Prophylactic pharmacological interventions against perioperative respiratory adverse events in children undergoing noncardiac surgery: a systematic review and meta-analysis.
Synthesis in Journal of anesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposePerioperative respiratory adverse event (PRAE) is one of the most common complications in pediatric anesthesia. We aimed to evaluate the efficacy of perioperative pharmacological interventions to prevent the development of PRAE in children undergoing noncardiac surgery.
methodsPubMed, Embase, Cochrane Library and ClinicalTrials.gov were searched for randomized controlled trials (RCT) of prophylactic pharmacological interventions for PRAE among surgical children from inception to 5 August 2024. Pairwise meta-analyses were conducted to compare the effects of an intervention with placebo or another intervention on overall PRAE and their subtypes, including laryngospasm, bronchospasm, oxygen desaturation, airway obstruction, coughing and stridor. Risk of bias was assessed using the Cochrane Collaboration tool.
resultsSeven categories of prophylactic interventions were identified. Twenty-nine RCTs with 4452 children were included. Compared with placebo, lidocaine reduced the odds ratio (OR) of overall PRAE ( 0.27 [95% CI] [0.17, 0.42]) and laryngospasm (0.38 [0.22, 0.67]); dexmedetomidine reduced the OR of PRAE (0.31 [0.12, 0.76]), laryngospasm (0.31 [0.10, 0.91]), coughing (0.24 [0.14, 0.41]) and oxygen desaturation (0.54 [0.35, 0.84]); β
conclusionsThe meta-analysis demonstrated prophylactic potential of lidocaine, dexmedetomidine, β
