Document Summary
3 stages of labor: dilation, expulsion, placental. Neonatal period: transition from fetus to neonate, major changes in the body systems as they begin to function independenty, apgar scores. Regular frequency of contractions: false labor (false alarm): occasional spasms of the uterus, infrequent and irregular. Premature labor: onset of true labor prior to the whole development of the fetus. Episiotomy to enlarge passageway for baby if the vaginal canal is too small or if there is danger of perineal tearing: incision made posterior to the vagina in order to increase the size of the outlet. Decreased blood loss, much easier to suture, improved healing, and less likely for mother to experience pain or discomfort while healing. Downside: incision might extend and infect the external anal sphincter and rectum. Mediolateral: everywhere else in the world: incision 45 degree angle relative to the midline. Less likely to extend and infect the external anal sphincter and rectum.
