More specifically, labor requires regular, effective contractions that lead to dilation and effacement of the cervix. This chapter describes the physiology and normal characteristics of term labor and delivery.
A normal delivery starts spontaneously and has only low risks identified at the start of labour. This situa-tion (with regard to continuously assessed risks) lasts throughout labour and delivery. The child is born spontaneously in vertex position between 37 and 42 weeks of gestation.
1 mar 2020 · For the purposes of this review, we will outline the biochemical, hormonal and mechanical phases of normal spontaneous labour and vaginal delivery, before describing how these may be influenced at different points by intervention, or by the risk status of the labouring woman.
6 wrz 2024 · The World Health Organization (WHO) defined normal birth as "spontaneous in onset, low-risk at the start of labor and remaining so throughout labor and delivery. The infant is born spontaneously in the vertex position between 37 and 42 completed weeks of pregnancy.
Five care practices promote the normal physiological process: allowing labor to start on its own, freedom of movement during labor, continuous labor support, spontaneous pushing in nonsupine positions, and no separation of mother and baby.
4 kwi 2023 · Introduction. Normal labour may be interpreted differently depending on the experience and expectations of the birthing person and clinical care provider. For some, normal labour may be synonymous with spontaneous labour, leading to vaginal birth of an infant without intervention.
18 cze 2018 · To estimate the probability of a normal birth we multiplied the estimated probabilities from the four logistic models (the probabilities of a spontaneous onset of labour, no anaesthesia, an unassisted vaginal birth, and no episiotomy).
