简要总结
To compare combined spinal epidural, epidural and IV pethidine analgesia and their effects on the mother, fetus, newborn and the course of labor.
详细描述
This is a prospective parallel single blind study, which was approved by the institutional review board of El-Galaa Teaching Hospital, and the research and ethics committee of Faculty of Pharmacy, Cairo University.
This hospital per si was selected for the study because it is large hospital that could provide the study with a diverse population. It has a population of various socio-economic statuses. This would provide the study with a sample of patients with a wide range of characteristics.
Sixty full-term, ASA physical status I or II nulliparous women in active labor with cervical dilatation of 5 cm and cephalic presenting fetus were randomly assigned to one of five groups after providing informed consent.
- Group 1: received CSE analgesia, where 25 µg of fentanyl was injected intrathecally and a bolus dose of 10 ml of 0.5% lidocaine was injected epidurally. E top-ups of 5-10 ml of 0.5-0.8% lidocaine were then injected upon request.
- Group 2: received CSE analgesia, where 25 µg of fentanyl was injected intrathecally and a bolus dose of 10 ml of 0.0625% bupivacaine was injected epidurally. E top-ups of 5-10 ml of 0.0625-0.25% bupivacaine were then injected upon request.
- Group 3: received 50µg of E fentanyl analgesia which was injected intrathecally and a bolus of 10 ml of 0.5% lidocaine was administered through the catheter, followed by lidocaine E top-ups of 5-10 ml of 0.5-0.8% upon request.
- Group 4: received analgesia, where 50 µg of E fentanyl were injected intrathecally and a bolus dose of 10 ml of 0.125% bupivacaine was administered through the catheter, followed by E bupivacaine top-ups of 5-10 ml of 0.125-0.25% upon request.
- Group 5: 50 mg of IV pethidine was administered as a loading dose, followed by 0.5 mg/kg, with a total maximum limit of 130 mg.
Study Subjects Excluding Criteria Patients who had diabetes mellitus, neurological disease, pre-eclampsia, or patients who had received parenteral analgesics or patients with contraindication to E or spinal analgesia, or patients with sensitivity to local anesthetics or opioids were excluded from the study.

结局指标
主要结局
Visual Analogue Scale to assess pain control
时间窗: 24 hours
The Visual Analogue Pain Scale (VAS) (0 mm = no pain, 100 mm = worst pain imaginable) was measured before administration of analgesia, 10 and 30 minutes after administration of each analgesic dose until the delivery of the baby.
次要结局
- The degree of motor block(24 hours)
- Adverse effects(24 hours)
- Number of top-ups(24 hours)
- Labour Duration(24 hours)
