Computerized tomographic (CT) scanning for blunt abdominal trauma has focused on initial emergency department evaluation. At our institution, CT scanning is often used on a delayed basis for unexplained drops in hematocrit, investigation of bony injuries, or subtle abdominal findings. We reviewed 268 such scans. ⋯ There was no difference in the pre-scan hematocrit drop in patients with normal scans (6.6%), positive scans (6.8%), and those who were explored (6.4%). There was one false positive (0.4%) and two false negative scans (0.8%). Conclusions. (1) A significant number of occult injuries, some life threatening, are detected by delayed CT scans. (2) Hematocrit drop under observation is not a good predictor of occult intra-abdominal injury. (3) Delayed CT scanning for occult abdominal injury is cost effective.

We report the case of a 14-month-old child with hydrofluoric acid burns who suffered cardiac arrest in association with profound hypocalcemia and hyperfluoridemia. Successful treatment included topical, subeschar, and intravenous calcium gluconate administration.

We report the case of a 27-year-old patient with blunt thoracic trauma in whom transesophageal echocardiography enabled an early diagnosis of severe myocardial contusion. Conventional mechanical ventilation dramatically enhanced cardiogenic shock because of myocardial contusion, requiring increasing doses of catecholamine. High-frequency jet ventilation produced an immediate improvement in hemodynamic status, permitting a decrease in catecholamine administration.

Survival determinants were examined in patients undergoing ERT-PCI who were admitted to the Surgical Intensive Care Unit (SICU) between January 1, 1982 and August 1, 1991. Twenty-one of 290 patients undergoing ERT-PCI (aged 14-36 years) were admitted to the SICU. Of the 21, nine survived to discharge with normal neurologic function. ⋯ All survivors had vital signs either in the field or on ER arrival. Patients with penetrating chest wounds without vital signs in the field who do not recover vital signs by hospital arrival do not benefit from emergency room thoracotomy. Evidence of mentation in the field or on arrival may predict ultimate neurologic outcome of survivors.

The baseball bat, according to Baltimore City police crime statistics, is a commonly used weapon. To assess the severity of injuries inflicted by this modern-day club, we retrospectively reviewed 75 charts of patients treated at the University of Maryland Medical Systems Hospital for baseball bat injuries from January 1990 through July 1991. ⋯ In our series, the history of loss of consciousness and the Glasgow Coma Scale score failed to reliably identify the patients with serious injuries. Seventeen percent of our patients with intracranial hemorrhages had both a negative or uncertain history of loss of consciousness and a normal Glasgow Coma Scale score on arrival.
