Intravenous Anesthesia Provides Optimal Surgical Conditions During Microscopic and Endoscopic Sinus Surgery

Abstract

Intravenous anesthesia using propofol-remifentanil provides better surgical conditions compared with a traditional balanced anesthesia technique using isoflurane-alfentanil. It is hypothesized that lower cardiac output caused by decreased heart rate during deep general anesthesia is responsible for this result.
