Emergency department deaths.

This study reviews 186 deaths resulting from trauma in a 2-year period in the Charity Hospital of Louisiana at New Orleans Accident Room in order to evaluate problems in prehospital and hospital resuscitative care. All subjects underwent autopsy, and only six were found to have injuries compatible with survival. Three of these were late arrivals (by transfer or self-imposed delay) and died of protracted hemorrhage. Only three deaths occurring in the Emergency Department itself were found to have been potentially preventable. The important factors in maximizing survival of trauma patients remain rapid transport; immediate, appropriate, rapid evaluation; and quick diagnosis, resuscitation, and definitive therapy. These require a well-trained emergency medical ambulance service delivering patients quickly to a hospital designed to handle trauma patients. One person, preferably a general surgeon with trauma experience, should supervise and monitor the patient continually until the resuscitation phase and all diagnostic tests are completed and definitive therapy is initiated.

Nutritional considerations in the critically ill.

The total care of the critically ill patient must include attention to his nutritional status from the onset of illness. The essential role of protein in body functions must be stressed; unfortunately, it is this essential compartment that will be called upon for gluconeogenesis in stress or starvation. Simple technics of bedside nutritional assessment have been developed and should be familiar to all those who deal with critically ill patients. The multiple technics of optimal nutritional support should become a standard component of the therapeutic armamentarium of those who provide intensive care. The goal must always be to use the GI tract whenever possible, avoiding the numerous complications associated with intravenous nutrition. Care must be taken to avoid CO2 overload of an embarrassed respiratory system by the nutritional support. Whether nutritional or pulmonary support should take priority can usually be resolved by a team approach toward the patient. It is hoped that this superficial review of nutritional support will stimulate the desire for further knowledge of this rapidly changing and interesting aspect of critical care.

Computer simulation as a method for evaluating the copper sulfate test for hemoglobin in diverse populations.

The copper sulfate hemoglobin screening method was separately evaluated for three local population groups which do not conform to accepted normal standards of hemoglobin and/or plasma specific gravity (SG). This was carried out by a computer which simulated the distribution of plasma specific gravity and hemoglobin levels in random samples of blood donors. Simulations of 1,000 were carried out for males and for females in each of the three main population groups in Natal (Caucasians, Negroes and Asians). These were compared with a simulation of hypothetical normal subjects whose hemoglobin and plasma SG conformed to accepted standards. Variations in accuracy, relating to differences in plasma specific gravity and in hemoglobin, were demonstrated. Acceptances of donors who should be rejected (Type II errors) were most common in Negroes, but did not occur in the normal group. Type II errors did not occur in males with hemoglobin levels below 12.5 gm/dl or in females under 11.5 gm/dl. Erroneous rejections of prospective donors who, in fact, satisfied the criterion of acceptance (Type I errors) occurred in all groups, but were fewest in the normal group.
