The first stage of labour is divided into latent and active phases, where the latent phase is sometimes included in the definition of labour, [39] and sometimes not. [40] The latent phase is generally defined as beginning at the point at which the woman perceives regular uterine contractions. [41]
The first 6 to 12 hours after childbirth is the initial or acute phase of the postpartum period. [10] During this time the mother is typically monitored by nurses or midwives as complications can arise. The greatest health risk in the acute phase is postpartum bleeding. Following delivery the area where the placenta was attached to the uterine ...
These periods are divided into three stages. The first stage occurs in the first 30 minutes of life; during this stage the infant is alert and responsive with heart rate peaking at 160-180 beats per minute and then stabilizes to a baseline rate of 100-120 beats per minute. Crackles upon auscultation and irregular respirations are a normal finding.
In reproductive health, obstetric transition is a concept around the secular trend of countries gradually shifting from a pattern of high maternal mortality to low maternal mortality, from direct obstetric causes of maternal mortality to indirect causes, aging of maternal population, and moving from the natural history of pregnancy and childbirth to institutionalization of maternity care ...
Phase transition, a transformation of the state of matter; for example, the change between a solid and a liquid, between liquid and gas or between gas and plasma; Quantum phase transition, a phase transformation between different quantum phases; Quantum Hall transitions, a quantum phase transition that occurred because of the quantum Hall effect
In this stage of DT, countries are vulnerable to become failed states in the absence of progressive governments. Population pyramid of Angola 2005. Another characteristic of Stage Two of the demographic transition is a change in the age structure of the population. In Stage One, the majority of deaths are concentrated in the first 5–10 years ...
Prolonged labor is the inability of a woman to proceed with childbirth upon going into labor. [1] Prolonged labor typically lasts over 20 hours for first time mothers, and over 14 hours for women that have already had children. [1] Failure to progress can take place during two different phases; the latent phase and active phase of labor. [1]
As the fetal hypothalamus matures, the activation of the hypothalamic–pituitary–adrenal (HPA) axis initiates labor through two hormonal mechanisms. The end pathway of both mechanisms lead to contractions in the myometrium, a mechanical cause of placental separation, which is due to the sheer force and contractile and involutive changes that occur within the uterus, distorting the placentome.
