Time-dependent placental transfer of sevoflurane during cesarean delivery under general anesthesia

Key Points

• This research aims to explore how the length of time to delivery affects fetal exposure to sevoflurane during cesarean sections under general anesthesia.
• Analyzed the induction-to-delivery interval during cesarean deliveries
• Measured fetal sevoflurane blood levels
• Evaluated the relationship between delivery time and fetal exposure
• Longer times to delivery are associated with increased fetal sevoflurane exposure.
• End tidal sevoflurane concentration does not accurately predict fetal blood levels.
