Efficacy and safety of intranasal ketamine compared with intranasal dexmedetomidine as a premedication before general anesthesia in pediatric patients: a systematic review and meta-analysis of randomized controlled trials.
Synthesis in Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
purposeTo compare the efficacy and safety of intranasal ketamine with intranasal dexmedetomidine as a premedication in pediatric patients undergoing general anesthesia for elective surgery or other procedures. SOURCE: We conducted a systematic literature search in PubMed, PubMed Central, Scopus, LILACS, Google Scholar, the Cochrane Database of Systematic Reviews, and trial registries for randomized controlled trials (RCTs) comparing intranasal ketamine with intranasal dexmedetomidine as preanesthetic medication in elective surgery or other procedures in pediatric patients. We used Review Manager software version 5.4.1 for statistical analysis and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We assessed the methodological quality of the included studies with the RoB 2 risk of bias tool. All outcomes were pooled using the Mantle-Haenszel method and a random-effects model. The quality of evidence was assessed using the GRADE approach. PRINCIPAL
findingsOut of 2,445 full texts assessed, we included ten RCTs in the analysis. The efficacy outcomes did not fulfill the comparability criteria between intranasal ketamine and intranasal dexmedetomidine for sedation at parental separation (risk ratio [RR], 0.90; 95% confidence interval [CI], 0.79 to 1.04; I
conclusionThe low to very low-quality evidence in this systematic review and meta-analysis of RCTs neither confirmed nor refuted comparable premedication efficacy of intranasal ketamine and dexmedetomidine in terms of parental separation, mask acceptance, and iv cannulation in a pediatric population. Clinical decision-making is likely to be influenced by differences in gastrointestinal and cardiovascular safety profiles. STUDY REGISTRATION: PROSPERO (CRD42021262516); registered 22 July 2021.
