Abstract
Background An epidural block is a superior potent approach to labour analgesia, and ropivacaine combined with fentanyl has been successfully practised for it. Dexmedetomidine, as a novel form of labour analgesia, must be researched further. Our study results give insight into the epidural block and come up with a pioneering approach for labour analgesia. Methodology A total of 68 parturients were assigned to two equal groups and received either dexmedetomidine with ropivacaine (Group RD) or fentanylwith ropivacaine (Group RF). Parturients received a loading dose and maintenance was given using a patient-controlled analgesia (PCA) pump. Analgesia onset time, labour duration, rescue dose requirement, and Visual Analogue Scale (VAS) pain scores were noted. Appearance, Pulse, Grimace, Activity and Respiration (APGAR) scores of newborns, Ramsay Sedation Scale (RSS) scores of mothers, and maternal side effects were observed. Results Group RDshowed a shorter onset time of analgesia (group RD: 12.50 ± 1.31 minutes vs. group RF: 15.26 ± 1.46 min), less local anaesthetics requirement (group RD: 47.54 ±5.37 ml vs. group RF: 59.05 ± 6.62 ml), less number of bolus doses (group RD: 0.15 ± 0.36 vs. group RF: 1.21 ± 0.95), and shorter duration from the epidural administration to the delivery (group RD: 312.97 ± 42.40 minutes vs. group RF: 345.94 ±14.67 minutes) than group RF. VAS values of the RD group were significantly less than the RF group. The RSS scores were comparably low in both groups, and excessive sedation was not seen in any group. Newborn APGAR values were comparably on the higher side in the two groups. Adverse effects were observed in the two groups, like hypotension, nausea/vomiting, bradycardia, shivering, and pruritus, which were insignificant. Conclusion The RD group showed an improved analgesic effect with a quicker onset of action,reduced requirement of local anaesthetics, and lower VAS scores compared to the RF group. With ropivacaine, dexmedetomidine shows more efficacy than fentanyl during epidural block and is a safe alternative for labour pain management.
