Hepatic resection is a major surgery associated with intraoperative massive fluid shifts, blood loss, haemodynamic instability and risk of development of post-hepatectomy liver failure. Hepatic resection predisposes the patient to coagulopathy as well as venous thrombosis. However, due to the development of deranged coagulation profile post-operatively, there is a dilemma in starting thromboprophylaxis. Our aim in this study was to determine the incidence of coagulopathy in patients undergoing major hepatectomy.
In this retrospective study, we included 86 patients who had undergone major hepatectomy between January 2010 and December 2015 at our centre. Intraoperatively, we noted the number of liver segments resected, details of epidural catheter insertion, estimated blood loss, transfusion requirement and need for mechanical ventilation post-operatively. Trends of international normalised ratio (INR) and platelet values were recorded until post-operative day 5.
Of the 86 patients, 6 (7%) had an abnormal coagulation profile pre-operatively and 39 (45.34%) patients developed a derangement in their coagulation profile on 1 post-operative day (POD). Platelet count was significantly lower and INR values were significantly higher than the pre-operative values on all 5 PODs. Sixty-seven (78%) patients had pre-operative epidural catheter insertion for post-operative pain management. Mechanical thrombophylaxis was used routinely.
The incidence of post-operative coagulopathy in our patients who underwent major liver resection was 45.34%. Epidural catheters could be removed safely without transfusion between POD 5 and 7. There was no incidence of venous thrombosis or thromboembolism.
肝切除术是一项大型手术,与术中大量体液转移、失血、血流动力学不稳定以及肝切除术后肝衰竭的发生风险相关。肝切除术使患者易患凝血病以及静脉血栓形成。然而,由于术后出现凝血指标紊乱,在开始进行血栓预防时存在两难困境。本研究的目的是确定接受大型肝切除术患者中凝血病的发生率。
在这项回顾性研究中,我们纳入了2010年1月至2015年12月期间在我们中心接受大型肝切除术的86例患者。术中,我们记录了切除的肝段数量、硬膜外导管插入的详细情况、估计失血量、输血需求以及术后机械通气的需求。记录国际标准化比值(INR)和血小板值直至术后第5天的变化趋势。
86例患者中,6例(7%)术前凝血指标异常,39例(45.34%)患者在术后第1天(POD)出现凝血指标紊乱。在所有5个术后日,血小板计数均显著低于术前值,INR值均显著高于术前值。67例(78%)患者术前插入硬膜外导管用于术后疼痛管理。常规使用机械性血栓预防措施。
在我们接受大型肝切除术的患者中,术后凝血病的发生率为45.34%。在术后第5天至第7天之间,硬膜外导管可安全拔除且无需输血。未发生静脉血栓形成或血栓栓塞事件。
