Comparison of 2% lidocaine infiltration and eutectic mixture of local anesthetics cream application before spinal needle insertion for pain reduction and assessment of maternal satisfaction levels in women undergoing cesarean section at a tertiary care setup in Pakistan: a randomized controlled trial.

Background: This study aimed to compare two analgesic pretreatment techniques for assessing pain reduction before spinal needle insertion and the subsequent patient satisfaction levels in pregnant female patients undergoing cesarean sections. Methods: Sixty pregnant female patients scheduled for elective cesarean section under spinal anesthesia were randomly assigned to two groups. The Lidocaine group received local skin infiltration with 2% lidocaine pretreatment before spinal needle introducer insertion, whereas the eutectic mixture of local anesthetics (EMLA) group received EMLA (lidocaine 2.5% and prilocaine 2.5%) cream pretreatment for at least 30 min before spinal needle introducer insertion. Subjective and objective pain scores, procedure duration, number of attempts, maternal satisfaction, and decisions regarding future numbing procedures and regional anesthesia were assessed. Results: The demographic characteristics of the patients were similar between groups. The mean visual analogue scale pain score was significantly lower in the EMLA group compared to the lidocaine group (P < 0.05). Additionally, the objective pain score was significantly lower in the EMLA group (P < 0.05). The duration of spinal block placement was significantly longer in the lidocaine group than in the EMLA group (P < 0.05). The number of attempts to perform the spinal block placement was similar in both groups. However, women in the EMLA group expressed greater overall satisfaction than those in the lidocaine group (76.7% vs. 20.0%, P < 0.05). Conclusions: Analgesic pretreatment with EMLA cream is superior to local skin infiltration with lidocaine in pregnant patients undergoing elective cesarean section under spinal anesthesia.
