ABSTRACT
Spinal anaesthesia is widely used for cesarean delivery. Its quality can be improved by intrathecal [IT] addition of opioids to local anaesthetics. For obstetric analgesia, however spinal morphine alone was relatively ineffective and plagued with side effect. Spinal anaesthesia with bupivacaine combined with sufentanil has been widely used for cesarean delivery. However, the main site of action [spinal VS central] of IT sufentanil is controversial. The aim of this study was to test the responsiveness of IT sufentanil and its relative efficacy and incidence of side effect compared with intrathecal morphine after cesarean deliveries. The study done on 90 healthy ASA I or II physical status. Patients were randomly allocated to three groups. Each group of 30 patients. They received either hyperbaric bupivacaine alone [group 1] or with morphine 0.2 mg [group 2] or sufentanil 2.5 ug [group 3]. We found that the addition of IT small dose of opioid produced a significant longer duration, better quality and excellent post operative analgesia. Sufentanil was found to be more better than morphine because of less adverse effect
