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]
At the end of the luteal phase, progesterone levels fall and the corpus luteum atrophies. The drop in progesterone leads to endometrial ischemia which will subsequently shed in the beginning of the next cycle at the start of menses. [1] This last stage in the luteal or secretory phase may be called the ischemic phase and lasts just for one or ...
Regional anaesthesia during caesarean section is different from the analgesia (pain relief) used in labor and vaginal delivery. [84] [85] [86] The pain that is experienced because of surgery is greater than that of labor and therefore requires a more intense nerve block. General anesthesia may be necessary because of specific risks to mother or ...
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 ...
The resultant age is known as fertilization age, fertilizational age, conceptional age, embryonic age, fetal age or (intrauterine) developmental (IUD) [29] age. Gestational age , in contrast, takes the beginning of the last menstrual period (LMP) as the start point.
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 ...
