Reappraisal of emergency room thoracotomy in a changing environment.

The efficacy of resuscitative emergency room thoracotomy (ERT), particularly in blunt injury, has been questioned. Wide application of the procedure may not be cost effective. The risk of exposure and lethal infection to medical personnel during ERT is considerable. For the past decade, the policy at this institution has been to perform ERT on all moribund patients sustaining penetrating torso injury and all patients sustaining blunt injury with any evidence of cardiac electrical activity. To evaluate whether such a liberal policy is currently justified, the charts of all patients undergoing ERT over a 4-year period were reviewed. One hundred twelve patients underwent ERT; 24 (21%) sustained penetrating injury, 88 (79%) blunt injury. The overall survival rate was 1.8%. Penetrating injury had a 4.2% survival and blunt injury 1.1%. No patients with CPR initiated at the scene and required throughout transport survived. In those patients with both blood pressure and spontaneous respirations present in the field, survival rate was 11.8%. Survival rate in patients manifesting sinus rhythm or ventricular fibrillation upon arrival at the ER was 6.4%. No survivors were noted among patients coming to the hospital with an idioventricular rhythm or asystole. The total hospital charges for patients undergoing ERT exceeded reimbursement by $59,565. Screening for HIV and hepatitis could be documented in only two patients; both were negative. Liberal performance of ERT has dismal results, incurs monetary loss, and affords a greater potential for exposure to lethal infection. Emergency room thoracotomy is justified only when vital signs or a resuscitatible cardiac rhythm are present in the field or ER and deteriorate shortly before thoracotomy.(ABSTRACT TRUNCATED AT 250 WORDS)
