[Sedation during day surgery for oral implantation].

Background: Oral implantation surgery is performed under sedation without monitoring consciousness, but BIS monitor is useful for evaluation of sedation level. Therefore we investigated whether BIS monitor is useful for this surgery.

Methods: Sixty-four patients scheduled for oral implant surgery were analyzed retrospectively. Patients were classified into two groups; BIS monitor was used (Group B) or not (Group A). We investigated the dose of midazolam necessary for intraoperative sedation, and for patient's satisfaction.

Results: The dose of midazolam in Group B was greater than that in Group A. The dose in Group B was higher than that in Group A according to patient's satisfaction.

Conclusions: BIS monitor is useful for oral implant surgery.
