Second stage of labor starts when the cervix is dilated to 10 cm and finishes with the birth of the baby. This stage is characterized by strong contractions and active pushing by the mother. It can last from 20 minutes to 2 hours. [16] Third stage of labor starts after the birth of the baby and is finished when the placenta is delivered. [15]
Henci Goer, in her comprehensive book, The Thinking Woman's Guide to a Better Birth, details how this practice was researched in two separate studies of 100 and 200 women in the mid nineteen-eighties. Women were assigned randomly to two groups. In one group, nipples were stimulated for one-hour sessions, three times per day.
Vacuum extraction (VE), also known as ventouse, is a method to assist delivery of a baby using a vacuum device. It is used in the second stage of labor if it has not progressed adequately. It may be an alternative to a forceps delivery and caesarean section. It cannot be used when the baby is in the breech position or for premature births.
[36] [37] The second phase of labor begins when the cervix has dilated to 10 cm (4 in), which is regarded as its fullest dilation, [32] and is when active pushing and contractions push the baby along the birth canal leading to the birth of the baby. [35]
In the US, the definition of active labour was changed from 3 to 4 cm, to 5 cm of cervical dilation for multiparous women, mothers who had given birth previously, and at 6 cm for nulliparous women, those who had not given birth before. [45] This was done in an effort to increase the rates of vaginal delivery. [46]
Dilation (or dilatation) and curettage (D&C) refers to the dilation (widening or opening) of the cervix and surgical removal of sections and/or layers of the lining of the uterus and or contents of the uterus such as an unwanted fetus (early abortion before 13 weeks), remains of a non-viable fetus, retained placenta after birth or abortion as well as any abnormal tissue which may be in the ...
The absolute risk of such birth-related perinatal loss is comparable to the risk for women having their first birth. [1] Planned VBAC carries an 8/10,000 risk of the child developing hypoxic ischaemic encephalopathy, but the long-term outcome of the infant with HIE is unknown and related to many factors. [1]
Some of these efforts are: emphasizing a long latent phase of labor is not abnormal and not a justification for C-section; a new definition of the start of active labor from a cervical dilatation of 4 cm to a dilatation of 6 cm; and allowing women who have previously given birth to push for at least 2 hours, with 3 hours of pushing for women ...
