TY - JOUR AB - The most common critical incidents in pediatric anesthesia are perioperative respiratory adverse events (PRAEs). The present meta‑analysis aimed to assess the preventive effect of dexmedetomidine on PRAEs in children. Dexmedetomidine is a highly selective α2‑adrenoceptor agonist that provides sedation, anxiolysis and analgesic effects without causing respiratory depression. Dexmedetomidine can diminish airway and circulatory responses during extubation in children. Original randomized controlled trial data were analyzed to study the putative effect of dexmedetomidine on PRAEs. By searched the Cochrane Library, EMBASE and PubMed, a total of ten randomized controlled trials (1,056 patients) was identified. PRAEs included cough, breath holding, laryngospasm, bronchospasm, desaturation (percutaneous oxygen saturation <95%), body movement and pulmonary rales. Compared with placebo, dexmedetomidine resulted in a significant reduction of incidence of cough, breath holding, laryngospasm and emergence agitation. The incidence of PRAEs was significantly reduced in dexmedetomidine compared with active comparators group. Moreover, dexmedetomidine decreased heart rate and increased post‑anesthesia care unit stay duration by 11.18 min. The present analysis suggested that dexmedetomidine improved the airway function and decreased risks associated with general anesthesia in children. The present data demonstrated that dexmedetomidine may be a good choice to prevent PRAEs in children.
