Post-cesarean analgesia: transversalis fascia plane block versus wound infiltration in a randomized trial.
Trial report in Revista da Associacao Medica Brasileira (1992), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
objectiveThe aim of this study was to compare ultrasound-guided transversalis fascia plane block with local wound infiltration using equivalent local anesthetic doses within a standardized multimodal analgesia protocol.
methodsThis prospective, single-blind randomized trial was conducted between May and June 2024 at a tertiary care hospital. Women with American Society of Anesthesiologists physical status II-III undergoing cesarean delivery under spinal anesthesia received either bilateral ultrasound-guided transversalis fascia plane block or local wound infiltration with the same total dose and volume of bupivacaine. All patients were managed with standardized multimodal analgesia. Patients with contraindications to the study interventions or inability to use patient-controlled analgesia were excluded. The primary outcome was 24-h opioid consumption. Secondary outcomes included pain scores, rescue analgesia use, opioid-related adverse events, and complications.
resultsForty-two patients (n=21/group) were analyzed. Twenty-four-hour opioid consumption was similar between transversalis fascia plane block and local wound infiltration groups (median 100 [65-152] mg vs. 85 [65-135] mg; p=0.554). Pain scores remained low and comparable throughout 48 h. Rescue analgesia was rarely required, and no postoperative nausea, opioid-related adverse events, or procedure-related complications were observed.
conclusionIn a standardized multimodal analgesia setting after cesarean delivery, transversalis fascia plane block did not reduce opioid consumption or improve postoperative pain scores compared with local wound infiltration.
