Addition of Lidocaine to Ropivacaine and Sufentanil for Epidural Labour Analgesia: A Randomised Double-Blind Study on the Incidence of Epidural-Related Maternal Fever.

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
Background: Epidural-related maternal fever (ERMF) is a common complication of labour analgesia. In vitro evidence suggests ropivacaine provokes inflammatory cytokine release, while lidocaine may exert anti-inflammatory effects. We hypothesized that the addition of lidocaine to a ropivacaine-based epidural solution would reduce the incidence of ERMF. Methods: In this randomised, double-blind trial, 400 parturients received epidural analgesia with 0.075% ropivacaine and 0.5 μg/mL sufentanil, with or without 0.5% lidocaine. The primary outcome was the incidence of ERMF (tympanic temperature ≥38.0°C). Results: ERMF incidence was significantly lower in the lidocaine group (14.1%) than in the control group (28.3%), with an absolute risk reduction of 14.2% (95% Conclusion: The addition of lidocaine to ropivacaine for epidural labour analgesia significantly reduced the incidence of ERMF. This finding suggests a simple and promising strategy for preventing this common complication, warranting further investigation into its mechanisms and clinical utility.
