Ketamine versus ketamine pluses atropine for pediatric sedation: A meta-analysis

Based on the current evidence, the group receiving atropine had reduced hypersalivation and increased rash and tachycardia; no differences were observed in nausea, vomiting, desaturation, agitation and laryngospasm between the two groups. Given that some of the studies were of low quality, additional high-quality randomized controlled trials should be conducted to further verify these findings.
