Which method of pain relief is typically administered at 8-9 cm dilation in multiparous women?

The option indicating pudendal anesthesia is the correct choice because it is commonly used for pain relief during the second stage of labor, particularly in multiparous women who may be at 8-9 cm dilation. This method provides targeted pain relief to the lower birth canal and perineum, which is crucial during the pushing phase. It involves administering local anesthetic agents into the pudendal nerve, allowing women to experience effective pain management while still being able to participate actively in the birthing process.

This form of anesthesia is especially beneficial in multiparous women, who may be more familiar with the sensations of labor and prefer to have localized relief that allows them to feel in control as delivery approaches. Other methods, such as spinal anesthesia, are generally reserved for situations that require more extensive pain relief or surgical interventions, and general anesthesia is rarely used in contemporary obstetric practice due to significant risks for both the mother and baby. Nitrous oxide, while effective for pain relief, is typically used earlier in labor and may not provide the concentrated relief desired at this stage of dilation.
