Abstract: Objective: To study the efficacy and safety of sevoflurane inhalation anesthesia and keeping spontaneous breathing in children undergoing the tongue-tie surgery. Methods: 50 children undergoing elective tongue-tie surgery were selected as the research objects. Sevoflurane induction anesthesia with spontaneous breathing for these children were done by the same professional anesthetist. Pulse, blood pressure, oxygen saturation were monitored during the operations, and the operative time, intraoperative adverse rections, drug dosage and recovery time were recorded. Results: Seven cases' SPO₂ were less than 90%, and five of them were remised after jaw-lift, while the other two were remised by pressurized oxygen through a mask. No case was found with tracheal intubation or hypotension. Three cases suffered from laryngeal spasm and relieved without any treatment. Conclusion: Our study supports the view that Sevoflurane induction anesthesia with spontaneous breathing might be a safe and efficient way for children undergoing the tongue-tie surgery.
