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.

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.

Abstract

BACKGROUND AND

objectivesWe aimed to compare the analgesic effects of both posterior (type 2) Quadratus Lumborum Block (QLB) and Transversus Abdominis Plane Block (TAPB) compared to spinal anesthesia alone for postoperative pain management in inguinal hernia repair.

methodsThis study enrolled 63 patients scheduled for open inguinal hernia repair. The eligibility criteria were undergoing elective unilateral inguinal hernia repair surgery, having an American Society of Anesthesiologists (ASA) physical status I, II, or III, and not suffering from any chronic pain condition. Group S patients received spinal anesthetics and no additional analgesic treatments. Group T patients received TAPB, and Group Q patients received QLB as analgesic technique in addition to spinal anesthetics.

resultsThe pain scores at 6 hours (VAS 6) and 24 hours (VAS 24) were significantly different between groups (p < 0.01). Additionally, the sensory and motor block levels were significantly different between groups (p < 0.05). Multiple comparison tests showed that patients in Group Q had significantly higher sensory and motor block levels (p < 0.01 compared with Group S; p < 0.05 compared with Group T). Opioid consumption was significantly different between Groups Q and S (p < 0.01) after surgery.

conclusionsOur findings show that both blocks are similarly effective for the management of postoperative pain compared to spinal anesthesia alone for inguinal hernia repair. We found that QLB resulted in a significant cranial spread compared to TAPB. Opioid consumption in QLB was significantly lower than that in controls but similar to that in TAPB.
