Abstract

Our study aimed to assess the analgesic efficacy and the side effects of single shot pudendal nerve block guided by ultrasound at patients with hemorrhoid surgery. 20 patients with hemorrhoid surgery were relieved of postoperative pain by single shot pudendal nerve block guided by ultrasound from January 2021 to April 2021 at Departement of Anesthesia, Critical Care & Pain Management, Hanoi Medical University Hospital. Sensory blockade, VAS points at rest and during movement, patient satisfaction and the side effects were recorded in 24 hours postoperatively. The average time of procedure is 12,1 ± 1,6 (min). The average depth from the skin surface to the pudendal nerve position was 5.1 ± 0.9 (cm). 89,5 % patients were  the blockade of anterior triangle (urogenital triangle), 10,5 % total pelvic floor. 90 % of patients have very satisfied and satisfied levels. Mean VAS scores at rest were below 3 points and during exercise were approximately 4 points during 24 hours postoperative. Our study is showed that single shot pudendal nerve block guided by ultrasound is an efficient for postoperative pain management at patients with hemorrhoid surgery.
