Effectiveness of dexmedetomidine as a premedication for pediatric patients undergoing outpatient dental surgery under general anaethesia-systematic review and meta-analysis
Abstract
Pediatric patients undergoing outpatient dental surgery often exhibit instinctive resistance and fear in face of the unknown, which in turn creates obstacles to subsequent treatment. Appropriate sedation can increase compliance, decrease the incidence of adverse events, and lead to improved treatment outcomes. To evaluate the effectiveness of dexmedetomidine as pre-medication in children undergoing tooth extraction with general anesthesia, we searched databases including the Medline, Embase and Cochrane library for eligible trials. Randomized controlled trials of dexmedetomidine for premedication vs. placebo or midazolam in pediatric patients were included, while trials involving children having dental treatment under local anesthesia were excluded. Two review authors independently participated in the inclusion of trials and assessment of bias. Decisions were made based on group discussion. We finally included seven trials in this review, with a total of 496 pediatric patients. Three of the included trials compared dexmedetomidine with placebo. A meta-analysis indicated that dexmedetomidine was effective for preoperative sedation and for preventing emergence delirium; two of these studies reported no incidences of bradycardia and hypoxemia during study observation period. Four trials compared dexmedetomidine with midazolam, meta-analysis of these four trials gave risk ratios (RR) for successful parental separation, satisfactory mask acceptance and emergence delirium rate of…
