摘　　要：目的观察SaCoVLM喉罩在体位改变(截石位及平卧位)情况下是否会引起胃食管反流。方法选择2021年12月1日至2022年9月30日在上海交通大学附属第一人民医院拟行择期手术治疗的患者共70例,包括泌尿外科行输尿管镜手术和创伤骨科行足踝手术患者各35例,分别作为截石位组和平卧位组。患者全麻使用SaCoVLM喉罩通气,置入食道双探头pH电极,连续动态监测食管内酸碱度,比较截石位和平卧位食道内的pH值及其变化趋势,探讨两种体位下胃食管反流发生的可能性。结果患者固定体位后5、10、15、20、30 min,截石位组气道峰压均明显高于平卧位组,差异有统计学意义(P<0.05)。患者在喉罩置入后10 min和15min,截石位组食管中上段pH值均明显低于平卧位组,差异有统计学意义(10 min:6.045±0.490 vs.6.532±0.366,P=0.031;15 min:5.828±0.487 vs.6.474±0.411,P=0.048)。而在喉罩置入后1、5、20和30 min,两组食管中上段pH值的差异无统计学意义。两组患者食管开口处pH值在喉罩置入后各时间点的差异均无统计学意义。结论SaCoVLM喉罩通气下,截石位手术患者胃食管反流的风险可能高于平卧位手术患者。Objective To observe whether SaCoVLM laryngeal mask can cause gastroesophageal reflux when the body position changes(lithotomy position and supine position).Methods A total of 70 patients were selected for elective surgery in Shanghai General Hospital from Dec 1st,2021 to Sep 30th,2022.There were 35 patients with ureteroscopy in urology and 35 patients with ankle surgery in trauma orthopedics selected as lithotomy position group and supine position group,respectively.Under SaCoVLM laryngeal mask anesthesia,a dual probe pH electrode was placed in the esophagus to continuously monitor the pH value in the esophagus.The pH values and their changing trends in the lithotomy position and supine position of the esophagus were compared under general anesthesia with SaCoVLM laryngeal mask ventilation,and the possibility of gastroesophageal reflux occurring in both positions was explored.Results The peak airway pressure at each time point(5 min,10 min,15 min,20 min and 30 min)after body position was determined in the two groups,and it in lithotomy position group was significantly higher than that in supine position group,and the difference was statistically significant(P<0.05).The middle and upper esophageal pH values of the two groups were compared 10 min after laryngeal mask insertion,and it in lithotomy position group(6.045±0.490)was significantly lower than the supine group(6.532±0.366),and the difference was statistically significant(P<0.05).The middle and upper esophageal pH values of the two groups were compared 10 min and 15 min after laryngeal mask insertion.They in lithotomy position group were significantly lower than those in supine position group,and the differences were statistically significant(10 min:6.045±0.490 vs.6.532±0.366,P=0.031;15 min:5.828±0.487 vs.6.474±0.411,P=0.048).There was no significant difference in the pH of the middle and upper esophagus between the two groups at 1,5,20 and 30 minutes of laryngeal mask insertion.There was no significant difference in the pH value of the esophageal ope
