The Alfred P. Murrah Federal Building in Oklahoma City was partially destroyed by a terrorist bomb on April 19, 1995. Injuries were sustained by 759 people, 168 of whom died. ⋯ The closer receiving hospitals used emergency department facilities and minor treatment areas. Few survivors were extricated from the bombing site more than 3 hours after the detonation. Mass casualty plans must provide for improved communications, diversion and retriage from facilities nearest the disaster site, and effective coordination of community and hospital resources.

Review Comparative StudyTreatment of the mangled lower extremity after a terrorist blast injury.
Terrorist bombings, with resultant blast injuries, have been increasing in frequency during the past 30 years. Injury to the musculoskeletal system is common in victims who survive such attacks. Substantial injury to the limbs may occur through several different mechanisms, each of which may affect prognosis and alter the treatment algorithm. ⋯ This management protocol may improve the medical facility's ability to manage system resources while treating patients with severe blast injuries. The decision of whether to salvage or proceed with limb amputation is one of the most difficult in orthopaedic trauma. A basic education in the mechanisms of blast damage, a methodical approach to resuscitation, and mangled extremity treatment, likely can improve surgical success.

ReviewTerrorism and blast phenomena: lessons learned from the attack on the USS Cole (DDG67).
Blast phenomena and injuries to the musculoskeletal system have been well documented for the past 50 years. The USS Cole was attacked in Aden Harbor in Yemen on October 12, 2000. Seventeen sailors were killed and 39 were wounded. ⋯ Fractures of the cranium, spine, pelvis, and long bones denoted increasing severity of injury to critical organ systems. Shipboard firefighting was successful in containing fires and there was very little morbidity from inhalational injuries or burns. Blast phenomena that affect ships or buildings that have been specifically built to absorb a blast attack likely will manifest a different mode and pattern of injury than those seen in traditional terrorist blast events.

The world has been marked by a recent series of high-profile terrorist attacks, including the attack of September 11, 2001, in New York City. Similar to natural disasters, these attacks often result in a large number of casualties necessitating triage strategies. ⋯ By their very nature, trauma centers are best equipped to handle mass casualties resulting from natural and manmade disasters. Triage assessment tools and scoring systems have evolved to facilitate this triage process and to potentially reduce the morbidity and mortality associated with these events.

Comparative StudyRisk factors for pulmonary emboli after total hip or knee arthroplasty.
Because it is difficult to predict which patients may sustain a pulmonary embolism after total hip or knee arthroplasty, we assessed multiple thrombophilic and hypofibrinolytic parameters to identify risk factors. Twenty-nine patients who survived a known pulmonary embolism after total knee or total hip arthroplasty were matched by age, gender, race, arthritic diagnosis, procedure, and surgery date with 29 patient-controls who had a total hip or knee arthroplasty but who did not have a symptomatic known pulmonary embolism or deep vein thrombosis. Twenty-one serologic measures and five genes associated with thrombophilia, hypofibrinolysis, or both were assessed without knowledge of group assignment. ⋯ Preoperatively, to identify patients at high risk of pulmonary embolism, plasminogen activator inhibitor activity, dilute Russell's viper venom time, prothrombin time, and cholesterol levels were most predictive. Using at least one abnormality of these four measures as a screening test to detect risk of pulmonary embolism, the test is sensitive (100%), and the predictive value of a negative test is high (100%). After additional prospective study, this may allow identification of patients at low risk (the majority of patients) in whom anticoagulation may not be required and a small group of patients at high risk for pulmonary embolism in whom prophylactic anticoagulation should be provided.
