Objectives: The highly lipid-soluble opioids, sufentanil and fentanyl, are used in combination with low-concentration bupivacaine to provide combined spinal epidural (CSE) analgesia during labour. We designed a prospective, randomized, single-blind study to compare the efficacy of these two opioids with bupivacaine in terms of the quality of analgesia, side-effects and maternal and foetal outcome. Methods: Sixty parturients requesting labour analgesia were divided into two groups randomly. Group S (n=30) received bupivacaine heavy (2.5 mg) and sufentanil (5 mcg) intrathecally and 10 mL intermittent bolus of sufentanil 0.30 mcg/mL in bupivacaine 0.125% as epidural top-ups. Group F (n=30) received bupivacaine heavy (2.5 mg) and fentanyl (25 mcg) intrathecally and 10 mL intermittent bolus of fentanyl 2.5 mcg/mL in bupivacaine 0.125% as epidural top-ups. Duration of intrathecal and epidural analgesia, mean duration between epidural top-ups and total analgesic requirements were noted. Pain and overall satisfaction scores were assessed with a 10-point visual scale. Mode of delivery and neonatal Apgar scores were recorded. Results: Maternal demographic characteristics were comparable between the groups. Although CSE provided satisfactory analgesia in both the groups, parturients of group S had a significant prolongation of analgesia through the intrathecal route compared with parturients of group F. Incidence of caesarean, instrumental delivery did not differ between the groups. No difference in the incidence of motor blockade or cephalad extent of sensory analgesia was observed. Neonatal outcome and incidence of side-effects were similar in both the groups. Conclusion: We conclude that combined spinal epidural using sufentanil and fentanyl achieved high patient satisfaction and excellent labour analgesia without serious maternal or neonatal side-effects. Sufentanil provided a significantly longer duration of labour analgesia compared with fentanyl.
