Chapter 6 Section 1 Notes: Labor and Birth

The Beginning of Labor Lightening: baby settles deep into pelvis; pressure on upper abdomen is lightened “Show” or “bloody show”: few drops of blood or pinkish vaginal stain; occurs when mucus that plugs uterus dissolves Plug seals cervix (lower part of uterus)

Water breaks: amniotic sac, holding fluid around baby has broken Woman should note time, amount, color and odor Delivery should happen within 24-48 hours to prevent infection Contraction: tightening and releasing of muscles in uterus; pushes fetus against cervix

Fetal monitoring: watching an unborn baby’s heart rate for indications of stress Premature birth: occurs when fetus has been developing for 37 weeks or less Real labor: when contractions follow a regular pattern and grow in intensity Induce: starting labor by artificial means; medication or puncturing amniotic sac

Stages of Labor Stage 1: Contractions open the cervix Active labor: when contractions are 60 seconds and 2-3 minutes apart Dilate: to widen or open Breech: bottom first

Stage 2: Baby is born Episiotomy: surgical cut to widen birth canal Stage 3: Placenta is expelled Placenta: organ developed to supply oxygen to fetus Cord blood: blood left behind in umbilical cord and placenta Can have cord blood stored or donated

Terms to Know Anesthesia: drugs that cause a loss of feeling Epidural blocks: injected into lower back and numb lower half of body Cesarean birth: delivery of a baby through a surgical incision in mother’s abdomen Incubator: special enclosed crib where oxygen supply, temperature, and humidity can be closely controlled
