This retrospective study of 100 consecutive patients with inhalation injury documents that adult respiratory distress syndrome (ARDS) and pneumonia are common complications. Pulmonary complications cause or directly contribute to death in 77% of patients with combined inhalation and cutaneous burn injury. Additionally, the high fluid requirements of these patients worsens their pulmonary injury and is associated with adverse outcome. ⋯ An abnormal chest roentgenogram in the first 48 hours after injury is also associated with death. The development of ARDS is predicted by the actual volume of fluid resuscitation, despite normal pulmonary wedge pressure or normal central venous pressure reflecting increased microvascular permeability. These findings indicate a need for reevaluation of fluid resuscitation of patients with inhalation injury.

The aim of this study was to determine (1) if internal fixation was associated with a high amputation rate in patients with femur fracture and vascular injury; and (2) if patients who underwent internal fixation before vascular repair had a higher amputation rate. ⋯ In these patients, poor outcome is associated with severe leg injury, (with a Mangled Extremity Severity Score of > or = 6). Internal fixation can be safely used, and skeletal stabilization can be safely performed before vascular repair. If ischemic time is prolonged, vascular shunts should be used until skeletal stabilization is completed.

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.

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.
