Brief Summary:
The aim of the study was to compare the effects of remifentanil-dexmedetomidine and remifentanil-midazolam with mini-mental state examination (MMSE) in monitored anesthesia care (MAC) patients undergoing cystoscopy.

Condition or disease Intervention/treatment Phase
Postoperative Cognitive Functions Drug: Remifentanil Drug: Midazolam Not Applicable

Detailed Description:
Forty patients undergoing cystoscopy receiving remifentanil infusion of 0.05 microgram per kg-1 min-1 were randomized into two groups: Either dexmedetomidine 1 microgram per kg -1 (GroupD) or midazolam 0.2 mg kg-1h-1 (GroupM) were administered intravenously for the first 10 minutes. Subsequently anesthesia was maintained by using the bispectral index(BIS) as a continuous infusion of dexmedetomidine 0.2-0.7 microgram per kg-1h-1 or midazolam 0.05-0.15 mgkg-1h-1. Heart rate, mean arterial pressure, MMSE, sedation and the patient's and surgeon's satisfaction were determined.
