Comparison of Effect-site Concentration of Remifentanil for Preventing Cough Against Endotracheal Tube During Anesthetic Emergence According to Anesthetics (Sevoflurane, Desflurane, and Propofol)

• Status: Completed
• Trial end date: 2011-10-01
• Target enrollment: 0
• Participant gender: Female

Summary

It has been reported that target-controlled infusion of remifentanil can reduce cough against endotracheal tube during emergence from general anesthesia. We hypothesized that effective concentration of remifentanil for preventing cough during anesthetic emergence varies depending on the type of main anesthetic agents which is administered with remifentanil during general anesthesia. The purpose of this study is to evaluate the effective concentrations of remifentanil to prevent coughing during emergence from general anesthesia according to main anesthetic agent (sevoflurane, desflurane, and propofol).
