麻醉深度监测仪引导下不同麻醉深度对老年结肠癌腹腔镜术后苏醒质量的影响

Influence of different depths of anesthesia under the guidance of anesthesia depth detector on awakening quality of elderly patients with colon cancer after laparoscopic surgery

目的:探究麻醉深度监测仪引导下不同麻醉深度对老年结肠癌患者术后苏醒质量的影响。方法:选取2017年2月至2020年6月北京市昌平区医院收治的96例行手术切除的结肠癌老年患者,依照随机抽样的方式将其分为麻醉浅度组、中度组和深度组,每组32例。深度组脑电波双谱指数(BIS)在30~39区间内,中度组BIS在40~49区间内,浅度组BIS在50~60区间内。观察麻醉深度监测仪引导下不同麻醉深度下患者Prince-Henry疼痛量表评分;监测术前(S1)、术成(S2)及术后(S3)3个时期患者促肾上腺皮质激素(ACTH)、皮质醇(Cor)及白细胞介素6(IL-6)应激反应相关指标;以及并发症发生率和认知功能的差异。结果:3组结肠癌患者术后Prince-Henry疼痛评分比较显示,不同麻醉深度的组间差异无统计学意义(P>0.05)。ACTH、Cor及IL-6的应激反应指标在不同麻醉深度组中表现出显著的时间依赖性变化。S2点所有组别的应激反应指标显著增高,浅度组ACTH、Cor和IL-6指标分别为(13.73±1.63)nmol/L、(269.24±31.46)nmol/L和(83.67±3.44)ng/L,中度组分别为(18.26±2.52)nmol/L、(242.56±36.75)nmol/L和(109.35±6.44)ng/L,深度组分别为(19.42±2.42)nmol/L、(432.35±31.34)nmol/L和(132.42±2.31)ng/L,与同组S1比较差异均有统计学意义(t_(浅度组)=7.99、12.48、16.48,t_(中度组)=2.19、6.82、3.03,t_(深度组)=14.21、5.11、20.14,P<0.05)。并发症的发生率中浅度组与中度和深度组比较,差异均有统计学意义(x2=6.342、5.238,P<0.05)。3组术后24 h的MMSE评分显示,浅度组、中度组与深度组比较,差异均有统计学意义(t=4.74、3.77,P<0.05)。结论:麻醉深度对术后恢复质量、应激反应和认知功能有重要影响。利用麻醉深度监测仪调节不同麻醉深度,有助于提高老年结肠癌患者术后的苏醒质量,并减少不良反应发生率。

Objective:To explore the influence of different depths of anesthesia under guidance of anesthesia depth detector on the awakening quality of elderly patients with colon cancer after laparoscopic surgery.Methods:A total of 96 elderly patients with colon cancer who underwent surgical resection and admitted to Beijing Changping District Hospital from February 2017 to June 2020 were selected.They were randomly divided into mild anesthesia group,moderate anesthesia group and deep anesthesia group according to the random sampling,with 32 in each group.The bispectral index(BIS)of deep anesthesia group was within 30-39 interval,and the BIS of moderate anesthesia group was within 40-49 interval,and the BIS of mild anesthesia group was within 50-60 interval.The Prince-Henry pain scale scores of patients with different depths of anesthesia under anesthesia depth detector were observed.The stress response-related indicators included adrenocorticotropic hormone(ACTH),cortisol(Cor)and interleukin-6(IL-6)of patients at three different time points:pre operation(S1),intra operation(S2)and post operation(S3)were monitored.Additionally,the differences of the incidences of complications and the cognitive function also were analyzed.Results:The postoperative Prince-Henry pain scores of the three groups of patients with colon cancer showed there were no statistically significant differences among anesthesia groups with different depths(P>0.05).The stress response indicators included ACTH,Cor and IL-6 appeared significant time-dependent changes among anesthesia groups with different depths.The stress response indicators of all groups significantly increased at S2 point,and the ACTH,Cor and IL-6 levels of mild anesthesia group were respectively(13.73±1.63)nmol/L,(269.24±31.46)nmol/L and(83.67±3.44)μg/L,and these of moderate anesthesia group were respectively(18.26±2.52)nmol/L,(242.56±36.75)nmol/L and(109.35±6.44)μg/L,and these of deep anesthesia group were respectively(19.42±2.42)nmol/L,(432.35±31.34)nmol/L and(132.42±2.31)μg/L.There were significant differences in these indicators in same group between S2 point and S1 point(tmild group=7.99,12.48,16.48,tmoderate group=2.19,6.82,3.03,tdeep group=14.21,5.11,20.14,P<0.05),respectively.The differences of the incidence rates of complication between the mild anesthesia group and the moderate anesthesia group,and between the mild anesthesia and the deep anesthesia group were statistically significant(x^(2)=6.342,5.238,P<0.05),respectively.The MMSE scores 24 hours after surgery indicated that the difference of that between mild anesthesia group and deep anesthesia group,and between moderate anesthesia group and deep anesthesia group were significant(t=4.74,3.77,P<0.05),respectively.Conclusion:The depth of anesthesia has a significant influence on postoperative recovery quality,stress response and cognitive function.Using anesthesia depth detector to adjust the different depth of anesthesia can help to improve the awakening quality of elderly patients with colon cancer post-surgery and reduce the incidence of adverse reactions.
