Human burn injury is associated with an inflammatory response and related hyperdynamic cardiovascular profile. Increased production of nitric oxide (NO), a potent endogenous vasodilator, has been reported in patients with inflammatory states, including sepsis, but not after trauma other than burns. We studied whether plasma levels of the stable byproducts of NO, nitrite (NO2-) and nitrate (NO3-), are increased in burn patients. ⋯ Human burn injury is associated with an increase in NO production. In this small-size study, NO production was not proportional to burn area, and seemed to be further enhanced in septic patients.

Authors presented their own experiences in treating 735 wounded in high-intensity combat zones in the territories of former Yugoslavia during 1991 to 1992. The mobile field hospital with surgical crews was situated 5 to 10 km from the front line, and its basic task had been continuous triage, immediate resuscitation with vital surgical aid, as well as organization of adequate primary and secondary air evacuation. ⋯ Mortality at this primary level, field hospital was 0.75% with primary immediate resuscitation and 1.9% with immediate evacuation. We concluded that immediate resuscitation with delayed transport had advantages, compared with fast evacuation of only the wounded.

Nonoperative management of a splenic tear in a Jehovah's Witness with hemophilia.
Splenic laceration, the most common visceral lesion following blunt abdominal trauma, can be treated in a nonoperative fashion in only a select group of stable patients with minimal injury. We report a unique case of life-threatening splenic trauma in a Jehovah's Witness with hemophilia that was successfully managed without surgery.

Since 1990, Florida has used a uniform set of eight triage criteria, known as the trauma scorecard, for triaging adult patients with trauma to state-approved trauma centers. If any one of the eight criteria are met, paramedics classify the patient as a "trauma alert" and transport to a state-approved trauma center. ⋯ Thus, the Florida Department of Health and Rehabilitative Services, Office of Emergency Medical Services initiated a research effort to assess the effectiveness of the state-adopted trauma triage criteria for adults, giving special attention to geriatric trauma. The results of the Florida Trauma Triage Study indicate that the eight triage criteria comprising the trauma scorecard produce unacceptable levels of undertriage in elderly patients (age 55 years or older) with life-threatening injuries.

Self-inflating bag-valve devices are commonly used for the ventilation of intubated patients, especially during resuscitation and transport. These devices are generally safe, but minor deviations in their recommended use can expose patients to airway pressures greater than 135 cm H2O. ⋯ We believe that this complication resulted from high airway pressures generated in the bag-valve device. The ability of the device in question to cause barotrauma was confirmed by bench-top measurements of the peak airway pressures generated by minor deviations from proper use of the device.
