Epidural Anesthesia and Postoperative Analgesia With Ropivacaine and Fentanyl
Epidural Anesthesia and Postoperative Analgesia With Ropivacaine and Fentanyl in Off-pump Coronary Artery Bypass Grafting

The aim of the present study was to assess the efficacy of thoracic epidural anesthesia followed by postoperative epidural infusion and patient-controlled epidural analgesia with ropivacaine/fentanyl in off-pump coronary artery bypass grafting

Ninety-three patients were scheduled for off-pump coronary artery bypass (OPCAB) under propofol/fentanyl anesthesia. Day before surgery patients were asked for informed consent and randomized into three postoperative analgesia regimens aiming at a visual analog scale (VAS) score <30 mm at rest. The control group (n=31) received intravenous fentanyl 10 µg/ml postoperatively 3-8 mL/h. After placement of an epidural catheter at the level of Th2-Th4 before OPCAB, a thoracic epidural infusion (EI) group (n=31) received epidural anesthesia (EA) intraoperatively with ropivacaine 0.75% 1 mg/kg and fentanyl 1 µg/kg followed by continuous EI of ropivacaine 0.2% 3-8 mL/h and fentanyl 2 µg/mL postoperatively. The patient-controlled epidural analgesia (PCEA) group (n=31), in addition to EA and EI, received PCEA (ropivacaine/fentanyl bolus 1 mL, lock-out interval 12 min) postoperatively. Hemodynamics and blood gases were measured throughout 24 h after OPCAB.

Primary Purpose: Treatment
Coronary Artery Disease
  • Procedure: intravenous analgesia
    Patients received postoperative analgesia with intravenous infusion of fentanyl 10 µg/ml 3-8 mL/h
  • Procedure: epidural infusion
    Postoperative analgesia was performed using continuous epidural infusion of ropivacaine 0.2% 3-8 mL/h and fentanyl 2 µg/mL
  • Procedure: patient-controlled epidural analgesia
    Postoperative analgesia was performed by continuous epidural infusion of ropivacaine/fentanyl mixture combined with patient-controlled epidural analgesia with ropivacaine/fentanyl bolus 1 mL, lock-out interval 12 min.
  • Active Comparator: intravenous analgesia
    Patients received postoperative analgesia by intravenous fentanyl 10 µg/ml 3-8 mL/h.
    Intervention: Procedure: intravenous analgesia
  • Active Comparator: epiduaral infusion
    Patients received epidural analgesia intraoperatively with ropivacaine 0.75% 1 mg/kg and fentanyl 1 µg/kg followed by continuous epidural infusion of ropivacaine 0.2% 3-8 mL/h and fentanyl 2 µg/mL postoperatively.
    Intervention: Procedure: epidural infusion
  • Active Comparator: patient-controlled epidural analgesia
    In addition to epidural anesthesia and epidural infusion, postoperatively patients received patient-controlled epidural analgesia with ropivacaine/fentanyl bolus 1 mL, lock-out interval 12 min.
    Intervention: Procedure: patient-controlled epidural analgesia
