【摘要】：目的观察B超引导腹横肌平面阻滞应用于老年患者腹腔镜直肠癌根治术后镇痛效果及对机体免疫功能的影响。方法60例需行腹腔镜直肠癌根治术的老年患者,按照入院顺序编号采取数字随机法分为腹横肌平面阻滞组及生理盐水对照组。腹横肌平面阻滞组于全麻诱导后行B超引导腹横肌平面阻滞,静注0.25%盐酸罗哌卡因30 ml;生理盐水对照组静注等容量生理盐水。术后均给予静脉镇痛泵:舒芬太尼1.00μg/kg+昂丹司琼16.00 mg+地佐辛10.00 mg+生理盐水配置成100 ml,设置2 ml/h,自控时间15 min。观察两组麻醉前(T_0)、术后1 h(T_1)、术后12 h(T_2)、术后24 h(T_3)及术后48 h(T_4)的视觉模拟评分(VAS)及血流动力学相关指标;记录术后24 h镇痛泵按压次数及舒芬太尼使用总量;并抽取静脉血采取流式细胞仪测定CD4~+%、CD8~+%水平,应用酶联免疫吸附法测定γ干扰素(IFN-γ)水平;比较两组术后不良反应。结果与生理盐水对照组比较,腹横肌平面阻滞组于T_1和T_2时点平均动脉压(MAP)降低,T_1、T_2及T_3时点心率(HR)降低(均P0.05);腹横肌平面阻滞组组内比较,T_1时点MAP高于T_0时点,T_1和T_2时点HR高于T_0时点(均P0.05)。与生理盐水对照组比较,腹横肌平面阻滞组于T_1、T_2、T_3和T_4时点VAS评分均更低,且术后24 h按压次数及舒芬太尼总量均降低(均P0.05),CD4~+%水平均升高,IFN-γ水平T_2和T_3时点均升高(均P0.05);不良反应发生率降低(P0.05)。结论B超引导腹横肌平面阻滞应用于老年患者腹腔镜直肠癌根治术后镇痛效果较佳,血流动力学平稳,术后疼痛程度更低,对机体免疫能力具有一定保护作用,且不良反应发生率低,临床应用安全。
[Abstract]:Objective to observe the analgesic effect and effect on immune function of abdominal transverse muscle plane block guided by B-ultrasound in elderly patients after laparoscopic radical resection of rectal cancer. Methods Sixty elderly patients undergoing laparoscopic radical resection of rectal cancer were randomly divided into abdominal transverse muscle plane block group and saline control group according to the order of admission. In the abdominal transverse muscle plane block group, B-ultrasound guided abdominal transverse muscle plane block was induced by general anesthesia, and 0.25% ropivacaine hydrochloride 30 ml; saline control group was injected intravenously with the same volume of saline. All patients were given intravenous analgesia pump: sufentanil 1.00 渭 g / kg ondansetron 16.00 mg dizoxacin 10.00 mg saline was assigned to 100 ml, for 2 ml/h, automatic control time 15 min. The visual simulation scores (VAS) and hemodynamic indexes were observed before anesthesia (T 鈮，
