Intubation conditions and neonatal outcomes with rocuronium versus suxamethonium in cesarean sections: A systematic review and meta-analysis.
Synthesis in BMC anesthesiology, 2025. 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
backgroundWhile general anesthesia is necessary for some emergency deliveries, it carries risks such as failed intubation and neonatal complications. This study investigates whether rocuronium and suxamethonium (also known as Succinylcholine) provide equivalent conditions for airway management and neonatal outcomes during cesarean sections. Ensuring the safety and efficacy of these agents is crucial due to the physiological and hemodynamic changes associated with pregnancy and delivery.
methodWe conducted a systematic review and meta-analysis following PRISMA guidelines. We included studies involving pregnant women undergoing cesarean sections that used rocuronium as an intervention and suxamethonium as a comparator, reporting outcomes such as Apgar scores, surgery duration, and time-related metrics. A comprehensive search of databases was performed up to July 2025. Statistical analyses were performed using RevMan Software, assessing heterogeneity and summarizing findings through mean differences and risk ratios.
resultsOur metaanalysis of six studies comprising 1,122 patients showed that succinylcholine significantly reduced the time from induction to umbilical cord clamping compared with rocuronium (mean difference [MD] 19.21 s; 95% CI 5.15 to 33.27; P = 0.007; I² = 0%). There was no significant difference between groups in time from incision to delivery (MD - 12.72 s; 95% CI - 84.84 to 59.41; P = 0.73; I² = 94%) or in total surgery duration (MD - 1.20 min; 95% CI - 3.70 to 1.30; P = 0.34; I² = 63%). Newborns in the succinylcholine group were more likely to achieve favorable 1 min Apgar scores (risk ratio [RR] 1.87; 95% CI 1.31 to 2.67; P = 0.0006; I² = 0%) and 5 min Apgar scores (RR 2.52; 95% CI 1.21 to 5.25; P = 0.01; I² = 30%), whereas 10 min Apgar scores did not differ significantly (RR 2.51; 95% CI 0.66 to 9.64; P = 0.18; I² = 34%). In the subgroup of scheduled cesarean deliveries, only the 1 min Apgar score remained significantly higher with succinylcholine (RR 1.75; 95% CI 1.10 to 2.77; P = 0.02; I² = 0%).
conclusionThis review suggests that suxamethonium offers benefits like shorter induction-to-cord clamping times and better early Apgar scores. The current evidence is still limited and further well-designed randomized controlled trials are needed to explore the relationship between rocuronium levels and neonatal outcomes.
