  "abstract": "Background and Aims Open hysterectomy is often associated with significant postoperative pain. Multimodal analgesia strategies, especially opioid-sparing approaches, are therefore recommended. Abdominal wall nerve blocks (AWB), including the transversus abdominis plane (TAP) and quadratus lumborum (QL) blocks, are gaining popularity in this setting. These blocks mainly target somatic innervation, although QL may offer extended analgesia due to potential paravertebral spread.Methods This retrospective study included 40 women who underwent elective open hysterectomy between January 2023 and December 2024 at a tertiary center and received either a TAP or QL block. Data collected included demographics, ASA status, type of block, anesthetic dose, postoperative pain (numeric scale 0–10), need for rescue analgesia, opioid use, and complications within 72 hours.Results Mean age was 53 years; 75% were ASA II. TAP was performed in 55% and QL in 45%, using ropivacaine (0.2–0.75%). Mean of postoperative pain score was 1.28 ± 1.20, higher in TAP (1.5 ± 1.4) than QL (1.0 ± 0.9), without statistical significance (p = 0.193). Rescue analgesia in the recovery unit was required in 82.5% (72% opioids); 12.5% needed opioids in the first 24 h — more frequent in TAP (18.2%) than QL (5.6%). No complications were observed.Conclusions These results support AWBs as safe, effective elements of multimodal analgesia in open hysterectomy. Despite the absence of statistically significant differences, QL blocks were associated with lower pain scores and reduced need for opioids. The absence of short-term complications reinforces their safety profile.",
