Quadratus Lumborum Block for Pain Management After Colorectal Surgery: Systematic Review and Meta-Analysis of Analgesic and Opioid-Sparing Effects.
Review in Journal of pain research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objective: Quadratus lumborum block (QLB) is an emerging regional anesthesia technique, and its efficacy in colorectal surgery (CRS) remains unclear. This systematic review and meta-analysis aimed to evaluate the effect of QLB on pain control, opioid consumption, and postoperative nausea and vomiting (PONV) after CRS. Methods: Relevant articles were acquired from PubMed, Cochrane, Embase, Web of Science, and Scopus from inception to October 9, 2024. The effect of QLB on post-colorectal surgery analgesia, opioid consumption, and secondary outcomes, including time to first analgesic request (TFAR), length of hospital stay (LOS), and PONV, was assessed using mean difference (MD) or relative risk (RR) and corresponding 95% confidence interval (CI). Results: Six studies involving 465 patients were included. QLB significantly reduced the active visual analogue scale (VAS-A) scores at 12 h (MD = -1.06; 95% CI = -1.89, -0.22; P = 0.014) and 24 h (MD = -0.81; 95% CI = -1.19, -0.43; P = 0.000) after CRS compared to sham or no block. However, QLB did not significantly decrease VAS-A at 48 h, or resting VAS (VAS-R) at 12 h, 24 h, or 48 h after surgery. Additionally, QLB had no impact on opioid consumption at 24 h and 48 h after surgery, overall postoperative opioid consumption, or opioid consumption in PACU. Likewise, QLB did not prolong TFAR, shorten LOS, or reduce the incidence of PONV. Conclusion: QLB effectively relieves active postoperative pain following CRS. While it does not significantly reduce resting pain, opioid consumption, or complications, it has potential benefits in analgesia and recovery.
