Spent bullets and their injuries: the result of firing weapons into the sky.
People often celebrate holidays by firing guns into the air without realizing that this can cause serious injury or death. The present study identified 118 patients treated since 1985 who were hit with spent bullets. ⋯ The mortality rate was 32%, which is significantly higher than for all gunshot wound victims in general seen at the same medical center. Laws have been enacted to help prevent people shooting into the sky, but more education and enforcement are required to prevent these serious and preventable injuries.

The incidence of rib fractures secondary to trauma has not been clearly reported. Of the 7147 patients seen by our trauma service from January 1987 to June 1992, 711 (10%) had rib fractures. ⋯ Thirty-five percent of the patients required discharge to an extended care facility and 35% developed a pulmonary complication. We conclude that rib fractures are a marker of severe injury in which (1) 12% will die because of their injuries, (2) more than 90% will have associated injuries, (3) one half will require operative and ICU care, (4) one third will develop pulmonary complications, and (5) one third will require discharge to an extended care facility.

Seventy-two open fractures associated with arterial injury requiring vascular repair (Gustilo type IIIC injuries) were treated at the University of Louisville from May 1983 and through 1992. The involved anatomic areas were the humerus (four), forearm (ten), femur (eight), tibia (31), ankle (ten), and foot (nine). Fracture management consisted of careful débridement, wound irrigation, fasciotomy, and fracture stabilization. ⋯ The wound infection rate was 13.9% (10 of 72) and the rate for osteomyelitis was 4.2% (3 of 72). The local use of the antibiotic bead chains was of significant benefit in lowering infectious complications. Primary coverage of soft-tissue defects with free tissue transfer had an infection rate of 66%; temporary wound coverage with the "antibiotic bead pouch" technique until wound closure can be obtained in a sterile and viable environment appears to be a better option.

To evaluate the relative accuracy of right ventricular end-diastolic volume index (RVEDVI) and pulmonary artery wedge pressure (PAWP) for determining cardiac preload. ⋯ The RVEDVI more accurately predicted preload recruitable increases in CI than did the PAWP.

Routine admission laboratory test protocols in injured patients are costly and involve excessive phlebotomy and turnaround time. The purpose of this prospective study was to evaluate the utility of (1) a microanalyzer, NOVA-SP5 (which provides rapid results on minimal blood volume), and (2) each component of our standard laboratory test battery. ⋯ Microanalysis is accurate, expedient, conserves blood, and is sufficient for evaluation of most trauma patients. Those with hypertension, diabetes, or severe head trauma may require additional testing. Routine use of this technique could reduce cost substantially ($16,000/100 patients). The role of microanalysis in follow-up laboratory evaluation of injured patients remains to be elucidated.
