Objective To explore the effects of laryngeal mask ventilation combined with sufentanyl and compound dexmedetomidine anesthesia in patients undergoing laparoscopic hys-terectomy.Methods Eighty patients who proposed laparoscopic hysterectomy in our hospital from July 2019 to December 2022 were divided into control group and observation group using the envelope method,with 40 patients in each group.The control group used trached intubation combined with dexmedetomidine anesthesia,the observation group used laryngeal mask ventila-tion combined with sufentanil compound dexmedetomidine anesthesia,the surgical conditions included recovery time,additional muscle relaxation,heart rate(HR)during surgery,mean arterial pressure were compared,the blood gas status preoperative and postoperative time(30 min,12 h,24 h)were analyzed,and the postoperative complications were compared.Results The wake time of the observation group was significantly shorter than that of control group,less intraoperative additional muscle relaxation than control group,MAP and HR were lower than that of control group,and the difference was statistically significant(twake time=4.583,χ2additionalmusclerelaxation=4.713,tMAP=7.087,tHR=3.066,P<0.05).30 min after surgery,pH in the observation group was higher than that in control group(t30 min=-2.058,P<0.05),there was no difference in pH between the two groups preoperatively,at 12 hours postoperative-ly,and at 24 hours postoperatively(P>0.05);There was no difference in PaO2 levels be-tween the two groups preoperatively,at 30 minutes postoperatively,at 12 hours postoperatively,and at 24 hours postoperatively(P>0.05);There was no difference in PaCO2 levels between the two groups preoperatively,at 30 minutes postoperatively,and at 12 hours postoperatively(P>0.05),the level of PaCO2 in observation group was lower than that in the control group at 24 hours post-operation(t24 h=2.582,P<0.05).The incidence of complications in the ob-servation group was 7.50%,lower than the control group(25.00%),and the difference was significant(χ2overall incidence=4.501,P<0.05).Conclusion The laryngeal mask ventilation combined with sufentanil compound dexmedetomidine anesthesia for patients undergoing laparo-scopic hysterectomy demonstrates good safty,and can reduce the postoperative recovery time,maintain the normal blood gas index,and have high clinical application value.
