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.

2 · The registry

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

backgroundMultimodal opioid-sparing analgesia is a key component of the enhanced recovery after surgery (ERAS) protocol for postoperative pain management. Transversus abdominis plane (TAP) block has contributed to the implementation of this approach in different kinds of surgical procedures. The aim of this study was to evaluate the efficacy of TAP block and its impact on recovery in colorectal surgery.

methodsA comprehensive literature search of the PubMed, Embase, and Scopus databases was conducted. Studies that compared TAP block to a control group (no TAP block or placebo) after colorectal resections were included. The effects of TAP block in patients undergoing colorectal surgery were assessed, including the technical aspects of the procedure. Two measures were used to evaluate the effectiveness of postoperative pain control: a numeric pain rating score at rest and on coughing or movement at 24 h following surgery and the opioid requirement at 24 h. Clinical aspects of recovery were postoperative ileus, surgical site infection, postoperative nausea and vomiting, and length of hospital stay.

resultsSixteen studies were included in the analysis. Data showed that TAP block is a safe procedure associated with a significant reduction in the pain score at rest [WMD - 0.91 (95% CI - 1.56; - 0.27); p < 0.05] and on coughing or movement [WMD - 0.36 (95% CI - 0.72; - 0.01); p < 0.05] at 24 h after surgery and a significant decrease in morphine consumption in the TAP block group the day after surgery [WMD - 2.07 (95% CI - 2.63; - 1.51); p < 0.001].

conclusionsTAP block appears to provide both an effective analgesia and a significant reduction in opioid use on the first postoperative day after colorectal surgery. Its use does not seem to lead to increased postoperative complications.
