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

backgroundTransversus abdominis plane blocks are an established method of postoperative analgesia for abdominopelvic surgeries. Liposomal bupivacaine is an extended-release formulation of bupivacaine providing up to 72 h of analgesia. This study aims to determine if transversus abdominis plane blocks performed with liposomal bupivacaine are associated with reduced opioid consumption and level of pain intensity compared to conventional bupivacaine in patients undergoing lower abdominal surgery.

methodsThis retrospective cohort study was conducted at a single institution between December 2020 and December 2021. After institutional review board approval, we identified patients who underwent lower abdominopelvic surgery with transversus abdominis plane blocks done with liposomal or conventional bupivacaine and collected demographic, clinical, and procedural information for analysis. We compared total opioid consumption over 72-h postoperatively in milligram morphine equivalents (MME), frequency of opioid utilization, and average level of pain intensity between groups. These outcomes were also evaluated after adjusting for covariates. Data were presented as mean ± SD, median [IQR] or frequency (%), as appropriate; p < 0.05 was accepted as significant.

resultsA total of 178 patients met inclusion criteria, with 79 patients receiving an admixture of liposomal bupivacaine and conventional bupivacaine and 99 patients receiving conventional bupivacaine. The liposomal bupivacaine group had a median opioid consumption 72-h postoperatively of 47.5 [18-91.8] MME compared to 88 [43.8-160] MME in the conventional bupivacaine group, p = 0.045. Differences in opioid consumption between the groups did not reach statistical significance after adjustment for demographic and clinical characteristics, p = 0.11. There was no significant difference in frequency of opioid use or average pain intensity.

conclusionTransversus abdominis plane blocks using an admixture of liposomal bupivacaine conventional bupivacaine are not associated with decreased opioid consumption or reduced pain up to 72 h following elective abdominopelvic surgery.
