Multicenter Study Comparative Study
Improved predictions from a severity characterization of trauma (ASCOT) over Trauma and Injury Severity Score (TRISS): results of an independent evaluation.
In 1986, data from 25,000 major trauma outcome study patients were used to relate Trauma and Injury Severity Score (TRISS) values to survival probability. The resulting norms have been widely used. Motivated by TRISS limitations, A Severity Characterization of Trauma (ASCOT) was introduced in 1990. The objective of this study was to evaluate and compare TRISS and ASCOT probability predictions using carefully collected and independently reviewed data not used in the development of those norms. ⋯ In this age of health care decisions influenced by outcome evaluations, ASCOT's more precise description of anatomic injury and its improved calibration with actual outcomes argue for its adoption as the standard method for outcome prediction.

A series of 168 civilian cases of tangential gunshot wounds to the head is presented. Neurologic deficits on presentation were generally minimal. ⋯ Serious sequelae of tangential injuries are described even with patients who initially have no neurologic abnormality. We suggest that a CT scan is warranted in all cases of tangential gunshot wounds to the head.

The goal of this study was to describe the epidemiology, clinical presentation, diagnostic methods, and outcome in a large series of children with blunt cardiac injury (BCI). ⋯ Pediatric BCI is usually diagnosed in the context of severe multiple system trauma and is less commonly an isolated event. Because of the lack of a standard, various diagnostic tests are used in the diagnosis of BCI, and these tests rarely agree. In hospitalized pediatric patients with BCI, unanticipated complications are rare. Significant sequela, although uncommon, do occur and follow-up of children with BCI should be ensured.

Medial dissection of the aorta after blunt trauma is a rare occurrence. We report the case of a 79-year-old woman injured in a motor vehicle crash who suffered an acute DeBakey type I aortic dissection.

Scapulothoracic dissociation, although rare, causes significant morbidity and mortality by completely disrupting the attachments of the scapula to the axial skeleton with the skin remaining intact. The defining constellation of injuries is subclavian or axillary vascular disruption, lateral displacement of the scapula, separation of the clavicular articulations with or without fracture of the clavicle, and cervical nerve root avulsion or brachial plexus injury. Orthopedic stabilization, vascular repair, and brachial plexus exploration are mandatory. Above elbow amputation, either primarily or within 24 hours, is recommended for the flail extremity.
