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

backgroundCesarean section is one of the most common surgical procedures. Currently, there are many analgesic methods available after cesarean section, but the optimal analgesic method after cesarean section is not clear.

methodsA network meta-analysis of randomized controlled trials was used to search Embase, PubMed, Web of Science, and Cochrane databases. Outcomes included time to first postoperative request for analgesia, postoperative medication-supplemented analgesia, pain scores at four postoperative time points, postoperative complications (nausea and vomiting, itching, and level of sedation), and patient satisfaction.

resultA total of 110 randomized controlled trials involving 8871 pregnant women were finally included. A total of 17 postoperative analgesic techniques for cesarean delivery were included. Compared with the control group, all modalities except wound infiltration prolonged the time to the first request for analgesia. Transversal abdominal block-type and lumbar quadratus block-type analgesia were effective in decreasing the need for opioids in postoperative patients. Wound infiltration and transversalis fascia plane decreased the need for nonopioid medications in postoperative patients. The traditional analgesic modalities of intrathecal morphine (IM) and epidural morphine have the best analgesic effect, and the analgesic effect of the type of transversal abdominal block and the type of lumbar square muscle block in local anesthesia is better than that of other local anesthesia modalities. The lateral transversus abdominis block and posterior and anterior lumbar square muscle block can effectively reduce postoperative complications with the best effect. In terms of patient satisfaction, IM with conventional Petit transverse abdominal block was the best.

conclusionsRegional nerve block is a safe and effective postoperative analgesic modality; QLB III, which is used to use opioids as postoperative supplemental analgesia, is the safest and most effective analgesic modality, and those who are used to use non-opioids as postoperative supplemental analgesia can choose transversalis fascia plane as a postoperative analgesic modality.
