Abstract

Postoperative pain following hemorrhoid surgery is often intense and may affect recovery. This retrospective descriptive study included 70 patients undergoing hemorrhoid surgery at Vinmec Times City International Hospital in 2025, aiming to describe postoperative pain when pudendal nerve block was incorporated into a multimodal analgesia regimen. All patients received ultrasound-guided pudendal nerve block combined with nerve stimulation immediately after surgery. Visual Analog Scale (VAS) scores at 0, 6, 24, and 48 hours postoperatively were all below 4. Rebound pain requiring rescue analgesia occurred in 32.9% of patients, with a mean onset time of 11.04 ± 6.19 hours after the block. 35.7% had postoperative urinary retention, while 1.4% reported nausea or vomiting. The mean length of hospital stay was 2.14 ± 1.2 days, and patient satisfaction was high (9.23 ± 0.7). These findings indicate generally low postoperative pain levels without a notable increase in complications in patients receiving pudendal nerve block as part of a multimodal analgesia regimen.
