 seen in emergency departments have some form of nonaccidental injury. Recent data suggest that approximately 1% of the child population are victims of maltreatment each year. ⋯ This article provides a review of the various forms of maltreatment, with emphasis on the key points involved in the history, physical examination, and management. The protocol for evaluating maltreatment from the North Carolina Memorial Hospital is presented. This framework will aid the physician in the crucial first step of identifying maltreatment, which, along with diligent follow-up and the assistance of the available social services, offers the best hope for further prevention.
