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]
The postpartum period can be divided into three distinct stages; the initial or acute phase, six to 12 hours after childbirth; subacute postpartum period, which lasts two to six weeks, and the delayed postpartum period, which can last up to six months. In the subacute postpartum period, 87% to 94% of women report at least one health problem.
Labor is separated into 4 stages. The first stage involves latent phase and active phase separated by the dilation of the cervix for 6 to 10 cm. The second stage is the pushing stage. The third stage involves the delivery of the placenta. And the last stage is the contraction of the uterus. [22]
The period of time starting just after the baby is expelled until just after the placenta is expelled is called the third stage of labor. The third stage of labor can be managed actively with several standard procedures, or it can be managed expectantly (also known as physiological management or passive management), the latter allowing the ...
The normal period of gestation (pregnancy) is about nine months or 40 weeks. The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus. The germinal stage takes around 10 days. [1] During this stage, the zygote divides in a process called cleavage.
This mitosis is also known as cleavage. A hollow cavity forms marking the blastocyst stage. (day 1.5–3 of fertilization. [1]) The blastocyst contains only a thin rim of trophoblast cells and a clump of cells at one end known as the "embryonic pole" which include embryonic stem cells.
The perinatal period (from Greek peri, "about, around" and Latin nasci "to be born") is "around the time of birth". In developed countries and at facilities where expert neonatal care is available, it is considered from 22 completed weeks (usually about 154 days) of gestation (the time when birth weight is normally 500 g) to 7 completed days ...
Teenage pregnancy is also known as adolescent pregnancy. [180] The WHO defines adolescence as the period between the ages of 10 and 19 years. [181] Adolescents face higher health risks than women who give birth at age 20 to 24 and their infants are at a higher risk for preterm birth, low birth weight, and other severe neonatal conditions.
