Sugammadex on Remifentanil Ce for Preventing Emergence Cough in Female

Department of Anesthesiology and Pain Medicine, Ajou University School of Medicine

The purpose of this study is to investigate the optimal Ce of remifentanil for preventing emergence cough following extubation during general anesthesia in female who are reversed with sugammadex or neostigmine.

Remifentanil is a potent ultrashort-acting opioid, with rapid onset and offset of drug effect. It allows rapid anesthetic emergence even after a prolonged infusion, and decreases the at-risk time during extubation. In addition, cough suppression of remifentanil enables smooth extubation with reduced complications. However, the infusion of remifentanil suppresses the emergence cough effectively in clinical practice, whereas it still delays the awakening from anesthesia, resulting in prolonged emergence time. Reduced Ce of remifentanil during emergence would decrease the adverse events that are associated with remifentanil infusion.
