Abstract：Objective To observe the effect of selective nerve block guided by ultrasound in perineum during vestibular glandular resection.Methods A total of 84 patients with vestibular great gland cyst admitted to the Department of Obstetrics and Gynecology of Changsha Central Hospital from March 2019 to March 2021 were selected as the research subjects,and they were divided into observation group(42 cases)and control group(42 cases)by random number table method.The observation group received perineal ultrasound-guided selective nerve block,and the control group received spinal anesthesia.Hemodynamic indexes,perioperative visual analog scale(VAS)score,total incidence of postoperative complications and postoperative recovery time were compared between the two groups before and after anesthesia.Results Before anesthesia,there were no significant differences in systolic blood pressure,diastolic blood pressure,heart rate and VAS score between two groups(P>0.05).30 min after anesthesia,systolic blood pressure,diastolic blood pressure and heart rate of patients in both groups were lower than before anesthesia,the differences were statistically significant(P<0.05).60 min after anesthesia,systolic blood pressure,diastolic blood pressure and heart rate in two groups were higher than those before and 30 min after anesthesia,the differences were statistically significant(P<0.05).The systolic blood pressure,diastolic blood pressure and heart rate of the observation group were lower than those of the control group 30 and 60 min after anesthesia,the differences were statistically significant(P<0.05).At 12 h after anesthesia,VAS scores in both groups were lower than those before anesthesia,the differences were statistically significant(P<0.05).24 h after anesthesia,VAS scores of the two groups were higher than those before and 12 h after anesthesia,the differences were statistically significant(P<0.05).The VAS score of the observation group at 12 and 24 h after anesthesia was lower than that of the control group,the differences were statistically significant(P<0.05).The total incidence of complications in the observation group was 16.67%,lower than 45.2% in the control group,and the difference was statistically significant(P<0.05).The postoperative recovery time of observation group was shorter than that of control group,and the difference was statistically significant(P<0.05).Conclusion Patients with perineal ultrasound-guided selective nerve block during vestibular gland resection have relatively stable hemodynamics,accurate effect and better analgesic effect.Meanwhile,it can reduce surgical complications and shorten postoperative recovery time,which is conducive to the recovery of patients,and is worthy of widespread clinical application.
