Ultrasound-guided pudendal nerve block for postoperative pain management in procedures for prolapse and hemorrhoids: a randomized, double-blinded trial.
Trial report in International journal of colorectal disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe study aimed to evaluate the efficacy of ultrasound-guided pudendal nerve block (PNB) versus local anesthetic infiltration (LAI) in managing the pain.
methodsThis is a prospective, randomized, double-blinded trial, 78 patients undergoing procedure for prolapse and hemorrhoids (PPH) were randomly allocated to receive either ultrasound-guided PNB or LAI. Primary outcomes were postoperative pain scores using the visual analogue scale at multiple time points within the first 48 h. Secondary outcomes included tramadol consumption, incidence of postoperative nausea and vomiting, and quality of recovery-15 (QoR-15) scores.
resultsThe trial ultimately involved 71 patients. Results showed that the PNB group had significantly lower pain scores at 6, 12, and 18 h postoperatively compared with the LAI group (all P < 0.01), with no significant differences noted at 24 and 48 h. PNB group also had fewer patients requiring supplemental tramadol (5/36) than the LAI group (12/35) (P < 0.05) and experienced a delayed onset of pain (13.83 ± 11.21 h vs. 6.94 ± 2.88 h; P < 0.001). Furthermore, the incidence of anal sphincter spasms was lower in the PNB group (5/36) compared with the LAI group (12/35) (P < 0.04). QoR-15 scores at 24 h postoperatively were significantly higher in the PNB group (119.11 ± 5.87) compared with the LAI group (112.03 ± 7.04) (P < 0.05), indicating a better early recovery experience. Patient satisfaction was higher in the PNB group (28/36 vs. 22/35, P < 0.05).
conclusionUltrasound-guided PNB was more effective than LAI in pain control and recovery quality. It can be considered an effective method for postoperative pain management in patients undergoing PPH surgery.
