Emergency surgery in patients with post-traumatic myocardial contusion.
Little information concerning the prognostic and functional significance of post-traumatic myocardial contusion appears to exist. During a 10-month period, 19 patients with major blunt thoracic trauma were diagnosed as having myocardial contusion using clinical findings, serial ECG and CPK-MB isoenzyme determinations, and biventricular radionuclide angiocardiography (RA). All patients had associated thoracic and extrathoracic injuries. ECG and RA were useful and complementary tests, detecting abnormalities in 90% and 47% of patients, respectively. Only one patient had an abnormally elevated CPK-MB. All patients required operative treatment for associated injuries, 15 (79%) on the day of admission. Eleven patients required perioperative cardiac inotropic support and one needed IABP. No late complications were attributable to the cardiac contusions per se; no patients died. Emergency surgery for associated injuries in patients with myocardial contusion can be safely performed using hemodynamic monitoring to guide cardiac inotropic support measures. Myocardial contusion does not constitute an absolute contraindication to necessary operations in polytraumatized patients.
