肝脏切除手术属于肝脏良恶性疾病治疗的主要方式，目前随着肝脏外科技术和相关学科的不断发展，肝切除术成为大多数肝胆胰中心的常规术式。随着外科手术治疗进入腔镜时代，腹腔镜肝切除术现在逐渐成为肝脏肿瘤外科治疗主要方式。围手术期精准评估、术中控制出血和术后个体化管理是手术成功的关键。其中控制术中出血仍是肝脏外科和麻醉医生更为关注的重要话题，因此有必要寻找一种更有效、安全的方法来减少肝切除术中出血的发生。目前低中心静脉压（LCVP）技术可以有效减少术中出血降低输血需求，为手术操作者提供更清晰的手术视野，已被广泛应用于临床。然而，国内外也有研究表明在肝切除术中应用LCVP技术的相关问题仍存在争议。因此，本文总结了LCVP技术在肝切除术中应用的相关原理、具体实施方式及对患者术后重要脏器的影响等方面，为临床医师在肝切除术中合理应用此项技术提供参考。

Hepatectomy is the main treatment for benign and malignant liver diseases. At present, with persistent development of liver surgery and related disciplines, hepatectomy has become a routine procedure in most hepatobiliary and pancreatic disease centers. When surgery enters the era of laparoscopy, laparoscopic hepatectomy has gradually become the main surgical treatment for liver tumors. Accurate perioperative evaluation, intraoperative bleeding control and postoperative individualized management are the keys to successful operation. Among them, intraoperative bleeding control remain a more important topic for surgeons and anesthesiologists in liver surgery. Consequently, it is necessary to explore a more effective and safer technology to minimize intraoperative bleeding during hepatectomy. Currently, low central venous pressure (LCVP) can effectively minimize intraoperative bleeding, reduce the requirement for blood transfusion, and provide a clearer view of surgical field for surgeons, which has been widely applied in clinical practice. However, studies at home and abroad also show that the application of LCVP in hepatectomy remains controversial. Therefore, in this article, relevant principles, specific implementation patterns and the impact of LCVP on vital organs of patients after hepatectomy were reviewed, aiming to provide reference for clinicians to rationally apply LCVP in hepatectomy.
