哪种戒断会致命：酒精、Benzos 以及那些只会让人痛苦的戒断

🧠 为什么重要

酒精（ALCOHOL）戒断在最后一次饮酒后6至12小时开始：震颤、焦虑、出汗、心动过速、高血压、失眠。幻觉可在12至48小时出现，戒断性癫痫发作（SEIZURES）可在约6至48小时的任何时间发生，震颤谵妄（DELIRIUM TREMENS）可在约48至96小时（2至4天）出现，伴有严重意识混乱、激越、发热和自主神经不稳定；DTs 可致命。使用 BENZODIAZEPINES 如 lorazepam 或 chlordiazepoxide 进行治疗，通常以 CIWA 评分为指导，在给予葡萄糖之前或同时给予 THIAMINE 以预防 Wernicke 脑病，并提供安静、光线充足的房间并采取癫痫发作预防措施。BENZODIAZEPINE 戒断也很危险，会出现癫痫发作；要逐渐减量，切勿突然停药。OPIOID 戒断非常痛苦，但很少危及生命：打哈欠、流鼻涕、出汗、瞳孔扩大、竖毛、痉挛、腹泻和呕吐；使用 methadone 或 buprenorphine 以及对症护理如 clonidine 进行治疗。相比之下，阿片类药物过量（OVERDOSE）是呼吸急症：针尖样瞳孔、呼吸抑制和镇静，可用 NALOXONE 逆转，由于其作用消退比许多阿片类药物更快，可能需要重复给药。STIMULANT 戒断会带来崩溃感，伴有疲劳、抑郁和食欲增加；要监测自杀想法。

ALCOHOL withdrawal begins 6 to 12 hours after the last drink: tremor, anxiety, sweating, tachycardia, hypertension, insomnia. Hallucinations can appear at 12 to 48 hours, withdrawal SEIZURES anywhere from about 6 to 48 hours, and DELIRIUM TREMENS at about 48 to 96 hours (2 to 4 days), with severe confusion, agitation, fever and autonomic instability; DTs can be fatal. Treat with BENZODIAZEPINES such as lorazepam or chlordiazepoxide, usually guided by a CIWA score, give THIAMINE before or with glucose to prevent Wernicke's encephalopathy, and provide a quiet, well-lit room with seizure precautions. BENZODIAZEPINE withdrawal is also dangerous, with seizures; taper, never stop abruptly. OPIOID withdrawal is miserable but rarely life-threatening: yawning, rhinorrhea, sweating, dilated pupils, piloerection, cramps, diarrhea and vomiting; treat with methadone or buprenorphine and symptomatic care such as clonidine. Opioid OVERDOSE, by contrast, is a respiratory emergency: pinpoint pupils, respiratory depression and sedation, reversed with NALOXONE, which may need repeating because it wears off faster than many opioids. STIMULANT withdrawal brings a crash with fatigue, depression and increased appetite; monitor for suicidal thoughts.

🏥 真实场景

⏰ 这位踝关节骨折患者在第一天接受了 CIWA 评估、按计划给予 lorazepam 和 thiamine，并住进安静的房间。第三天过去了，没有出现癫痫发作或 DTs。这位护士在入院时询问“你最后一次饮酒是什么时候”，并相信了“今天早上”这个回答，从而预防了急症，而不是事后处理急症。

⏰ The fractured-ankle client gets a CIWA assessment, scheduled lorazepam, thiamine and a quiet room on day one. Day three passes without a seizure or DTs. The nurse who asked 'When was your last drink?' on admission, and believed the answer of 'this morning', prevented the emergency instead of managing it.

📌 要点总结

• 酒精戒断：6至12 h开始，癫痫发作6至48 h，DTs 48至96 hAlcohol withdrawal: 6 to 12 h onset, seizures 6 to 48 h, DTs 48 to 96 h
• 酒精和 benzo 戒断使用 Benzodiazepines；在给予葡萄糖之前或同时给予 thiamine，但切勿延误低血糖时的葡萄糖给药Benzodiazepines for alcohol and benzo withdrawal; give thiamine before or with glucose, but never delay glucose for hypoglycemia
• Naloxone 用于阿片类药物过量；可能需要重复给药Naloxone for opioid overdose; it may need repeat doses
