Optimal End-Tidal (ET) Sevoflurane and Desflurane Concentration for Extubation of Supreme Laryngeal Mask Airway (LMA) in Adults

• Status: Completed
• Trial end date: 2010-07-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine the optimal volatile anaesthetic (sevoflurane and desflurane) to remove a Supreme LMA in adults in which there is minimal airway response.

Null hypothesis: there is no significant difference between the optimal end tidal concentration of sevoflurane and desflurane for Supreme LMA removal.
