Effects of Intravenous Anesthesia and Balanced Anesthesia on Flash Visual Evoked Potentials

• Status: Recruiting
• Trial end date: 2022-12-30
• Target enrollment: 0
• Participant gender: All

Summary

Intraoperative flash visual evoked potentials (FVEPs) could monitor visual function during neurosurgery. There are fewer reports comparing the effects of sevoflurane-propofol balanced anesthesia and propofol-based total intravenous anesthesia under comparable bispectral index (BIS) levels on the amplitude and latency of flash visual evoked potentials (FVEPs) for sellar or parasellar tumors resection neurosurgeries.

• Phase: N/A
• Accepts Healthy Volunteers?: No
