Abstract:
Objective:To explore the clinical value of ultrasound-guided obturator nerve block combined with general anesthesia in transurethral resection of bladder tumors(TURBT)for the elderly.Methods:A total of 84 elderly bladder tumor patients were randomly selected from those admitted to our hospital from November 2017 to August 2019, and were divided into the observation group(n=43)and the control group(n=41)according to whether obturator nerve block was performed.Patients in the observation group were given general anesthesia combined with ultrasound-guided obturator nerve block, and those in the control group were given general anesthesia alone.The surgical conditions, postoperative complications, and rates of adverse reactions were compared between the two groups.Results:Patients in the observation group had a significantly shorter duration of operation, shorter indwelling urinary catheter use, fewer days stayed in hospital and less intraoperative blood loss, compared with the control group(all P<0.05). Besides, the incidence of obturator nerve injury in the observation group was also significantly lower than in the control group(4.65% vs.19.51%, χ2=4.420, P=0.036). There were 2 cases of bladder hemorrhage and 1 case of bladder perforation in the control group, but no case of bladder hemorrhage or bladder perforation occurred in the observation group.A total of 2 cases of tachycardia, 2 cases of nausea and vomiting, and 1 case of hypotension were seen in the control group; and 3 cases of tachycardia, 1 case of nausea and vomiting, and 2 cases of hypotension occurred in the observation group.The total incidence of adverse reactions was similar between the two groups(12.16% vs.13.95%, χ2=0.057, P=0.811). Conclusions:The use of ultrasound-guided obturator nerve block combined with general anesthesia in TURBT surgery can effectively enhance the inhibitive effect on obturator nerve reflex, and reduce the risk of obturator nerve injury during surgery.Therefore, it can ensure smooth operation of the surgery and has a very positive effect on promoting successful postoperative rehabilitation.
