The effect of addition of dexamethasone to levobupivacaine in parturients receiving combined spinal-epidural for analgesia for vaginal delivery.

ABSTRACT: Regional analgesia is commonly used for the relief of labour pain, Prolongation of analgesia can be achieved by adjuvant medications. The aim of this randomised controlled trial was to evaluate the efficacy of intrathecal levobupivacaine with dexamethasone for labour analgesia.A total of 80 females were included in this study, all were primigravidas undergoing vaginal delivery with cervical dilatation ≥4 cm and 50% or more effacement. Forty females were included randomly in either Group L (received intrathecal levobupivacaine 0.25% in 2 mL) or Group LD (received intrathecal levobupivacaine 0.25% combined with dexamethasone 4 mg in 2 mL). The primary outcome was the duration of spinal analgesia. Secondary outcomes included the total dose of epidural local anaesthetic given, time to delivery, neonatal outcome and adverse effects.The duration of spinal analgesia was significantly longer in the LD group compared with L group (80.5 ± 12.4 min vs. 57.1 ± 11.5 min, respectively; P < 0.001). In Group LD compared with Group L, time from spinal analgesia to delivery was significantly lower (317.4 ± 98.9 min vs. 372.4 ± 118.8 min, respectively; P = 0.027), and total epidural levobupivacaine consumption was significantly lower (102.4 ± 34.8 mg vs. 120.1 ± 41.9 mg, respectively; P = 0.027). The two groups were comparable with respect to characteristics of sensory and motor block, haemodynamic parameters, pain scores, neonatal outcome and frequency of adverse effects.Intrathecal dexamethasone plus levobupivacaine prolongs the duration of spinal analgesia during combined spinal-epidural CSE for labour analgesia.
