Quadratus Lumborum Block Reduced Postpartum Uterine Pain After Normal Spontaneous Delivery: A Prospective, Randomized, Double-Blind, Controlled Trial.
Article in Health science reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and Aims: Normal spontaneous delivery is often accompanied by various types of pain; postpartum uterine pain can persist for 2 or 3 days after childbirth. The quadratus lumborum block (QLB) is a relatively safe, cost-effective, and efficacious pain management strategy used in various abdominal surgeries. The present study aimed to determine the effectiveness of QLB in relieving postpartum uterine contraction pain in the immediate 48 h postpartum period. Methods: Sixty-six women, who normally and spontaneous delivered between May 2022 and August 2022, were randomly assigned to undergo either QLB with 0.375% ropivacaine or QLB with pure normal saline for postpartum uterine pain relief. Primary outcome was the severity/degree of uterine pain according to the visual analog scale (VAS) score. Pain interference impacting participants' activities of daily living before and 1, 6, 12, 24, 36, and 48 h after intervention was a secondary outcome. Results: Those in the ropivacaine group required significantly fewer rescue analgesics and exhibited substantially lower mean VAS pain scores at rest and during activity, and a lower level of pain interference when compared with those in the normal saline group ( Conclusion: QLB was a valuable option for managing postpartum uterine pain after normal spontaneous delivery. It offered the benefits of stable hemodynamics, cost-effectiveness, simplicity, and less pain interference with the activities of daily living, and minimal discomfort during the treatment process, with very few negative side effects.
