Abstract
IntroductionThe combination of different agents used for procedural sedation allows a greater range of desirable effects while minimizing side effects. The ketamine-dexmedetomidine combination (ketadex) and ketamine-propofol combination (ketofol) are successful examples. The purpose of this meta-analysis was to compare the safety and efficacy of ketadex with ketofol used for procedural sedation in pediatric patients. MethodsWe searched Pubmed, Cochrane Controlled Register of Trials, and Embase from inception to June 2022. Studies were independently evaluated for inclusion criteria and exclusion criteria by two reviewers. Outcome measures for safety comparison were the incidence of hypotension, bradycardia, respiratory depression, nausea, vomiting, and agitation; Outcome measure for efficacy comparison was clinicians' satisfaction. In addition, we compared the recovery time of ketadex and ketofol. ResultsNine studies were included in this meta-analysis. Compared with ketofol, ketadex sedation in pediatric patients had lower risk of respiratory depression (RR: 0.51, 95% CI: 0.34–0.76, P = 0.0009). However, ketadex displayed significant effect on recovery time (MD: 8.38 min, 95% CI: 7.55–9.22 min, P < 0.00001). Ketadex had similar incidence of hypotension (RR: 0.95, 95% CI: 0.33–2.67, P = 0.92) and bradycardia (RR: 1.80, 95% CI: 0.64–5.06, P = 0.26) compared to those with ketofol. Clinicians' satisfaction rate of ketadex and ketofol were both high (RR: 0.93, 95% CI: 0.69–1.25, P = 0.62). Also, no significant difference was observed between ketadex and ketofol on the incidence of nausea, vomiting, and agitation. ConclusionsBoth ketadex and ketofol can provide effective sedation and maintain stable hemodynamics. In consideration of good safety profile in respiratory problems, we suggest ketadex is a better option for procedural sedation in pediatric patients.
