Needle phobia can affect routine prenatal care, increase the demand for general anesthesia during c-section, and increase post-op pain. During epidural placement, providers use local anesthetic in various methods to numb the area where the needle will be inserted. Pain from these anesthetic administrations can increase needle phobia and their side effects.\n\nOne use of local anesthetic is the lidocaine patch, and studies have shown it is effective in reducing pain level in patients \\[6, Firmani\\]. The transdermal lidocaine patch may lower the physical pain and mental effects of needle phobia in pregnant women and lower the side effects from that. Although lidocaine patch may take more time to numb the skin, a high number of expecting mothers will not require an epidural for labor analgesia right away. Therefore, administration of lidocaine patch might be an effective alternative.\n\nPregnant women needing epidural placement will be randomized into three groups, the lidocaine patch group, intradermal anesthetic group, or use of both to determine the effectiveness of the lidocaine patch compared to the intradermal administration.",[108],"Lidocaine Patch","2026-07-08",{"date":111,"type":112},"2026-07-13","ACTUAL",{"date":114,"type":112},"2026-06-29",{"date":116,"type":102},"2029-01-31",{"name":5,"class":6},1]
