The results of 163 patients (49 SWs, 85 GSWs, 29 blunt trauma) who had resuscitative thoracotomy in the emergency room (ERT) were reviewed to reassess the indications for the procedure. The Revised Trauma Score (RTS) of the patients ranged from 0 to 3 in 138, 4 to 8 in 21, and greater than 8 in four. No patient with blunt trauma survived. ⋯ Two of the five patients (40%) with extremity vascular injuries survived after ERT was successful in restoring a cardiac rhythm. These data suggest that in patients without vital signs, ERT "directed" at potential cardiac injury based on thoracic penetration is an important prognostic prerequisite for survival. Emergency room thoracotomy is not beneficial in blunt trauma and its role in penetrating abdominal injuries remains unproven.

Criteria for defining the major trauma patient have been specified by physicians using Injury Patient Management Categories (PMCs), a computerized classification that can be used effectively with routinely collected discharge abstract data from non-trauma center hospitals as well as trauma centers. These criteria for major trauma not only include the more severe and complex single injuries, but also include criteria for identifying combinations of injuries that require tertiary level care. ⋯ In addition, unlike other measures that are generally limited to registries, PMC tertiary patient criteria differentiate major trauma patients at both trauma centers and non-trauma centers without additional data collection. Using this method thus facilitates trauma systems evaluation and patient outcome assessment.

Continuous arteriovenous rewarming: report of a new technique for treating hypothermia.
Survival is rare after major trauma if core temperature falls below 32 degrees C. Available rewarming methods are often ineffective. We utilized arterial and venous catheters to create a circulatory fistula through the heating mechanism of a modified commercially available counter-current fluid warmer to achieve simple, rapid extracorporeal rewarming.

During a 48-month period, 2,248 children (aged less than 15 years) were consecutively admitted to a regional pediatric trauma center with blunt trauma (ICD-9-CM code greater than or equal to 800). Fifty-four children (2.4%) had injury to the pelvic circle, as diagnosed by radiographic examination; 13 of these children had concomitant abdominal or genitourinary (GU) injury. Contingency table analysis and stepwise logistic regression were used to determine the best predictors of abdominal injury. ⋯ Ten children (19%) had multiple pelvic fractures. Location of fracture was strongly associated with the probability of abdominal injury: 80% of children with multiple pelvic fractures had concomitant abdominal or GU injury, compared with 33% with fracture of the ilium or pelvic rim, and 6% with isolated pubic fractures (p less than 0.001). The variables that best predicted abdominal or GU injury using a backward-elimination, stepwise logistic model were the presence of multiple pelvic fractures (p less than 0.002) and unweighted Revised Trauma Score (p less than 0.05); age of child, systolic blood pressure, respiration rate, Glasgow Coma Scale score, and mechanism of injury were not predictive.(ABSTRACT TRUNCATED AT 250 WORDS)
