Study Objectives Traction splinting has been the prehospital treatment of midshaft femur fracture as early as the battlefield of the First World War (1914-1918). This study is the assessment of these injuries and the utilization of a traction splint (TS) in blunt and penetrating trauma, as well as intravenous (IV) analgesia utilization by Emergency Medical Services (EMS) in Miami, Florida (USA).
This is a retrospective study of patients who sustained a midshaft femur fracture in the absence of multiple other severe injuries or severe physiologic derangement, as defined by an injury severity score (ISS) <20 and a triage revised trauma score (T-RTS)≥10, who presented to an urban, Level 1 trauma center between September 2008 and September 2013. The EMS patient care reports were assessed for physical exam findings and treatment modality. Data were analyzed descriptively and statistical differences were assessed using odds ratios and Z-score with significance set at P≤.05.
There were 170 patients studied in the cohort. The most common physical exam finding was a deformity +/- shortening and rotation in 136 patients (80.0%), followed by gunshot wound (GSW) in 22 patients (13.0%), pain or tenderness in four patients (2.4%), and no findings consistent with femur fracture in three patients (1.7%). The population was dichotomized between trauma type: blunt versus penetrating. Of 134 blunt trauma patients, 50 (37.0%) were immobilized in traction, and of the 36 penetrating trauma victims, one (2.7%) was immobilized in traction. Statistically significant differences were found in the application of a TS in blunt trauma when compared to penetrating trauma (OR=20.83; 95% CI, 2.77-156.8; P <.001). Intravenous analgesia was administered to treat pain in only 35 (22.0%) of the patients who had obtainable IV access. Of these patients, victims of blunt trauma were more likely to receive IV analgesia (OR=6.23; 95% CI, 1.42-27.41; P=.0067).
Although signs of femur fracture are recognized in the majority of cases of midshaft femur fracture, only 30% of patients were immobilized using a TS. Statistically significant differences were found in the utilization of a TS and IV analgesia administration in the setting of blunt trauma when compared to penetrating trauma.

研究目的 早在第一次世界大战(1914 - 1918年)的战场上,牵引夹板就已用于院前治疗股骨干骨折。本研究旨在评估这些损伤情况以及牵引夹板(TS)在钝性和穿透性创伤中的应用,同时评估美国佛罗里达州迈阿密市紧急医疗服务(EMS)对静脉(IV)镇痛的使用情况。
这是一项回顾性研究,研究对象为2008年9月至2013年9月期间在一家城市一级创伤中心就诊的、无其他多处严重损伤或严重生理紊乱(根据损伤严重程度评分(ISS)<20和分诊修订创伤评分(T - RTS)≥10定义)的股骨干骨折患者。对EMS患者护理报告进行体格检查结果和治疗方式评估。对数据进行描述性分析,并使用优势比和Z分数评估统计学差异,显著性设定为P≤0.05。
该队列共研究了170例患者。最常见的体格检查发现是136例患者(80.0%)出现畸形伴或不伴缩短及旋转,其次是22例患者(13.0%)有枪伤(GSW),4例患者(2.4%)有疼痛或压痛,3例患者(1.7%)未发现与股骨骨折相符的体征。根据创伤类型将人群分为钝性创伤和穿透性创伤两组。在134例钝性创伤患者中,50例(37.0%)使用牵引固定,在36例穿透性创伤患者中,1例(2.7%)使用牵引固定。与穿透性创伤相比,钝性创伤中TS的应用存在统计学显著差异(优势比=20.83;95%置信区间,2.77 - 156.8;P <0.001)。在有可获得静脉通路的患者中,仅35例(22.0%)接受静脉镇痛以治疗疼痛。在这些患者中,钝性创伤受害者更有可能接受静脉镇痛(优势比=6.23;95%置信区间,1.42 - 27.41;P =0.0067)。
尽管在大多数股骨干骨折病例中都能识别出股骨骨折的体征,但只有30%的患者使用TS固定。与穿透性创伤相比,钝性创伤中TS的使用和静脉镇痛的给药存在统计学显著差异。纳肯森J、贝兹AA、梅佐索JP。紧急医疗服务对牵引夹板使用和静脉镇痛的描述性分析。院前灾难医学。2017;32(6):631 - 635。
