Document Summary
Chapter 4 birth and the newborn infant. The first stage of labor is the longest. Typically labor takes 16-24 hours for firstborn children. During this stage, the uterine contractions initially occur around every 8-10 mins and last about. As labor proceeds, the contractions occur more frequently and last longer. Final part of the first stage, the contractions increase to their greatest intensity- transition. The baby"s head emerges further from the mother with each contraction, incresaing the size of the vaginal opening. Because the area between the vagina and rectum must stretch a good deal, an incision called an episiotomy is sometimes made. This stage ends when the baby has completely left the mother"s body. This is when an episiotomy may be administered an incision sometimes made to increase the size of the opening of the vagina to allow the baby to pass. Occurs when the child"s umbilical cord and the placenta are expelled from the mother.
