Brief Summary:
Can epidural nalbuphine reduce incidence or severity of epidural morphine induced pruritus in patient undergoing cesarean section?

Condition or disease Intervention/treatment Phase
Cesarean Section Drug: nalbuphine Other: NSS Phase 4

Detailed Description:

182 parturients,ASA 1-2 undergoing cesarean section under epidural block were enrolled in the study. After obtaining informed consent,all received epidural anesthesia using 2% lidocaine with epinephrine 1:200000 via epidural cathetes at L2-3 or L3-4 in a volume suffient to achieve a T4 sensory level bilaterally.

After the umbilical cord was clamped,patients were assigned randomly to three groups.The placebo group,N-5 group,and N-10 group received 4 ml epidural solution containing morphine 4 mg plus either saline, nalbuphine 5 mg, and nalbuphine 10 mg respectively.At the post anesthetic care unit, intravenous pethidine PCA were administered for inadequate pain control.

Outcome measures :

Incidence and severity of postoperative pruritus Quality of pain control Side effects of epidural morphine and nalbuphine such as respiratory depression,sedation
