Abstract:
Objective To assess the analgesic effect of continuous infusion of 0.2% ropivacaine with epidural catheter placed at T11-12 or L2-3 after abdominal hysterectomy. Methods Eighty ASA Ⅰ -Ⅱ patients undergoing elective abdominal hysterectomy were randomly divided into 4 groups with 20 patients in each group : in group Al and A2 the epidural catheter was placed at T11-12 and in group Bl and B2 at L2-3 . After surgery two infusion pumps were used. The first pump was used for continuous epidural infusion of 0.2% ropivacaine in the 4 groups. The second pump was used for patient controlled intravenous analgesia (PCIA) with 0.08% lornoxicam in group Al and Bl or with 0.1% morphine in group A2 and B2. The PCIA bolus dose was 1 ml with a lockout time of 5 min. The analgesic effect (assessed using VAS) and the consumption of lomoxicam / morphine were compared among the four groups. Results The ropivacaine consumption was 192 mg during the 24 h after operation in the 4 groups. The lornoxicam and morphine consumption were (3.9?2.8) mg and (4.6?3.5) mg in group Al and A2 with the epidural catheter placed at T11-12 and (7.7?2.5) mg and (7.8?2.4) mg in group B2 and B2 with catheter placed at L2-3.The consumption of lomoxicam or morphine was significantly less with epidural catheter placed at T11-12 than that with epidural catheter at L2-3 (P
