Randomized Controlled Trial Comparative Study Clinical Trial
[The dosage of sedative was reduced by patient-controlled sedation during epidural anesthesia].
The dosage of sedatives required for sedation was studied in patients who underwent total abdominal histerectomy under epidural anesthesia using patient-controlled sedation (PCS) and in those with anesthesiologist-controlled sedation (ACS). Patients in experimental groups received 1.0 or 1.5 mg bolus dose of midazolam by their request until desirable sedation was obtained using a computer-controlled device. ⋯ The level of sedation showed wider variation in PCS groups than in ACS groups. The results suggest that PCS is a technique which allows reduction of sedatives in patients who undergo operation under local anesthesia.
