Acetaminophen overdose is common and can result from deliberate/nonstaggered or accidental/staggered ingestion. Patients presenting within 24 h of an acetaminophen overdose can safely be managed on medical wards. Early management of nonstaggered overdose is guided by the plasma acetaminophen concentration, whereas management of accidental/staggered ingestion is guided by ingested dose. Ingested dose and time from ingestion to presentation are important prognostic factors in accidental/staggered ingestion. Acetaminophen-induced acute liver failure (ALF) requires meticulous supportive care in an intensive care unit (ICU), with early identification and transfer of patients who are likely to require liver transplantation to a specialist liver centre. The modified King's College Hospital criteria (incorporating lactate into the traditional criteria) represent the best tool for identifying patients who require transplantation.
对乙酰氨基酚过量服用很常见,可能是故意/一次性或意外/分次摄入所致。对乙酰氨基酚过量服用后24小时内就诊的患者可在普通病房安全治疗。一次性过量服用的早期治疗以血浆对乙酰氨基酚浓度为指导,而意外/分次摄入的治疗则以摄入剂量为指导。摄入剂量以及从摄入到就诊的时间是意外/分次摄入的重要预后因素。对乙酰氨基酚所致急性肝衰竭(ALF)需要在重症监护病房(ICU)进行精心的支持治疗,早期识别并将可能需要肝移植的患者转至专科肝脏中心。改良的国王学院医院标准(将乳酸纳入传统标准)是识别需要移植患者的最佳工具。
