Using Dexamethasone As An Adjuvant To Levobupivacaine In Epidural Anesthesia To Change The Pain Intensity And Duration In Painless Labor

Background and Objective: This is a randomized controlled trial aiming at comparing the effectiveness of levobupivacaine alone versus a levobupivacaine with dexamethasone in the epidural injection for painless labor.Patients and Methods: This is a comparative randomized controlled double-blinded clinical trial with 49 patients were included in this study, all of them were primigravidas and were during vaginal delivery with a cervical dilatation >= 4 cm. Patients were included randomly in one of two groups either Group C (26 cases) with epidural levobupivacaine 0.125% in normal saline or Group D (23 cases) with epidural levobupivacaine 0.125% in normal saline combined with dexamethasone 8 mg. The duration of a second dose request, total dose given, neonatal outcome and adverse effects of epidural were recorded.Results: Group D showed a longer duration of analgesia than Group C (80.5 +/- 12.39 min in Group D vs. 61.75 +/- 10.74 min in Group C) with a P < 0.05 (0.001). Furthermore, the patients in Group D received smaller dose of levobupivacaine than those in Group C with a statistically significant difference (90.87 +/- 33.42 vs. 127.21 +/- 40.68 mg with P = 0.002). There were no statistical differences between the two groups regarding hemodynamics, pain score, neonatal outcome, and complications.Conclusion: Dexamethasone in epidural analgesia for painless labor has a prolonged duration of analgesia with no complications for both the mother and the infant.
