摘要：

Pediatric dental surgeries are associated with the emotions of fear, anxiety, and other behavioral disturbances of children that need to be managed. Sedation using drugs like dexmedetomidine (DEX) and midazolam (MID) is a common pharmacological behavior managing technique. We conducted this meta-analysis to evaluate the efficacy of both these drugs in current literature.A thorough literature search was conducted on PubMed, MEDLINE, Google Scholar, and Cochrane's database for randomized studies that compared sedative efficacy of dexmedetomidine with midazolam in children of 0–15 years of age undergoing dental surgeries. Sedation in children during dental procedure, when used as a premedication, at the time of separation from parents and at the time of mask induction, onset time, duration of anesthesia, and surgery were evaluated. The mean differences (MDs), odds ratio (OR), and their 95% confidence intervals (CIs) were calculated both for continuous and dichotomous outcome data using random-effects model.Seven studies met out inclusion criteria and were analyzed. Results of premedication with DEX was associated with more anxiolysis (OR=0.29, 95% CI: 0.17–0.52, p =0.0001; I 2 =0%) and at the time of separation from parents (OR=0.36, 95% CI: 0.19–0.69, p =0.002; I 2 =52%) in comparison to MID. No significant differences in results were seen at mask induction (OR=0.63, 95% CI: 0.34–1.18, p =0.15; I 2 =47%) and for sedation in children during dental procedures (OR=0.52, 95% CI: 0.07–3.70, p =0.51; I 2 =72%). Also, there were no significant differences in onset time, duration of anesthesia, and surgery between the two agents.DEX proved to be a better premedicant than MID for pediatric patients. No significant difference in efficacy of both sedative agents was observed in children undergoing dental treatment. More clinical trials need to be conducted to see its efficacy in dental surgeries in children of standardized ages and with standard doses.
