Acute liver failure is a rare syndrome comprising a coagulopathy of liver origin, jaundice and encephalopathy in a patient with no prior history of liver disease. Paracetamol overdose is the leading cause of acute liver failure in the United Kingdom and often presents with extrahepatic organ dysfunction requiring critical care. We present the case of a patient with hyper acute liver failure secondary to paracetamol overdose. Management focused on ensuring the correct diagnosis had been made, administering N-acetyl cysteine, fluid resuscitation and broad spectrum antimicrobials. Early intubation and transfer to a transplant centre were undertaken following development of hepatic encephalopathy. Neuroprotective measures and hypertonic saline were instituted to reduce the risk of intracranial hypertension. High dose haemofiltration was also started to help reduce ammonia levels. Aggressive critical care therapies with specialised input results in good outcomes for patients admitted with paracetamol induced hyper acute liver failure. Liver transplant is reserved for those patients unlikely to survive with medical treatment alone.
急性肝衰竭是一种罕见的综合征,表现为在无既往肝脏疾病史的患者中出现肝脏源性凝血功能障碍、黄疸和肝性脑病。对乙酰氨基酚过量是英国急性肝衰竭的主要原因,且常伴有需要重症监护的肝外器官功能障碍。我们报告一例因对乙酰氨基酚过量导致超急性肝衰竭的患者。治疗重点在于确保做出正确诊断、给予N - 乙酰半胱氨酸、液体复苏和广谱抗菌药物。在出现肝性脑病后,早期进行了气管插管并转至移植中心。采取了神经保护措施和高渗盐水以降低颅内高压的风险。还启动了高剂量血液滤过以帮助降低氨水平。积极的重症监护治疗并辅以专业支持,使得因对乙酰氨基酚诱发超急性肝衰竭入院的患者取得了良好预后。肝移植仅适用于那些仅靠药物治疗不太可能存活的患者。
