The effect of esketamine on postoperative recovery in children after endoscopic adenoidectomy / 复旦学报（医学版）

ABSTRACT

Objective To observe the effect of esketamine on postoperative recovery in children after endoscopic adenoidectomy.Methods Sixty pediatric patients who underwent adenoidectomy with endoscope from Jan 2022 to Jan 2023 in Eye&ENT Hospital,Fudan University were enrolled.The pediatric patients were randomly divided into hydro-morphine group(n=30)and esketamine group(n=30).Anesthesia induction:lidocaine 1.5 mg/kg,propofol 2.5 mg/kg and remifentanil 4 μg/kg were injected intravenously,and then the endotracheal tube was used for airway management.Anesthesia maintenance:remifentanil infusion was at 0.2-0.5 μg·kg-1·min-1 and the end tidal concentration of sevoflurane was at 0.7-1.0 minimum alveolar concentration(MAC).At the end of surgery,either hydromorphone 0.01 mg/kg or esketamine 0.5 mg/kg were administered for postoperative pain control.Time to resume spontaneous breathing was recorded.Other parameters included respiratory rate per minute,duration of stay in the post-anesthesia care unit,hemodynamic profiles.The adverse events including agitation and desaturation were also of note.Results Children in esketamine group resumed spontaneous breathing faster(P=0.048),had faster respiratory rate when recovery of spontaneous breathing(P=0.001)and lower concentration of end tidal CO2(P=0.005).The findings suggested that esketamine did not impair respiratory function.Compared to hydro-morphine group,children in esketamine group had shorter stay in the post-anesthesia care unit with statistical difference(P=0.020).Esketamine had no effect on heart rate and blood pressure,so there were less adverse events.Conclusion Compared with 0.01 mg/kg hydro-morphine,0.5 mg/kg esketamine does not impair respiratory function and it facilitate fast recovery in children undergoing endoscopic adenoidectomy after general anesthesia.
