目的 观察托烷司琼预处理配合丙泊酚全身麻醉对预防术后恶心呕吐（PONV）的应用价值。方法 采用前瞻性研究,纳入融通集团信阳154医院在2021年6月—2022年12月期间收治的接受腹腔镜手术治疗的122例患者,所有患者均实施含丙泊酚的全身麻醉辅助手术,采用随机数字表法对入组患者进行分组,分别列为预处理组（61例）和常规组（61例）,常规组术后予以常规止吐,预处理组采用托烷司琼预处理,比较两组患者术后6 h、术后12 h、术后24 h及术后48 h等不同时间点的PONV发生率、呕吐症状改善情况,麻醉苏醒后的疼痛、镇静情况,以及术后48 h内的麻醉相关不良反应发生情况。结果 预处理组术后6 h的PONV发生率为3.28%（2/61）,术后12 h的PONV发生率为4.92%（3/61）,术后24 h的PONV发生率为3.28%（2/61）,术后48 h的PONV发生率为0.00%（0/61）,均低于常规组[16.39%（10/61）、18.03%（11/61）、16.39%（10/61）、13.11%（8/61）],差异有统计学意义（P<0.05）。预处理组术后6 h的恶心呕吐干呕症状评估量表（INVR）评分为（20.15±5.41）分,术后12 h的INVR评分为（17.66±4.42）分,术后24 h的INVR评分为（13.29±4.17）分,术后48 h的INVR评分为（10.22±3.35）分,均低于常规组[（23.32±5.13）分、（20.12±4.35）分、（16.33±4.24）分、（12.75±3.06）分],差异有统计学意义（P<0.05）。预处理组苏醒后的视觉模拟疼痛量表（VAS）评分为（4.04±1.06）分,Ramsay镇静评分为（3.11±0.25）分,与常规组[（3.87±0.25）分、（3.06±0.35）分]比较差异无统计学意义（P>0.05）。术后48 h内,预处理组的麻醉相关不良反应发生率为9.84%（6/61）,与常规组8.20%（5/61）比较差异无统计学意义（P>0.05）。结论 托烷司琼预处理辅助含丙泊酚腔镜全身麻醉腹手术可有效降低PONV发生风险并改善患者PONV相关症状,联合应用此药未对麻醉镇静、镇痛效果产生明显影响,且未明显增加术后麻醉相关不良反应发生风险,安全性较高。

Objective To observe the application value of tropisetron preconditioning combined with propofol general anesthesia in the prevention of postoperative nausea and vomiting（PONV）．Methods This is a prospective cohort study．The patients were included from June 2021 to December 2022．The subjects of the study were 122 patients who received laparoscopy．All patients received general anesthesia assisted surgery containing propofol．The enrolled patients were divided into preconditioning group（61 cases）and conventional group（61 cases）by random number table．The conventional group was given routine antiemesis after surgery,and the preconditioning group was given tropisetron preconditioning．The incidence of PONV,improvement of vomiting symptoms,pain and sedation after anesthesia awakening,and occurrence of anesthesia related adverse reactions within 48 hours after surgery were compared between two groups of patients at different time points,including 6 hours,12 hours,24 hours,and 48 hours after surgery．Results Under different treatment regimens,the PONV incidence rates in the preconditioning group were 3.28%（2/61）after 6 hours,4.92%（3/61）after 12 hours,3.28%（2/61）after 24 hours,and 0.00%（0/61）after 48 hours．Compared with the conventional group [16.39%（10/61）,18.03%（11/61）,16.39%（10/61）,and 13.11%（8/61）],the incidence rates were lower（P<0.05）．The preconditioning group had an Index of Nausea and Vomiting and Retching（INVR）score of（20.15±5.41）points after 6 hours,（17.66±4.42）points after 12 hours,（13.29±4.17）points after 24 hours,and（10.22±3.35）points after 48 hours．Compared with（23.32±5.13）points,（20.12±4.35）points,（16.33±4.24）points,and（12.75±3.06）points）of the preconditioning group ,the INVR score at each time point was lower（P<0.05）．Under different treatment regimens,the VAS score of the preconditioning group after awakening was（4.04±1.06）points,and the Ramsay score was（3.11±0.25）points,which was similar to the conventional group [（3.87±0.25）points,（3.06±0.35）points]（P>0.05）．Within 48 hours after surgery,the incidence of anesthesia related adverse reactions in the preconditioning group was 9.84%（6/61）,which was similar to 8.20%（5/61）in the conventional group（P>0.05）．Conclusions Tropisetron preconditioning assisted laparoscopy under general anesthesia with propofol can effectively reduce the risk of PONV and improve the PONV related symptoms of patients．The combined use of this drug has no significant impact on the sedation and analgesia effects of anesthesia,and does not significantly increase the risk of postoperative anesthesia related adverse reactions,with high safety．

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．
