Abstract

OBJECTIVE: Adequate maintenance of hypnosis during anesthesia throughout surgery using sevoflurane alone was investigated. In addition, sevoflurane pharmacokinetics during cardiopulmonary bypass were analyzed. DESIGN: This was a pilot pharmacokinetic study. SETTING: Tertiary care university hospital. PARTICIPANTS: The study comprised 10 patients aged between 18 and 75 years who underwent elective mitral valve surgery. INTERVENTIONS: The end-tidal and sevoflurane plasma concentrations were measured throughout cardiac surgery procedures involving cardiopulmonary bypass. The sevoflurane plasma concentration was measured using gas chromatography. In addition, the ratio between sevoflurane alveolar concentration and inspired concentration over time (FA/FI) was analyzed to describe wash-in and wash-out curves. MEASUREMENTS AND MAIN RESULTS: Hypnosis was maintained adequately throughout surgery using sevoflurane alone. The bispectral index was maintained between 40 and 60 during cardiopulmonary bypass. The end-tidal sevoflurane was significantly different before and during cardiopulmonary bypass (1.86%±0.54% v 1.30%±0.58%, respectively; p
