Survival after massive transfusions exceeding four blood volumes in patients with blunt injuries.
The authors' experience with 29 patients with blunt injuries who sustained massive transfusions exceeding four blood volumes in the initial posttraumatic 12 hours was reviewed. The overall mortality was 62 per cent. Only one patient survived when the amount of transfusions exceeded 50 units. ⋯ Of those who died, seven died from brain injury, six from multiple organ failure (MOF), and five from uncontrollable bleeding. Initial shock was observed in 55 per cent of patients. The high mortality of patients with massive transfusions and MOF related to the duration of shock strongly promote the importance of initial volume resuscitation.

The utility of cardiac evaluation in the hemodynamically stable patient with suspected myocardial contusion.
Myocardial contusion following isolated blunt thoracic trauma (BTT) remains a diagnostic and therapeutic dilemma. To identify the presence of cardiac abnormality following BTT, 123 hemodynamically stable patients were prospectively evaluated with serial electrocardiograms (ECG) and cardiac enzymes (total CPK and CPK-MB). Gated cardiac radionuclide angiography (MUGA) scans were performed within 48 hours following admission. ⋯ MUGA scan was abnormal (right ventricular ejection fraction less than 40 per cent and/or wall motion abnormality) in 12 patients (19%). Eight patients with MUGA scan abnormality had normal ECG and/or normal total CPK, CPK-MB values. Evaluation of all patients up to six months revealed no mortality, malignant arrhythmias, or cardiac failure.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical indications for cervical spine radiographs in alert trauma patients.
Cervical spine fracture/dislocation is a potentially devastating injury that may be clinically difficult to diagnose. Therefore, a vast majority of trauma patients undergo cervical spine X rays when only a relatively small number of them will actually have a cervical spine injury. Because of the costly overuse of radiography, studies have been undertaken to define high yield criteria for evaluation of patients. ⋯ Although occult or painless cervical spine injuries have been reported in the literature, a careful review of these cases revealed that these injuries were not truly asymptomatic. Our study suggests that selected patients can be excluded from radiologic evaluation of the cervical spine. However, large prospective studies are needed to validate this finding.
