To relieve pain during the second (pushing) stage of labour, an injection called a pudendal block can be given through the vaginal wall and into the pudendal nerve in the pelvis. This numbs the area between the vagina and anus. It doesn't relieve the pain of contractions.
A pudendal block works fast, is easily given, and doesn't affect the baby. It's given shortly before delivery. But it can't be used if the baby's head is too far down in the birth canal (vagina).
