Abstract：Objective To investigate the effect of ultrasound-guided transversus abdominis plane block (TAPB) on anesthesia depth and puncture incision block in laparoscopic cholecystectomy.Methods Eighty-two patients with laparoscopic cholecystectomy admitted to Dongguan Fifth People′s Hospital from January 2017 to February 2018 were selected as the research subjects and randomly divided into control group and study group, 41 cases in each group.The control group received laryngeal mask general anesthesia, while the study group received ultrasound-guided TAPB combined with laryngeal mask general anesthesia.The visual analogue scale (VAS) scores, anesthesia recovery, total incidence of complications, blood pressure and heart rate before and after anesthesia were compared between the two groups.Results In the study group, 2 cases dropped out of the study, 1 case was converted to laparotomy, and 1 case was operated for more than 180 minutes.In the control group, 1 case dropped out of the study and was converted to laparotomy.The VAS scores of umbilical cord, inferior xiphoid process and inferior right costal margin in the study group were lower than those in the control group, the differences were significant (P<0.05).The umbilical VAS score in the study group was significantly lower than that in the subxiphoid and right costal margins, the differences were significant(P<0.05).The extubation time, eye opening time and spontaneous breathing time of the study group were significantly shorter than those of the control group, the differences were significant (P<0.05).The total incidence of complications in the study group was 15.38%, which was significantly lower than 37.50% in the control group, the difference was significant (P<0.05).The systolic blood pressure, diastolic blood pressure and heart rate after anesthesia in the study group were significantly lower than those in the control group, the differences were significant (P<0.05).Conclusion During the anesthesia process of laparoscopic cholecystectomy, ultrasound-guided TAPB has a good anesthetic effect and should be widely used in clinic.
