Patient-controlled sedation during epidural anesthesia / 中华麻醉学杂志

ABSTRACT

Objective: To evaluate the feasibility and advantages or disadvantages of patient-controlled sedation (PCS) compared with doctor-controlled sedation (DCS) during epidural anesthesia. Method: Forty patients were divided at random into two groups with 20 patients in each group. Patients in group I were administered by themselves a mixture of propofol (20mg) and fentanyl (10?g) in increments using a Graseby PCA infuser (lockout period 1 min) to achieve sedation; patients in group Ⅱ received propofol 3.6mg?kg~(-1)?h~(-1) and fentanyl 1.8?g~(-1)?kg~(-1)?h~(-1)contin uously intravenously by the anesthesiologist to achieve intra-operative sedation. Sedation scale, satisfaction and cooperation degrees were measured. Cognition was also evaluated using abbreviated Mini Mental Status Examination. Result: The drug total dose used in DCS group was higher than that in group PCS (P
