Effect Analysis of Bilateral Pudendal Nerve Block Combined with Epidural Anesthesia on Mixed Hemorrhoid Surgery Patients
Objective:To investigate the effect of bilateral pudendal nerve block(PNB)combined with epidural anesthesia(CEB)in patients undergoing mixed hemorrhoid surgery.Methods:A total of 82 patients with mixed hemorrhoid operation treated in Yicheng District People's Hospital of Zaozhuang City in Shandong Province from May 2022 to May 2023 were selected as the study objects,and were randomly divided into a control group and an experimental group according to random number table method,with 41 cases in each group.CEB was used in the control group,and CEB combined with bilateral PNB anesthesia was used in the experimental group.The excellent and good rate of anesthesia,anesthesia block effect,hemodynamics,internal anal pressure,postoperative pain score and adverse events were compared between the two groups.Results:The excellent and good rate of anesthesia in experimental group was 95.12%,which was higher than 80.49%in the control group,the difference was statistically significant(P<0.05).The onset time of sensory nerve and motor nerve block in the experimental group was shorter than that in the control group,and the maintenance time was longer than that in the control group,with statistical significances(P<0.05).At T1,T2 and T3,heart rate and mean arterial pressure in the experimental group were lower than those in the control group,the differences were statistically significant(P<0.05).At 10 min after operation,anal depression in the experimental group was lower than that in the control group,and the pain Visual Analoyne Scale scores in experimental groups were lower than those in control group at 6,12 and 24 h after operation,with statistical significances(P<0.05).There was no significant difference in the occurrence of adverse events between the two groups(P>0.05).Conclusion:The application of bilateral PNB combined with CEB in patients with mixed hemorrhoid surgery has a high effect,which is helpful to shorten the onset time of anesthesia,prolong the duration of anesthesia maintenance,keep the intraoperative hemodynamic indexes relatively stable,reduce the internal anal pressure during surgery,reduce postoperative pain,and is safe and reliable.
