简要总结
This study investigates efficacy, safety and childbirth experience in women receiving pudendal block during the final stage of delivery. It is an observational study and half of included primarous women recieve a pudendal block.
详细描述
Pudendal block is used when there is a need to alleviate pain in the final stage of labour:
- From fully dilated cervix to delivery of the child.
- Associated with pain as the foetus rotates and descends through the pelvis.
- End of second stage: the perineum dilates as the child is being born.
Pudendal block is provided by inserting a needle close to the pudendal nerve that runs through the pelvis and innervates the perineal area.Pudendal block is an old and relatively simple method, but not well studied. The main aim is to study pudendal nerve block as pain relief in final stage of labour for primiparous women delivering vaginally.
The investigators aim to investigate whether possible adverse effects may outweigh the positive analgesic effect in the final stage of labour, or the opposite. The ASL (Analgesia in the Second stage of Labour) study may fill knowledge gaps and add important knowledge regarding pain relief during the final stage of childbirth.
