Abstract:
Objective To compare the effects of sedation induced with midazolam and propofol on blood pressure(BP), heart rate(HR) and heart rate variability (HRV) during operation on lower extremity preformed under continuous epidural anesthesia in patients with the type Ⅱ diabetes. Methods Forty patients with type Ⅱ diabetes scheduled for lower limb surgery were randomized to receive either midazolam (group M n - 20) for propofol (group P n = 20) for sedation during operation, all patients were classified as ASA physical status Ⅱ or Ⅲ . The patients were unpremeditated. Epidural catheter was inserted at L2-3 or L3-4 . The local anesthetic used was 2% lidocaine. MAP,HR,HRV and SpO2 were monitored during anesthesia and operation. After onset of epidural analgesia a loading dose of midazolam(0.03 mg?kg-1 ) or propofol (0.7 mg?kg-1 ) was given i.v. followed by intermittent i.v. boluses of 1 /4-1 /2 loading dose to maintain the depth of sedation at OAA/S score of 3 (respond to name outer if called repeatedly) . Changes in HRV before and during sedation were recorded and compared between the two groups. Results The demographic data including sex, age and body weight were comparable between the two groups. LF and TP decreased significantly during sedation as compared with baseline in both groups ( P
