Controversy persists over the safety of conducted electrical weapons (CEWs), which are increasingly used by law enforcement agencies around the world. The purpose of this study was to examine injury patterns and physiologic conditions after CEW use under real life conditions.
A retrospective, cohort design was used, examining all CEW uses by one police department during a 6-year period. Data were collected from use-of-force forms and medical records and included conditions surrounding the use of force, medical histories, and data from emergency department evaluations and hospital admissions.
Of 1,101 individuals subjected to (Taser M26 and X26) CEW use during the study period, 92.6% were male, the average body mass index was 26.2, and the age range was 9 to 73 years. Of the 886 (80.5%) with medical records, 46.8% had a psychiatric history and 72.9% had a substance abuse history. Emergency department (ED) evaluations occurred for 295 (26.8%) incidents. Of chief complaints, 41.7% were trauma related, 26.8% were for altered mental status, and 21.7% were for psychiatric evaluation. On presentation, 17.6% had a pulse >120, 1.7% were febrile, and 30.9% were altered; 1.4% met criteria associated with "excited delirium." When laboratory workup occurred, 70.6% had positive urine toxicology and 44.8% had positive alcohol levels. Troponin I was positive for one patient. Other laboratory abnormalities were rare, although extensive evaluations were infrequently done. Admission occurred in 24.4% of ED presentations (6.5% of all subjects); of discharge diagnoses for these patients, 59.7% were psychiatric, 22.2% were for unrelated trauma, 11.1% were for restraint-related trauma, and 6.9% were for unrelated medical diagnoses. No patients died.
Significant injuries related to 6 years of law enforcement CEW use in one city were rare. A large percentage of those subjected to CEW use had diagnoses of substance abuse and/or psychiatric conditions. Most admissions after CEW use were unrelated to law enforcement restraint.
导电电子武器（CEW）的安全性一直存在争议，而世界各地的执法机构对其使用却日益增多。本研究的目的是在现实生活条件下，检查使用CEW后的损伤模式和生理状况。
采用回顾性队列设计，研究一个警察部门在6年期间内所有CEW的使用情况。数据收集自武力使用表格和医疗记录，包括武力使用的相关情况、病史以及急诊科评估和住院治疗的数据。
在研究期间接受（泰瑟M26和X26）CEW电击的1101人中，92.6%为男性，平均体重指数为26.2，年龄范围为9至73岁。在有医疗记录的886人（80.5%）中，46.8%有精神病史，72.9%有药物滥用史。295起（26.8%）事件进行了急诊科评估。在主要症状中，41.7%与创伤有关，26.8%是精神状态改变，21.7%是进行精神科评估。就诊时，17.6%的人脉搏>120，1.7%发热，30.9%精神状态改变；1.4%符合与“激动性谵妄”相关的标准。进行实验室检查时，70.6%的人尿液毒理学呈阳性，44.8%的人酒精检测呈阳性。一名患者肌钙蛋白I呈阳性。其他实验室异常情况很少见，尽管广泛的评估并不常见。24.4%的急诊科就诊患者（占所有受试者的6.5%）住院；这些患者的出院诊断中，59.7%为精神科疾病，22.2%为非相关创伤，11.1%为约束相关创伤，6.9%为非相关医疗诊断。无患者死亡。
在一个城市，6年执法使用CEW导致的严重损伤很少见。接受CEW电击的人群中很大一部分患有药物滥用和/或精神疾病。CEW使用后大多数住院情况与执法约束无关。
