Comparative Study
A prospective study of 91 patients undergoing both computed tomography and peritoneal lavage following blunt abdominal trauma.
Recent reports comparing computed tomography of the abdomen (CTA) and diagnostic peritoneal lavage (DPL) following trauma have been contradictory. A 10-month prospective study was conducted at our trauma center comparing both methods. Criteria for entry into the study included suspected blunt abdominal trauma without indication for immediate laparotomy, with either equivocal abdominal examination, diminished sensorium, or neurologic deficit. ⋯ The results of CTA and DPL were compared to the findings at laparotomy or the clinical course of those not explored. The sensitivity, specificity, and accuracy for initial CTA were 60%, 100%, and 91%; for review CTA 85%, 100%, and 97%; for DPL 90%, 100%, and 98%. We conclude that: even with experienced examiners, CTA offers no diagnostic advantage over DPL in blunt trauma; because of relative costs, we do not recommend the routine application of CTA; CTA is a reliable alternative when circumstances prevent the performance of DPL.

Twenty-one children admitted between December 1981 and May 1985, with greater than 80% total body surface area burn (TBSAB), underwent total excision and grafting of all of their wounds within 72 hours of injury. Twelve survivors (with an average TBSAB of 89%, 82% third degree) were studied in detail describing the length of hospital stay (77 +/- 10 days), number of operative procedures (7.8 +/- 0.8), total blood loss (12 +/- 2 blood volumes), the number of patients who experienced septic episodes (three), the number of patients who required amputation (four), range of motion, degree of scarring, ability to perform daily activities, and psychological adjustment. ⋯ One third of the children had excessive fear, regression, and neurotic and somatic complaints, but all of them showed remarkable energy in adapting to their disabilities. We conclude that the final outcome, for these patients, can only be assessed as they achieve late adolescence and young adulthood.

Randomized Controlled Trial Clinical Trial
The effects of inflation of antishock trousers on hemodynamics in normovolemic subjects.
Antishock trousers may maintain mean arterial pressure in trauma patients by increasing central blood volume and cardiac output. Hemodynamics, end-diastolic volume, stroke volume, cardiac output, and blood pressure were recorded in eight supine, healthy men in antishock trousers using two-dimensional echocardiography. Two inflation protocols were used. ⋯ The study shows that the antishock trousers alter several hemodynamic parameters. With lower inflation pressures, antishock trousers cause an increase in arterial pressure by increasing peripheral resistance. At higher inflation pressures, the antishock trousers increase cardiac output and as the cardiovascular system adjusts, maintain the pressure by increasing peripheral resistance.

Ten patients with blunt heart rupture arrived in our emergency center alive during an 11-year period ending in 1984. Ages ranged from 19 to 65 years (mean, 35), and seven patients were male. Six patients presented with tamponade, three with hemorrhagic shock, and one with combined symptoms. ⋯ Seven patients survived. Three deaths were due to irreversible hemorrhagic shock, two secondary to heart injury, and one from an associated liver injury. Prompt pericardial window with subsequent median sternotomy was successful for patients presenting with tamponade and immediate thoracotomy for those bleeding into a pleural cavity.

We present two cases of delayed, massive, life-threatening hemothorax due to intercostal hemorrhage in association with fractured ribs and severe blunt chest trauma (SBCT), a combination we have not seen described in the literature. Blunt chest trauma is not benign. Significant intrathoracic injuries are frequent although usually not life threatening. ⋯ However, rapid blood loss requires immediate open thoracotomy and surgical attention. Several days of observation in hospital may be required for patients with SBCT and fractured ribs even without any other obvious intra- or extra-thoracic injuries. Vigorous activity or chest physical therapy may be dangerous during the first several days after the injury.
