1 · What the graph read from it

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.

Abstract

backgroundRectus sheath block (RSB) provides reliable anesthesia to the anteromedial abdominal wall and may offer effective pain control following laparoscopic sleeve gastrectomy (LSG). This study aimed to compare the efficacy of RSB versus local infiltration analgesia (LIA), hypothesizing that RSB would provide superior pain relief.

methodsIn this randomized controlled trial, patients with obesity undergoing LSG received either bilateral ultrasound-guided RSB performed by an anesthesiologist or LIA administered by a surgeon, following anesthesia induction. The primary outcome was intraoperative fentanyl consumption. Secondary outcomes included postoperative pain scores [Numeric Rating Scale (NRS), 0-10], cumulative morphine consumption, and recovery metrics over 48 h.

resultsSixty-nine patients were analyzed (RSB: 35; LIA: 34). Intraoperative fentanyl use was lower with RSB (median difference: - 25 mcg; 95% CI: - 50 to 0; p = 0.008). RSB reduced pain scores at rest at 0 h (-2 points; p = 0.001), 1 h (-1 point; p = 0.009), and 12 h (-1 point; p = 0.022), and pain during movement at 0 h (-3 points; p < 0.001), 12 h (-1 point; p = 0.043), and 36 h (-1 point; p = 0.019). Pain scores were otherwise comparable. Fewer RSB patients reported moderate-to-severe pain at 0 h and 1 h (rest: p = 0.006 and 0.019; movement: p < 0.001 and 0.033). Postoperative morphine use and recovery metrics were similar between groups.

conclusionPre-incisional RSB demonstrated an intraoperative opioid-sparing effect and superior early postoperative analgesia compared with LIA, supporting its role as a component of multimodal analgesia for LSG.
