The records of 57 patients presenting with flail chest injury from 1981 through 1987 were reviewed to determine factors affecting morbidity and mortality. Fifteen patients (26%) had 8+ rib fractures with a unilateral flail and seven (12%) had multiple rib fractures with a bilateral flail. Thirty-two (56%) had moderate-severe pulmonary contusions and 44 (77%) required chest tubes for hemo-pneumothorax. ⋯ An adverse outcome occurred in 15 (28%); nine required ventilatory assistance greater than or equal to 14 days and six died of sepsis with pneumonia. The main factors associated with an adverse outcome were: an ISS greater than or equal to 31 (p less than 0.001), moderate-severe associated injuries (p less than 0.001), and blood transfusions (p less than 0.005). Although the primary determinants of an adverse outcome were the associated injuries and blood loss, a bilateral flail (p less than 0.01) and age greater than or equal to 50 years (p less than 0.02) were contributing factors.

To assess patterns of pediatric trauma triage and patient transfer to the pediatric trauma centers, the records of 1,307 patients 14 years old or less who were admitted or died during resuscitation at eight Level II Trauma Centers from January 1987 through December 1988 were reviewed retrospectively. Cases were analyzed according to the following criteria: age, diagnosis, mechanism of injury, admitting service, pediatric trauma score (PTS), length of stay in the intensive care unit (ICU) and in the hospital, and outcome. Forty-three patients were transferred to pediatric trauma centers based on local criteria. ⋯ Two hundred fifty-eight patients (19.7%) required ICU care for an average length of stay of 2.86 days. Twenty-four patients (1.8%) died; all 24 had a PTS less than or equal to 8. In comparing the data to the guidelines in Appendix J of the American College of Surgeons' Hospital and Prehospital Resources for Optimal Trauma Care of the Injured Patient for transfer to a Level I Pediatric Trauma Center, we found that children with a PTS greater than 8 and who either require ICU care and/or have altered states of consciousness can safely be treated in the adult ICU of a Level II Trauma Center.

Inhalation injury, present in approximately one third of burned patients treated at burn centers, increases mortality by a maximum of 20% in relation to age and extent of burn. The development of animal models of inhalation injury has made possible the identification of both the airway and vascular responses evoked by smoke inhalation. ⋯ Pharmacologic agents give promise of ameliorating the deleterious changes of the vasculature. The recent advances in understanding inhalation injury have identified the research needed to further improve patient salvage.

We evaluated a technique for treating hypothermia that uses extracorporeal circulation but does not require heparin or pump assistance. Hypothermia to 29.5 degrees C was induced in eight anesthetized dogs, and thermistors placed in the pulmonary artery, liver, bladder, esophagus, rectum, muscle, and skin. Four experimental animals were rewarmed by creating a fistula which connected arterial and venous femoral lines to an interposed counter-current heat exchanger. ⋯ Haptoglobin, platelet, fibrinogen, and fibrin split product levels were unaffected. Continuous arteriovenous rewarming (CAVR) improved T, CO, BT, and coagulation profile faster than any method yet reported not requiring heparin or cardiac bypass. The application of CAVR in post-traumatic hypothermia warrants further investigation.

Case Reports
Pediatric blunt liver injury and coagulopathy managed with packs and a silo: case report.
Packing the abdomen can be lifesaving when severe hepatic trauma is complicated by refractory hypothermia, coagulopathy, and continuing hemorrhage requiring large-volume transfusion. This report describes the successful use of abdominal packs and a modified silo in a child following blunt liver injury.
