Abstract: Objective To seek a safe and convenient anesthesia method for the surgery of children ankyloglossia,and to explore the effectiveness of the intravenous anesthesia: propofol combined with ketamine.Methods 39 pediatric patients with hypertrophic ankyloglossia were included in this study.After compound anesthetic: propofol with ketamine was given,the plastic surgery was carried out without endotracheal intubation.During the surgery,the respiration,blood pressure,pulse and oxyhemoglobin saturation(SpO2) were monitored.The operation time,intraoperative and postoperative adverse reaction were recorded.Results All cases sustained the anesthesia and the surgery,with good vital signs during surgery.The average operation time was 3 mins,and the average anesthesia time was 20 mins.Low SpO2 appeared in 3 cases during surgery.Postoperative symptoms of nausea,vomiting and laryngospasm with varying degrees,were observed in 12 cases.Conclusions The intravenous anesthesia: propofol combined with ketamine,is a safe and effective method for children ankyloglossia,thus it is worth clinical popularization and application.
