摘要:

目的 观察目标导向液体治疗(goal‑directed fluid therapy, GDFT)对腹腔镜肝切除术中血流动力学及局部脑氧饱和度(regional cerebral oxygen saturation, rSO2)的影响。 方法 40例18~71岁择期全身麻醉下行腹腔镜肝切除术患者,按随机数字表法分为以每搏量变异度(stroke volume variation, SVV)和心指数(cardiac index, CI)为指导的治疗组(S组)、以CVP为指导的治疗组(C组),每组20例。两组患者均采用气管插管全身麻醉,行桡动脉及颈内静脉穿刺,其中S组通过桡动脉连接LiDCOrapidV2系统监测SVV和CI,C组通过压力传感器连接颈内静脉导管监测CVP。记录两组患者一般情况、手术时间、拔管时间、肝门阻断时间;记录两组患者入室(T0)、气腹即刻(T1)、切肝前10 min(T2)、切肝后10 min(T3)、气腹结束即刻(T4)的MAP、心率、血乳酸(lactic acid, Lac)、血糖、rSO2;记录两组患者术中出入量、去甲肾上腺素用量及术后恢复情况(下床时间、排气时间、住院天数、术后恶心呕吐及术后感染发生率)。 结果 T2、T3时,两组患者心率、MAP均低于T0(P<0.05),S组心率低于C组,MAP高于C组(P<0.05)。与T0比较,C组T2、T3时Lac及血糖升高(P<0.05),且T2、T3时C组高于S组(P<0.05)。两组患者各时点rSO2比较,差异无统计学意义(P>0.05)。与C组比较,S组总输液量、晶体液用量、出血量、去甲肾上腺素用量降低(P<0.05),胶体液用量增加(P<0.05)。两组患者尿量差异无统计学意义(P>0.05)。与C组比较,S组下床时间、排气时间、住院天数缩短(P<0.05),术后恶心呕吐、术后感染发生率降低(P<0.05)。其余指标差异无统计学意义(P>0.05) 结论 腹腔镜肝切除术中以SVV和CI为指导的GDFT安全、有效,血流动力学更加平稳,促进胃肠功能恢复;缩短术后住院时间,患者短期转归较好,并能维持脑氧供需平衡。

Abstract:

Objective To observe the effect of goal‑directed fluid therapy (GDFT) on hemodynamics and regional cerebral oxygen saturation (rSO2) during laparoscopic hepatectomy. Methods A total of 40 patients, aged 18 to 71 years, who were scheduled for laparoscopic hepatectomy under general anesthesia were selected. According to the random number table method, they were divided into two groups (n=20): a stroke volume variation (SVV) and cardiac index (CI) directed treatment group (group S) and a central venous pressure (CVP) directed group (group C). Both patients were under general anesthesia with endotracheal intubation and underwent radial artery and internal jugular vein punctures. In group S, SVV and CI were monitored through the LiDCOrapidV2 system connected to the radial artery, while in group C, CVP was monitored through a pressure transducer connected to an internal jugular vein catheter. Their general information, operation time, exbubation time, and obstructive time of the portal vein were recorded. Both groups were compared for mean arterial pressure (MAP), heart rate, the concentration of blood lactic acid (Lac), blood glucose, and rSO2 when entry into the operating room (T0), immediately after pneumoperitoneum (T1), 10 min before hepatectomy (T2), 10 min after pneumoperitoneum (T3), and at the end of pneumoperitoneum (T4). Furthermore, their volumes of intraoperative fluid inflow and outflow, norepinephrine dosage and postoperative recovery (time to out‑of‑bed activity, time to anal exhaust, length of hospitalization stay, and the incidences of nausea, vomiting, and postoperative infection) were also recorded. Results At T2 and T3, the heart rate and MAP of both groups decreased compared with those at T0. Group S showed lower heart rate but higher MAP than group C (P<0.05). Compared with those at T0, the levels of Lac and blood glucose increased at T2 and T3 in group C, and the levels of Lac and blood glucose in group C were higher than those in group S (P<0.05). No statistically significant differences were observed in rSO2 between the two groups at each time‑point (P>0.05). Compared with group C, total volume of fluid, total crystalloid volume, blood loss and norepinephrine doses significantly decreased in group S, but the volume of colloid increased (P<0.05). No statistically significant differences were observed in urine volume between the two groups (P>0.05). Compared with group C, group S showed markedly shortened time to our‑of‑bed activity, time to anal exhaust, and length of hospitalization stay (P<0.05); the incidences of postoperative nausea and vomiting and postoperative infection also decreased (P<0.05). There was no statistical difference in other indexes (P>0.05). Conclusions During laparoscopic hepatectomy, GDFT guided by SVV and CI is safe and effective, with more stable hemodynamics, better gastrointestinal function recovery, shorter postoperative length of hospitalization stay, and better short‑term outcomes. It also can maintain the balance of cerebral oxygen supply and demand.
