The Los Angeles County-University of Southern California (LAC-USC) Medical Center, a level I trauma center, has experienced a rapidly increasing incidence of gunshot wounds (GSWs). We sought to enumerate the annual monetary costs and medical consequences of thoracoabdominal gunshot wounds in the epicenter of urban violence. A consecutive series of patients admitted from September 1, 1989 to August 31, 1990 was studied. ⋯ Annual medical cost of all admissions including rehabilitation, however, could be as great as $12 million for the Medical Center and $53 million for the County of Los Angeles. Thirty percent of patients had MediCal insurance. Payment could not be recovered from another 57% of patients.(ABSTRACT TRUNCATED AT 250 WORDS)

A sample of 360 severely injured patients was selected from a cohort of 8007 trauma victims followed prospectively from the time of injury to death or discharge. A case referent study was used to test the association between on-site care, total prehospital time, and level of care at the receiving hospital with short-term survival. ⋯ Total prehospital time over 60 minutes was associated with a statistically significant adjusted relative odds of dying (OR = 3.0). The results of this study support the need for regionalization of trauma care and fail to show a benefit associated with ALS.

The nutritional needs of critically ill septic patients or patients with multiple injuries are often difficult to estimate. Indirect calorimetry can simply and accurately determine individual caloric and nutritional needs, especially in cases of critically ill patients with complicated injuries. This prospective study compared the measured energy expenditures of 30 patients using indirect calorimetry with their predicted basal energy expenditure according to the Harris-Benedict equation, or their calculated energy expenditure derived from basal energy expenditure times, an activity factor, and a stress factor. ⋯ Their stress factors could be modified as "0.97 + 0.0125 x SSS" to get a more accurate Harris-Benedict calculation. For the 15 patients with multiple injuries in whom the measured energy expenditure per kilogram was 34.9 +/- 1.6 kcal/kg, the ISS offered the best correlation with measured energy expenditure per kilogram (r = 0.84, Y = -31.47 +/- 1.73 X). Their stress factors could be modified as "1.04 + 0.0077 x ISS" to get a more accurate Harris-Benedict calculation.

As triage and resuscitation protocols evolve, it is critical to determine the major extracranial variables influencing outcome in the setting of severe head injury. We prospectively studied the outcome from severe head injury (GCS score < or = 8) in 717 cases in the Traumatic Coma Data Bank. We investigated the impact on outcome of hypotension (SBP < 90 mm Hg) and hypoxia (Pao2 < or = 60 mm Hg or apnea or cyanosis in the field) as secondary brain insults, occurring from injury through resuscitation. ⋯ Hypoxia and hypotension are common and detrimental secondary brain insults. Hypotension, particularly, is a major determinant of outcome from severe head injury. Resuscitation protocols for brain injured patients should assiduously avoid hypovolemic shock on an absolute basis.

Major blood loss occurs with excisional therapy of burns. To our knowledge no studies have quantitated blood loss in pediatric patients. This prospective study was performed to analyze blood loss in a pediatric burn population undergoing excision and grafting. ⋯ Assessment of losses by age and depth of wound, patient age, and anatomic site showed no differences between these groups. Tourniquets lowered intraoperative losses but had no effect on overall losses. The value of knowing blood losses precisely is evaluated in terms of efficiency of ordering blood.
