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

introductionThe analgesic effect and safety of transversus abdominis plane block (TAPB) is still controversial in various abdominal procedures. Quadratus lumborum block (QLB) has been considered to provide a widespread and long-lasting analgesic effect in gynecological surgeries. However, the analgesic effects of these two techniques in patients with extreme obesity undergoing laparoscopic sleeve gastrectomy (LSG) are still unknown.

methodsA total of 225 patients with obesity were randomly assigned to group TAPB (n = 76, 30 ml 0.33% ropivacaine with dexmedetomidine 1 μg kg

resultsComparing with patients in the GA group, VAS scores of incision and viscera were consistently reduced during the initial 6-12 h after LSG in TAPB and QLB groups, and they received less propofol and remifentanil (P < 0.001) as well. In the QLB group, patients had longer duration for the first rescue analgesia, and fewer requirements of the rescue analgesia within 24 h than the GA group (P < 0.05). In addition, there were fewer PCA requirements in QLB group than GA and TAPB groups (P < 0.05).

conclusionsUltrasound-guided transversus abdominis plane block and quadratus lumborum block could provide comparable analgesic effects for a laparoscopic sleeve gastrectomy in obese patients.
