Recovery time of midazolam continuous infusion for dental implant surgery

In this study, sedation during implant surgery was performed with the continuous administration of midazolam, and the recovery time was measured. A bolus dose of 0.05 mg/kg was administered to 46 patients with an American Society of Anesthesiologists classification of I or II.

The continuous dose was initiated at 0.025 mg/kg/h and was thereafter adjusted to maintain a bispectral index of 70–80. Midazolam was discontinued at the end of the procedure and the awakening time was defined as that when the bispectral index ≥ 90. After transfer to the recovery room, the patient’s state was evaluated using the post anesthetic discharge score, and subsequently evaluated every 20 min.
