Prior to the COVID-19 pandemic, the incidence of self-harm was already on the rise. Hanging/suffocation accounted for 50% of the increase in suicide attempts and remains the second leading cause of death from self-harm in the United States. Studies on the management of near-hanging patients are lacking, and most published literature is retrospective. Following airway and circulation assessment, clinical examination and imaging, namely CT angiography, remain the standard for identifying the injuries associated with near hanging: cervical spine fracture, blunt cerebrovascular injury, laryngeal injury, and injury to the trachea and oropharynx. These injuries, however, are uncommon, and each occur in < 5% of patients in most series. In a large series of critically ill near-hanging patients, > 50% survived to hospital discharge; however, cardiac arrest predicted a poor outcome. The management of asphyxia-related arrest remains controversial. Targeted temperature management has only been studied in a single large multicenter trial, which was retrospective. Given the significant selection bias of targeted temperature management in the treatment of the most ill patients, no firm recommendations can be made. Finally, for survivors, the underlying mental health issues must be addressed to avoid recurrent suicide attempts. Thirty percent of patients in a large near-hanging series were admitted for their second suicide attempt.
在 COVID-19 大流行之前,自残的发生率已经在上升。上吊/窒息占自杀未遂人数增加的 50%,仍然是美国自残导致死亡的第二大原因。对近吊患者管理的研究不足,大多数已发表的文献都是回顾性的。在评估气道和循环后,临床检查和影像学,即 CT 血管造影,仍然是识别与近吊相关损伤的标准:颈椎骨折、钝性脑血管损伤、喉损伤以及气管和口咽损伤。然而,这些损伤并不常见,在大多数系列中,每个损伤的发生率都<5%。在一项对重症近吊患者的大型系列研究中,超过 50%的患者存活至出院;然而,心脏骤停预示着预后不良。与窒息相关的心脏骤停的处理仍然存在争议。目标温度管理仅在一项大型多中心回顾性试验中进行了研究。鉴于目标温度管理在治疗最严重患者方面存在明显的选择偏倚,因此无法做出明确的建议。最后,对于幸存者,必须解决潜在的心理健康问题,以避免再次自杀。在一项大型近吊系列研究中,有 30%的患者因第二次自杀企图而入院。
