In pediatric surgery, the incidence of perioperative respiratory adverse events in children undergoing tonsillectomy is higher than that of general surgery. Studies have shown that intravenous induction can reduce perioperative respiratory adverse events compared with inhalation induction. There are also literatures that show that intravenous anesthesia can significantly reduce cough and hemodynamic reactions during the wake period compared with balanced anesthesia.However, inhalation anesthesia is easier to use and can monitor the depth of anesthesia, so it is used more frequently than intravenous anesthesia.The incidence of respiratory adverse events has not been compared between intraoperative sevoflurane maintenance and extubation with a small amount of propofol versus total sevoflurane maintenance and extubation.The objective of this study was to investigate whether propofol can reduce perioperative adverse respiratory events in children undergoing tonsillectomy.
The main objective of this study was to investigate whether propofol assisted extubation could reduce the incidence of respiratory adverse events in children with tonsil adenoidectomy.
