Abstract: Objective To retrospectively analyze the effects of sevoflurane inhalation anesthesia in frenuloplasty in young children, and to discuss its characteristics and safety in clinic. Methods 187 patients at the age of 1-4 years who underwent frenuloplasty under sevoflurane inhalation anesthesia in outpatient department from January 2013 to April 2014 were included in this study. The heart rate, blood pressure, breathing rate, electrocardiogram and oxygen saturation were continuously monitored during operations. All the patients were observed in hospital and not allowed to leave until the Aldrete score reached at least 9. All the cases were reviewed and their data were statistically analyzed. Results All the patients finished operations successfully without struggling or crying and the vital signs were stable during operations. The average anesthesia work time was 48±9.3 seconds, the average operation time was 17.2±5.7 minutes, and the average recovery time was 7.4±8.3 minutes. During recovery, 52 (27.81%) patients were agitated and cried, 2 (1.1%) experienced transient fever, but no complication such as nausea or emesis happened in any patients during and after operations. Also, no complications of anesthesia or operations were detected in the follow-up. Conclusion It is safe and efficient to apply sevoflurane inhalation anesthesia to frenuloplasty in young children.
