Description of intervention(s) / exposure
The patients ' demographic data were recorded. Patients distributed to groups with closed envelope technique. The patients divided into three groups.
according to the administered opioids that they receive:

Group II: 8 mg 5% hyperbaric bupivacaine + 20 mcg fentanyl + 50 mcg morphine were administrated intrathecal prior to caesarean procedure by anaesthesiologist
Group III: 8 mg 5% hyperbaric bupivacaine + 20 mcg fentanyl + 100 mcg morphine were administrated intrathecal prior to caesarean procedure by anaesthesiologist

The effectiveness of spinal anesthesia was assessed with the hot-cold sensation test and Bromage scale. The surgery was initiated when the sensorial block level reaches T4 dermatome. Intraoperative pain was monitored using the Visual Analog Scale (VAS). The duration of effective analgesia till the first postoperative analgesic requirements, The additional analgesic requirement within the first 24- hours after the surgery, the amount of additional analgesics, and side effects (nausea, vomiting, pruritus, and headache) were evaluated and recorded.
