Labour is an emotional experience and involves both physiological and psychological mechanisms.The pain of labour is severe but despite this its memory diminishes with time.Labour pain has two components: visceral pain which occurs during the early first stage and the second stage of childbirth, and somatic pain which occurs during the late first stage and the second stage.The pain of labour in the first stage is mediated by T10 to L1 spinal segments, whereas that in the second stage is carried by T12 to L1, and S2 to S4 spinal segments.Pain relief in labour is complex and often challenging without regional analgesia.Effective management of labour pain plays a relatively minor role in a woman's satisfaction with childbirth.
分娩是一种情感体验,涉及生理和心理机制。分娩疼痛剧烈,但尽管如此,其记忆会随着时间而消退。分娩疼痛有两个组成部分:在分娩第一产程早期和第二产程出现的内脏痛,以及在第一产程后期和第二产程出现的躯体痛。第一产程的分娩疼痛由胸10至腰1脊髓节段介导,而第二产程的疼痛由胸12至腰1以及骶2至骶4脊髓节段传导。若无区域镇痛,分娩疼痛的缓解很复杂且往往具有挑战性。分娩疼痛的有效管理在女性对分娩的满意度中所起的作用相对较小。
