PURPOSE
The purpose of this study was to evaluate circumstances surrounding power saw injuries. We hypothesized that power saw injuries are caused by either inexperienced or inappropriate usage of saws.
METHODS
A retrospective review of patients at our level 1 trauma center from January 2011 to April 2022 was conducted. Patients were screened using surgical billing records based on Current Procedural Terminology codes. Codes associated with revascularization; amputation of digits; and repair of tendon, nerve, and open metacarpal and phalanx fractures were queried. Patients who sustained power saw injuries were identified. They were then contacted by phone, and a standardized questionnaire was administered. Verbal consent was included in the standardized script, which was approved by the institutional review board.
RESULTS
One hundred eleven patients were identified who underwent surgical treatment for power saw injuries of the hands. Of them, we were able to contact 44 patients, who consented to and completed the questionnaire. Of all of the contacted patients, 40 (91%) were men, with an average age of 55 years (range, 27-80 years). No patients were intoxicated when the injury occurred. Thirty-two (73%) patients had used the same saw for more than 25 times. Sixteen (36%) patients had not received formal training regarding safe use of their saw, and 7 (16%) had removed a safety mechanism prior to the injury. Thirteen (30%) patients had used the saw on an unstable surface, and 17 (39%) reported not having changed the saw blade regularly.
CONCLUSIONS
Power saw injuries occur for a multitude of reasons. Contrary to our hypothesis, more experience with the use of saws does not necessarily protect one from saw injuries. These findings highlight the need for formal training among new saw users and continuing education for the more experienced to help reduce the incidence of saw injuries that require surgical intervention.
TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.
目的
本研究旨在评估电锯伤的相关情况。我们假设电锯伤是由经验不足或不当使用电锯所致。
方法
对2011年1月至2022年4月期间在我们一级创伤中心就诊的患者进行回顾性研究。根据现行手术操作术语编码，利用手术计费记录对患者进行筛查。查询与血管重建、手指截肢以及肌腱、神经和开放性掌骨及指骨骨折修复相关的编码。确定遭受电锯伤的患者。随后通过电话联系他们，并发放一份标准化问卷。标准化脚本中包含口头同意内容，该脚本已获机构审查委员会批准。
结果
共识别出111例因手部电锯伤接受手术治疗的患者。其中，我们成功联系到44例患者，他们同意并完成了问卷。在所有被联系的患者中，40例（91%）为男性，平均年龄55岁（范围27 - 80岁）。受伤时无患者处于醉酒状态。32例（73%）患者使用同一电锯超过25次。16例（36%）患者未接受过关于电锯安全使用的正规培训，7例（16%）患者在受伤前拆除了安全装置。13例（30%）患者在不稳定的表面使用电锯，17例（39%）报告未定期更换锯片。
结论
电锯伤的发生原因多种多样。与我们的假设相反，更多的电锯使用经验并不一定能使人避免电锯伤。这些发现凸显了对新电锯使用者进行正规培训以及对经验更丰富者进行继续教育的必要性，以帮助降低需要手术干预的电锯伤发生率。
研究类型/证据水平：预后性IV级。
