目的:评价前锯肌平面阻滞-腹直肌后鞘阻滞-全身麻醉用于肝癌切除术的优化效果。方法:择期全麻下行肝癌切除术患者100例，年龄30~64岁，体重指数18~30 kg/mn 2，ASA分级Ⅱ或Ⅲ级，肝功能Child-Pugh分级A或B级，采用随机数字表法分为2组(n n＝50)：前锯肌平面阻滞联合腹直肌后鞘阻滞组(S组)和胸椎旁神经阻滞组(T组)。S组采用0.375%罗哌卡因在超声引导下行前锯肌平面阻滞(20 ml)联合腹直肌后鞘阻滞(10 ml)，T组采用0.375%罗哌卡因在超声引导下行Tn 7和Tn 9椎旁神经阻滞(各15 ml)。静脉注射咪达唑仑、丙泊酚、舒芬太尼和顺式阿曲库铵诱导麻醉，静脉输注丙泊酚和瑞芬太尼、间断静脉注射顺式阿曲库铵维持麻醉，术中维持BIS值40~60。术毕采用舒芬太尼和氟比洛芬酯行PCIA，VAS评分>3分时静脉注射羟考酮5 mg补救镇痛。记录神经阻滞起效时间和操作时间；记录术中舒芬太尼、瑞芬太尼用量和切皮后30 min内心血管事件发生情况；记录术后48 h内PCA有效按压次数和补救镇痛情况；分别于术前24 h、术后24和48 h时行40项恢复质量量表(QoR-40)评分；分别于术前24 h、术后24 h和7 d时抽取外周静脉血标本，测定血清IL-17和干扰素γ的浓度。记录术后首次排气时间、首次下床时间及住院时间。记录术后48 h内恶心呕吐、呼吸抑制、皮肤瘙痒、穿刺部位感染和气胸等不良反应发生情况。n 结果:与T组比较，S组神经阻滞操作时间缩短，术中低血压发生率降低(n P0.05)。2组术后未见不良反应发生。n 结论:相对于胸椎旁神经阻滞联合全身麻醉而言，前锯肌平面阻滞-腹直肌后鞘阻滞-全身麻醉用于肝癌切除术，神经阻滞操作时间缩短，术中低血压发生率降低。“,”Objective:To evaluate the optimization strategy of anesthesia for liver cancer resection using serratus anterior plane block-posterior rectus sheath block-general anesthesia.Methods:One hundred patients, aged 30-64 yr, with body mass index of 18-30 kg/mn 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with liver function Child-Pugh grade A or B, scheduled for elective liver cancer resection under general anesthesia, were divided into serratus anterior plane block combined with posterior rectus sheath block group (group S, n n=50) and thoracic paravertebral block group (group T, n n=50) using a random number table method.Ultrasound-guided serratus anterior plane block (20 ml) combined with posterior rectus sheath block (10 ml) was performed using 0.375% ropivacaine in group S. Ultrasound-guided paravertebral block was performed at Tn 7 and Tn 9(15 ml for each site) with 0.375% ropivacaine in group T. Anesthesia was induced with intravenous midazolam, propofol, sufentanil and cisatracurium and maintained with intravenous infusion of propofol and remifentanil and intermittent intravenous boluses of cisatracurium.BIS value was maintained at 40-60 during operation.Patient-controlled intravenous analgesia (PCIA) was performed with sufentanil and flurbiprofen at the end of operation, and oxycodone 5 mg was intravenously injected as rescue analgesic when the VAS score>3.The onset time and operation time of nerve block were recorded.The intraoperative consumption of sufentanil and remifentanil and occurrence of cardiovascular events within 30 min after skin incision were recorded.The effective pressing times of PCA and requirement for rescue analgesia within 48 h after operation were recorded.The recovery quality was measured using the 40-item quality of recovery questionnaire at 24 h before surgery and 24 and 48 h after surgery.Peripheral venous blood samples were collected at 24 h before surgery and 24 h and 7 days after surgery to determine the concentrations of interleukin-17 and interferon-gamma in serum.The postoperative time to first flatus, first ambulation time, and length of hospital stay were recorded.The nausea and vomiting, respiratory depression, skin itching, puncture site infection, pneumothorax and other adverse reactions were recorded within 48 h after operation.n Results:Compared with group T, the operation time of nerve block was significantly shortened, the incidence of intraoperative hypotension was decreased (n P0.05). No postoperative adverse reactions were found in either group.n Conclusions:Compared with thoracic paravertebral nerve block combined with general anesthesia, serratus anterior plane block-posterior rectus sheath block-general anesthesia has shorter operation time and lower incidence of intraoperative hypotension when used for liver cancer resection.
