目的 观察低浓度布比卡因联合全身麻醉在腹腔镜下直肠癌根治术中的应用及对患者体征及苏醒质量的影响。方法 选择2020年1月—2021年6月在信阳一五四医院实施腹腔镜镜下直肠癌根治术治疗的126例直肠癌患者为研究对象,通过抽签法对患者进行分组,将其中63例列为全麻组,术中单纯实施全身麻醉,其余63例列为联合组,术中采用低浓度布比卡因联合全身麻醉,比较两组患者体征变化情况,苏醒质量,麻醉相关不良反应,并开展为期1.5年的随访,评估两组患者远期生存质量。结果 联合组术中、术后的心率、平均动脉压均低于全麻组（P<0.05）;术后,联合组的Steward麻醉苏醒评分略低于全麻组、麻醉恢复室停留时间略高于全麻组（P>0.05）;但联合组的视觉模拟疼痛评分、镇静评分均低于全麻组（P<0.05）;联合组的麻醉相关不良反应发生率略高于全麻组（P>0.05）;随访期间,联合组的肠癌患者生存质量测定量表各维度评分均高于全麻组（P<0.05）。结论 低浓度布比卡因联合全身麻醉的麻醉效果更加平稳、安全性高。

Objective To observe the application of low concentration bupivacaine combined with general anesthesia in laparoscopic radical resection of rectal cancer and its effect on the physical signs and recovery quality of patients. Methods In this study,126 rectal cancer patients who underwent laparoscopic radical resection of rectal cancer in Xinyang 154th Hospital from January 2020 to June 2021 were selected as the research subjects．The patients were divided into groups by drawing lots．Among them,63 patients were included in general anesthesia group,and the rest 63 patients were included in combined group．Low-concentration bupivacaine combined with general anesthesia was used in combined group during the operation．The changes of physical signs and the quality of recovery were compared between the two groups．Anesthesia related adverse events,and the long-term quality of life of the two groups of patients was evaluated through one-year and a half follow-up. Results The heart rate and mean arterial pressure during and after surgery in the combined group were lower than those in the general anesthesia group（P<0.05）．After surgery,the Steward anesthesia recovery score of the combined group was slightly lower than that of the general anesthesia group,and the PACU stay time was slightly higher than that of the general anesthesia group（P>0.05）．However,the VAS score and Richmond Agitation-Se dation Scale score of the combined group were lower than those of the general anesthesia group（P<0.05）．The incidence of anesthesia related adverse reactions in the combination group was slightly higher than that in the general anesthesia group（P>0.05）．During the follow-up period,the FACT-C scores of all dimensions in the combination group were higher than those in the general anesthesia group（P<0.05）. Conclusions The anesthesia effect of low concentration bupivacaine combined with general anesthesia is significant and safe．

目的 探讨蛛网膜下腔注射布比卡因与舒芬太尼预防剖宫产术中寒战效果的影响。方法 选取我院拟行剖宫产手术的产妇158例随机分为对照组(n=79)和观察组(n=79),两组均行蛛网膜下腔注射麻醉下的剖宫产术,对照组给予麻药为质量浓度为5 g/L的布比卡因,观察组为质量浓度为5 g/L的布比卡因+小剂量舒芬太尼,观察两组术中预防寒战效果。结果 观察组寒战发生率(16.64%)低于对照组(39.25%)(P<0.05);MAP、HR组内各时间点间有差异(P<0.05),组间同时间点比较无差异(P>0.05);观察组牵拉痛程度轻于对照组(P>0.05);两组新生儿1min Apgar评分和5min Apgar评分无差异(P>0.05);观察组产妇不良反应发生率为6.33%,与对照组的12.66%比较,无差异(P>0.05)。结论 剖宫产术进行蛛网膜下腔注射布比卡因和舒芬太尼,对预防产妇术中寒战的效果的具有积极影响。

目的 对比观察罗哌卡因及布比卡因应用于患有妊娠期高血压的产妇行剖宫产时腰麻联合硬膜外麻醉的临床效果。方法 将103例择期行剖宫产手术的妊娠期高血压患者随机分为罗哌卡因组51例及布比卡因组52例分别采用对应药物进行麻醉,研究两组阻滞效果、心血管系统变化情况及不良反应发生情况。结果 两组间麻醉镇痛效果及优良率比较,差异没有统计学意义(P>0.05)。罗哌卡因组感觉及运动阻滞起效时间较布比卡因组长,运动阻滞恢复时间较布比卡因组短(P<0.05)。心血管系统变化情况比较,麻醉5min、10min时两组收缩压及平均动脉压均降低,但布比卡因组波动更大,两组间比较差异显著(P<0.05),心率及血氧饱和度比较无差异(P>0.05)。罗哌卡因组不良反应出现时间较布比卡因组晚,同时其不良反应发生率较布比卡因组低(χ²=4.1599,P<0.05)。结论 罗哌卡因及布比卡因在阻滞时间上略有差异,麻醉镇痛效果相当,但鉴于妊高症产妇本身心血管系统存在基础问题,运用罗哌卡因对心血管系统的影响较小,安全性更高,更值得推荐使用。
