ABSTRACT
The anaesthetic management of adenotonsillectomy in children with obstructive sleep apnea syndrome was characteristic due to respiratory and cardiac side effects. A detailed physical examination in the preoperative period should be performed, including children’s respiratory and cardiac systems. If they have an active infection, surgery should be postponed until the end of medical treatment. Preparation for difficult airway management should be done in the preoperative period. In this case, we presented a report of two children who had obstructive sleep apnea syndrome, with airway management performed at the right lateral position to prevent the pharyngeal collapse and rapid sequence intubation performed using a short-acting muscle relaxant.
