Point-of-care ultrasound may be an alternative to radiographs for diagnosing long bone fractures when medical resources are limited. Safe and timesaving, ultrasound also can be used in the ED as a screening tool for suspected long bone fractures and can detect associated musculoskeletal injuries. Ultrasound can be used in radiation-sensitive patients such as children and pregnant patients.Studies have found that clinicians using ultrasound can detect long bone fractures with an average 90% sensitivity and specificity after an average of 1 to 4 hours total of didactic and practical training. More research is needed to determine standards for ultrasound training, patient morbidity outcomes, cost effectiveness, and insurance benefits.
在医疗资源有限的情况下,床边超声检查可能是诊断长骨骨折的一种替代 X 光的方法。超声检查安全且省时,也可以在急诊科用作疑似长骨骨折的筛查工具,并可以检测相关的肌肉骨骼损伤。超声检查可用于对辐射敏感的患者,如儿童和孕妇。研究发现,经过平均 1 至 4 小时的理论和实践培训,使用超声检查的临床医生可以检测出长骨骨折,平均灵敏度和特异性分别为 90%。还需要更多的研究来确定超声检查培训的标准、患者发病率结果、成本效益和保险效益。
