Comparative Study
A stepwise logistic regression analysis of factors affecting morbidity and mortality after thoracic trauma: effect of epidural analgesia.
Rib fractures and other chest wall injuries can lead to weak ventilation, atelectasis, and even death. Whereas such injuries in young patients are usually well tolerated, relatively minor chest wall trauma can be serious in elderly patients. Epidural analgesia, by improving pain control and ventilatory function, might improve morbidity and mortality rates compared to other forms of analgesia. ⋯ In spite of more severe thoracic trauma in epidural patients as measured by the Abbreviated Injury Score for the chest (epidural = 3.3 +/- 0.1, IV/IM = 2.8 +/- 0.1; p less than 0.05) the use of epidural analgesia was an independent predictor of both decreased mortality (p = 0.0035) and a decreased incidence of pulmonary complications (p = 0.0088). Epidural analgesia has a positive effect on outcome in elderly trauma victims with chest wall injury and is useful in high-risk patients. Increased costs associated with epidural analgesia are minimal and are justified by improvements in outcome.

Early deaths from trauma are often caused by exsanguinating hemorrhage from injuries that appear "irreparable." We explored the limits of deep hypothermic circulatory arrest induced during hemorrhagic shock to enable repair of these injuries in a bloodless field. In 15 dogs, after 30 minutes of hemorrhagic shock (mean arterial pressure, 40 mm Hg), cardiopulmonary bypass (CPB) was used to cool to 15 degrees C in 13-37 minutes. After circulatory arrest of 60 (Group 1), 90 (Group 2), or 120 (Group 3) minutes, reperfusion and rewarming were accomplished by CPB. ⋯ After perfusion-fixation sacrifice, brain histopathologic damage scores correlated with insult time, as did ND scores. Deep hypothermia can allow 60-90 min of circulatory arrest with good neurologic recovery, even after a period of severe hemorrhagic shock. This technique may allow repair of otherwise lethal injuries and survival without brain damage.

A retrospective review of 114 solid organ donors over a 6-year period (1982-1987) was undertaken to identify problems in organ donor management and determine outcome of donated organs. Admission GCS was less than or equal to 4 in 84% of the donors. Complications included hypotension (81%), multiple transfusion requirements (63%), diabetes insipidus (53%), DIC (28%), arrhythmias (27%), cardiac arrest requiring CPR (25%), pulmonary edema (19%), hypoxia (11%), acidosis (11%), seizures (10%), and positive bacterial cultures (10%). ⋯ Reasons for failure of donated organs to be procured or transplanted included abnormal organ characteristics, lack of compatible recipients, unavailability of surgical teams, organ injury during procurement, intraoperative arrest, and anatomic limitations precluding multiple organ procurement. This study identifies characteristics of organ donors and common organ-threatening complications. Rapid and continuing resuscitation of clinically brain dead trauma victims is mandatory.(ABSTRACT TRUNCATED AT 250 WORDS)

The early recognition of life-threatening injury is paramount to the prompt initiation of appropriate care. This study assesses the importance of multiple rib fractures as a marker of severe injury in children. We analyzed physiologic, etiologic, and injury data for 2,080 children with blunt or penetrating trauma aged 0-14 years consecutively admitted to a Level I pediatric trauma center. ⋯ Although rib fractures are rare injuries in childhood, they are associated with a high risk of death. The risk of mortality increases with the number of ribs fractured. The combination of rib fractures and head injury was usually fatal.
