This study plans to categorize patients who underwent short-duration ENT surgeries with remimazolam TIVA combined with flumazenil antagonism based on whether their intraoperative BIS values were maintained below 60.
This study plans to categorize patients who underwent short-duration ENT surgeries with remimazolam TIVA combined with flumazenil antagonism into two groups based on whether their intraoperative BIS values were maintained below 60. It aims to compare the differences in postoperative recovery quality between the groups, thereby providing evidence-based support for determining the optimal BIS target range during remimazolam TIVA.
