Nitrous Oxide Added at the End of Sevoflurane Anesthesia and Recovery

Summary

Addition of nitrous oxide N2O towards the end of prolonged isoflurane anesthesia hastens patients recovery. The hypothesis is that the addition of N2O at the end of prolonged sevoflurane anaesthesia also hastens early recovery without increasing the frequencies and intensity of PONV and improves quality of recovery.
