ABSTRACT
The objective of this study was to use trauma registry data to describe the number and characteristics of patients 21 years or younger receiving thromboprophylaxis with low-molecular-weight heparin at 2 pediatric and 2 adult level 1 trauma centers. Among 706 patients, the average age was 18.5 years, and 94.6% were hospitalized at adult centers. The most common injuries were lower extremity fractures (35.6%) and head injuries (20.4%). Major bleeding was reported in 3 patients (0.4%), and thrombotic events were reported in 15 patients (2.1%). Despite a lack of scientific evidence, low-molecular-weight heparin prophylaxis is being used in young trauma patients (primarily those 14 years or older). Prospective multicenter studies are needed to accurately describe the risks and benefits of low-molecular-weight heparin prophylaxis in young trauma patients, thereby identifying those who truly benefit from this intervention.

BACKGROUND: Various decision algorithms have been developed for use in the prehospital setting to analyze those trauma patients who do not require spinal immobilization. The feasibility of applying these algorithms in the air medical transport environment has not been studied. METHODS: All adult patients (>/=age 16) transported to three Level I trauma centers were eligible for the study. Medical crews completed a data collection sheet during transport which was later used to analyze whether the transported patient would be eligible for spinal clearance based on the absence of all of the following clinical findings: (1) abnormal level of consciousness; (2) evidence of intoxication; (3) distracting painful injury; (4) spinal tenderness or pain; or (5) abnormal neurologic examination. The outcomes were (1) the proportion of transported patients potentially eligible for spinal clearance and (2) the ability of the algorithm to predict spinal injury. RESULTS: Three hundred twenty-nine patients were enrolled in the study. Forty-nine (15%) had spinal injuries with 12 (24%) considered unstable. Only 40 patients met criteria for deferring spinal immobilization; 4 of these patients had spinal fractures. The algorithm had a sensitivity of 90% and a specificity of 16%. CONCLUSION: Clearance of spinal immobilization using prehospital clinical algorithms during air medical transport did not appear to be useful. These criteria were not found to be sensitive, specific, or predictive of spinal injury in this population of blunt trauma patients. Prehospital spinal immobilization clearance algorithms using existing criteria should not be adopted for patients transported by helicopter.
