BACKGROUND
Bedside ultrasound (BUS) can effectively identify fractures in the emergency department (ED).
AIM
To assess the diagnostic accuracy of BUS for fractures in pediatric trauma patients.
SETTING AND DESIGN
Prospective observational study conducted in the ED.
MATERIAL AND METHODS
Pediatric patients with upper and lower limb injuries requiring radiological examination were included. BUS examinations were done by emergency physicians who had undergone a brief training. X-rays were reviewed for the presence of fracture and the results of BUS and radiography were compared.
STATISTICAL ANALYSIS
STATA version 11 was used for statistical analysis of the data.
RESULTS
Forty-one patients were enrolled in the study. The sensitivity of the BUS in detecting fracture was 89% [95% confidence interval (CI): 51% to 99%] and the specificity was 100% (95% CI: 87% to 100%). The positive predictive value of BUS was 100% and negative predictive value was 97%.
CONCLUSION
BUS can be utilized by emergency physicians after brief training to accurately identify long bone fractures in the pediatric age-group.
背景
床旁超声（BUS）能够有效识别急诊科（ED）的骨折情况。
目的
评估床旁超声对小儿创伤患者骨折的诊断准确性。
设置与设计
在急诊科开展的前瞻性观察性研究。
材料与方法
纳入需要进行放射学检查的上下肢受伤的儿科患者。床旁超声检查由经过简短培训的急诊医生进行。对X线片进行骨折情况检查，并将床旁超声和X线摄影的结果进行比较。
统计分析
使用STATA 11版对数据进行统计分析。
结果
41名患者纳入研究。床旁超声检测骨折的敏感性为89%[95%置信区间（CI）：51%至99%]，特异性为100%（95%CI：87%至100%）。床旁超声的阳性预测值为100%，阴性预测值为97%。
结论
经过简短培训后，急诊医生可利用床旁超声准确识别儿童年龄组的长骨骨折。
