AbstractObjective The aim of this study is to compare sedation titrated under target-controlled infusion of propofol and propofol-remifentanil for impacted supernumerary teeth extraction surgery for children. Methods A total of 60 children with anterior maxillary region impacted supernumerary teeth extraction surgery were divided randomly into two groups, namely, propofol group (group P, n=30) and propofol-remifentanil group (group PR, n=30). In group P, a titrated infusion of propofol was started until the modified observer's assessment of alertness/sedation (OAA/S) scale reached level 3 before the actual surgery. In group PR, a remifentanil infusion with a target plasma concentration of 1 ng·mL⁻¹ was started until the operation was finished. A titrated infusion of propofol was also started until the modified OAA/S score reached level 3 before the actual surgery. The Houpt behavior scale was adopted to evaluate the cooperation of each patient in both groups. The heart rate, blood pressure, respiratory rate, oxyhemoglobin saturation, and Narcotrend index, complications, adverse reactions and propofol infusion of all patients were recorded during the operation. Results The Houpt behavior scales in group PR were better than those in group P (P<0.05). The oxyhemoglobin saturation and respiratory rate in group PR were lower than that in group P (P<0.05). The heart rate, blood pressure and NI in two groups were no significant difference (P>0.05). The incidence of respiratory depression and anterograde amnesia in group PR were higher than that in group P (P<0.05). Conclusion Sedation titrated under the target-controlled infusion of propofol and that titrated under propofol-remifentanil for impacted supernumerary teeth extraction surgery for children are safe. The sedation titrated under target-controlled infusion of propofol-remifentanil is better than sedation by propofol when inhaling oxygen.
