Document Summary
Chapter 4 birth and the newborn infant. The first stage is divided into three phases: latent, active, and deceleration: in the latent phase, the contractions become more frequent, stronger, and gain regularity, and most of the change of the cervix involves thinning, or effacement. Most variable; up to 20 hours for 1st time; 10-12 hours for 2nd time---tends to get shorter and shorter with each child. If membranes rupture, labor speeds up: the next portion of the first stage of labor is the active phase, which is the phase of the most rapid cervical dilatation. Most predictable; 5 hours for 1st time, 2 hours for. 2nd time: finally, there is the deceleration phase (transition), during which the cervical dilation continues, but at a slower pace, until full dilation. Fetus is in the lower pelvis; vomiting, uncontrollable shaking is normal: stage two- the second stage is the delivery of the infant, during the second stage, mom actively pushes out the baby.
