There were 225 patients with penetrating neck wounds admitted over a 4-year period. Mechanism of injury included stab wounds in 59%, gunshot wounds in 32%, and shotgun wounds in 9%. Location of injury was Zone 1, 16%, Zone 2, 42%, Zone 3, 18%, posterior triangle, 12%, and multiple, 12%. ⋯ There were no missed injuries in Groups 4 or 5. Two missed esophageal injuries occurred in Group 2, and a missed carotid injury occurred in Group 3. The following guidelines for management have resulted. 1) Unstable patients require immediate exploration. 2) Stable patients with equivocal physical findings can be managed according to results of esophageal examination and angiography. 3) Patients with low probability of injury due to location and clinical presentation can be observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Field triage of injured patients has the objective of rapid identification of that 5-10% with injuries serious enough to pose a risk to life. The process requires not only the identification of patients with abnormal physiology, but also those whose physiology is normal despite the fact that significant anatomic injury may exist. ⋯ The amount of vehicle damage observed with these velocity changes was found to be 20 inches of crush in direct frontal collisions, 28 inches of crush in offset frontal collisions, and 15 inches of damage in side impacts. Incorporating these findings into triage of trauma patients who exhibit normal vital signs at the accident scene may provide a more structured basis for field triage.

Two hundred fifty consecutive children hospitalized with severe injuries (at least one injury with an Abbreviated Injury Score [AIS] greater than or equal to 4 or two or more injuries with AIS scores greater than or equal to 2) were studied to determine their functional status at discharge and 6 months later using questions from the RAND Health Insurance Study (HIS) and the Glasgow Outcome Scale (GOS). Of the 217 surviving patients, 190 (88%) had one or more functional limitations by the HIS scale at discharge. Ten (5%) were in a vegetative state, 40 (18%) severely disabled, 97 (45%) moderately disabled, and 70 (32%) healthy by the GOS. ⋯ Seven (4%) were in a vegetative state, 17 (11%) severely disabled, 50 (32%) moderately disabled, and 82 (53%) healthy by the GOS. A substantial proportion of the whole group of children hospitalized for the treatment of severe injuries had ongoing physical disabilities that limited their participation in normal activities 6 months after they were discharged. This suggests a need for greater emphasis on the rehabilitation of pediatric trauma patients.

Case Reports
Coverage of acute vascular injuries of the axilla and groin with transposition muscle flaps: case reports.
Acute axillary or groin vascular injuries caused by farm machinery or shotgun blasts are often associated with extensive soft-tissue loss. Coverage of the repaired blood vessels with healthy tissue is necessary to avoid infection, desiccation, pseudoaneurysm, and rupture. Adjacent muscles are not always available to rotate for coverage, due to unacceptable functional loss, or injury to the principal vascular pedicle. ⋯ Followup ranging from 9 months to 5 years revealed no vascular failure or soft-tissue complications. We conclude that coverage of vascular repairs and soft-tissue defects with viable muscle is necessary in cases of extensive injury. Adjacent muscle is preferred for coverage, but when this is unavailable, coverage can still be achieved using more proximally pedicled muscles of the trunk.

Not every patient with a penetrating stab wound of the abdomen requires laparotomy. This report evaluates use of computerized tomographic (CT) scan in assessment of stable asymptomatic patients, with penetrating abdominal stab wounds, as an indicator of the necessity of abdominal exploration. In a prospective study, 50 patients with abdominal stab wounds were treated successfully with observation only, after admission abdominal CT scan interpretation was negative for pathology in 45 patients. ⋯ Of these 28 patients, 22 had correct CT scan findings verified by laparotomy, three were false positive for intra-abdominal injury resulting in negative explorations, and three patients had such nonspecific findings as fluid or air in the abdomen incompatible with precise organ injury identification. Our study shows that CT scan in patients with abdominal stab wounds identifies solid organ injury with great specificity and sensitivity, evaluates the retroperitoneum well, and detects peritoneal penetration by demonstrating intraperitoneal fluid or air. CT scan was unreliable in detection of bowel injury and does not demonstrate diaphragmatic injuries.
