Comparison of Preoperative and Postoperative Intraperitoneal Nebulised Ropivacaine in Laparoscopic Gastric Bypass: A Randomised Clinical Trial.
Trial report in Obesity surgery, 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
backgroundIntraperitoneal administration of local anaesthetics (IPLA) is commonly used in laparoscopic surgery as part of multimodal analgesia.
methodsThis CT included 110 patients. Patients were randomly assigned to receive nebulised ropivacaine either before or after surgery. Pain was assessed using the Visual Analogue Scale (VAS) at multiple postoperative intervals. Secondary outcomes included analgesic consumption, shoulder pain, oral intake tolerance, early mobilisation, and incidence of nausea and vomiting.
resultsNo significant differences were observed in abdominal pain scores or any of the secondary outcomes between groups, except for reduced shoulder pain 3 hours postoperatively in the postoperative nebulisation group.
conclusionUnder a standardised opioid-free anaesthesia protocol, postoperative pain was minimal and substantially lower than expected. Therefore, the timing of intraperitoneal ropivacaine administration does not appear to be relevant.
