Ventilator-associated pneumonia (PN) is difficult to distinguish from trauma-induced systemic inflammatory response syndrome (SIRS), especially in patients with multiple injuries. Previous work using bronchoscopy and quantitative cultures demonstrated significant bacterial growth in about one-third of patients with clinical evidence of PN. In this prospective study, antibiotic therapy for PN was based solely on quantitative bronchoalveolar lavage (BAL) cultures. ⋯ SIRS, which can mimic PN, is common in trauma patients. These entities can be distinguished by bronchoscopy with BAL. Basing antibiotic therapy solely on quantitative BAL cultures is efficacious in trauma patients.

Upper extremity injuries are commonly seen in the sport of in-line skating. The use of protective equipment, including wrist splints, has been advocated as a means to decrease both the incidence and severity of upper extremity injuries in this sport. We report on four cases of open forearm fractures in the in-line skaters that occurred adjacent to the proximal border of the wrist splints. ⋯ The splint and distal forearm may act as a single unit to convert the impact from the level of the wrist to a torque moment, with the fulcrum located at the proximal border of the splint. The energy from the fall is then dissipated by the fracturing of the forearm bones at this level. These cases suggest that the use of wrist splints may be associated with their own specific set of injury patterns.

The diagnosis and management of occult vascular injuries caused by penetrating proximity extremity trauma (PPET) remains controversial. Over 18 months, we prospectively screened 37 patients (43 lower extremities) with PPET for occult arterial and venous injuries using noninvasive studies (physical examination, ankle-brachial indices, color-flow duplex ultrasonography (CFD)) and angiography (arteriography, venography). Eight isolated, occult venous injuries were detected (incidence, 22%). ⋯ Major thromboembolic complications (pulmonary embolism, symptomatic deep vein thrombosis, venous claudication) occurred in 50% of the patients identified with femoral-popliteal vein injuries. Arterial injuries were detected in 4 of 42 (10%) extremities (arteriography, n = 3; CFD, n = 1) and were clinically benign. We conclude that following PPET, (1) isolated, occult venous injuries are common and are associated with significant complications and (2) CFD is useful for screening for occult venous injuries.

Three weeks after a shotgun wound to the chest and abdomen, a patient developed acute ureteral colic caused by a migrating shotgun pellet. The pellet passed spontaneously. A search of the literature revealed 25 similar cases of this unusual complication of missile injuries to the abdomen. ⋯ Cases involving bullets and shrapnel fragments usually have had long latent periods after the initial injury and required surgery to remove the obstructing projectile. In contrast, cases of "buckshot colic" from shotgun pellets present earlier and often resolve with spontaneous passage of the pellet. The following report illustrates how conservative management can be successful in cases of "buckshot colic."

Exclusion of aortic tear in the unstable trauma patient: the utility of transesophageal echocardiography.
The goal of this study was to investigate the value of biplanar transesophageal echocardiography (TEE) as a screening tool for aortic tear in unstable trauma patients. ⋯ The TEE procedure is valuable in identifying aortic injury in high-risk trauma patients who are too unstable to undergo transport to the aortography suite.
