Although scores and other prehospital triage schema effectively identify injured patients who will benefit from trauma center care, those tools are relatively nonspecific. One consequence is overtriage--transport of less severely injured patients to trauma centers--with resulting expenditure of scarce resources on patients who do not benefit from an emergent and intensive response. We developed a tool that, during the prehospital phase, can sort inner-city trauma victims into those who will require ICU/OR services and those who will not. ⋯ Based on our initial experience with the two-tier response, the sorting criteria were revised and refined. The sensitivity of the current version of the two-tier criteria for predicting which trauma patients will require ICU/OR services during the first 24 hours of hospitalization approaches 95% (excluding misapplications of the tool) while avoiding urgent trauma team mobilization in 57% of patients triaged to our trauma center. Two-tiered trauma responses appear to be safe and may represent an important strategy for more effective distribution of increasingly scarce and costly resources.

The results of 111 acute below-knee amputations in war wounded were reviewed. The majority of the patients were wounded by exploding mines. The amputation stumps were not closed primarily but secondarily after an average of 6.4 days. ⋯ After delayed primary closure 84% of the stumps healed without problems. The best results were obtained when the stump closure was performed within 1 week after the amputation. No cases of gas gangrene or tetanus were encountered.

A large number of laboratory tests are often ordered in the management of acutely burned patients. Administration of large volumes of fluid and frequent ventilator changes prompt many facilities to utilize ordering protocols. Forty-five consecutive acutely burned pediatric patients with burns measuring 25% or more of total body surface area (TBSA) sustained within 24 hours before admission were reviewed. ⋯ Of the four unexpected critical values obtained, two would have been picked up by our present standard noninvasive monitors. Six percent of estimated blood volume was used to perform laboratory tests. These results demonstrate that significant abnormal laboratory values are uncommon even in severely injured pediatric burn patients and that the ordering of these tests should be individualized based on patient examination and the use of noninvasive monitoring.

A retrospective review of 756 blunt trauma cases at a level I trauma center was conducted to determine the role of thoracolumbar (TL) spine roentgenograms in the management of asymptomatic patients. Thoracolumbar spine films were obtained on 106 patients. The charts from 99 patients were available for thorough review. ⋯ Of the 20 patients in whom the clinical examination was equivocal, one (5%) had radiographic evidence of TL spine injury. We conclude that physical examination is reliable for assessing the TL spine, and that in the absence of clinical evidence of injury, TL spine films are unnecessary. In patients with equivocal examinations, TL spine films should be obtained because 7% (one of 15) of the injuries were identified in this group.

In resuscitation from hemorrhagic shock, very small volumes of hypertonic saline (HS) improve blood pressure while reducing intracranial pressure and edema formation. The effects of hypertonic resuscitation fluids and hypernatremia on electrophysiologic brain function have not been studied. The present study was done in two parts. ⋯ We next examined the effects on the FEP of hypernatremia and hyperosmolarity produced by two different hyperosmotic fluids. Over a 1-hour period, 16 mL/kg HS (n = 8), 16 mL/kg IsoSal (4.5% saline, 5.9% glucose, 6.4% mixed amino acids; n = 8), or 40 mL/kg LR (n = 8) was infused into normovolemic rats. Plasma sodium levels increased in both hyperosmotic groups (baseline = 145.2 +/- 0.7 mEq/L; after infusion, HS = 202.4 +/- 9.8 mEq/L, IsoSal = 163.3 +/- 4.2 mEq/L; p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
