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

purposeThe quadratus lumborum block (QLB) is a relatively new regional analgesic technique that could provide analgesia to the abdominal wall and reduce postoperative opioid consumption. We investigated the opioid-sparing effect of a unilateral lateral QLB in laparoscopic nephrectomy. PATIENTS AND

methodsA total of 60 patients undergoing laparoscopic nephrectomy were included in the study. Patients were randomized into two groups as QLB and control group. QLB group received QLB with 25mL 0.25% ropivacaine, and the control group received 25mL 0.9% saline at anterolateral border of quadratus lumborum muscle preoperatively. Opioid consumption and the pain intensity at rest and on movement were measured at 2nd, 6th, 24th, and 48th hour postoperatively. We also assessed the time to first flatus to measure the extent of paralytic ileus and the quality of recovery-15 (QoR-15) questionnaire.

resultsPostoperative opioid consumption was significantly lower in the QLB group than in the control group at 6, 24, and 48h after surgery (

conclusionPreoperative unilateral QLB successfully decreased postoperative pain and opioid consumption after laparoscopic nephrectomy and could be an option for analgesia after laparoscopic nephrectomy.
