Topics • Understanding Childbirth • Delivery • Complications and Emergencies
Understanding Childbirth • Anatomy of Pregnancy • Fetus: unborn baby • Ovum: unfertilized egg produced by the mother • Uterus: muscular structure that holds baby during pregnancy • Full term: pregnancy achieved complete gestation of between 38 and 40 weeks (continued)

Understanding Childbirth • Anatomy of Pregnancy • Trimester: three months of pregnancy • Labor: process body goes through to deliver fetus • Cervix: opening of uterus • Bloody show: normal discharge of bloody mucus prior to delivery • Vagina: birth canal (continued)
Understanding Childbirth • Anatomy of Pregnancy • Crowning: showing of baby's head at opening of vagina. • Imminent delivery: delivery that is likely to occur within a few minutes. • Amniotic sac: fluid-filled sac that surrounds developing fetus. • Rupture of membranes: sac breaks during labor; the fluid flows out of vagina. (continued)
Understanding Childbirth • Anatomy of Pregnancy • Placenta: organ of pregnancy that serves as filter between mother and developing fetus. • Umbilical cord: structure that connects baby to placenta.
Understanding Childbirth • Stages of Labor • First stage: begins with onset of regular contractions; ends when cervix is fully dilated allowing baby to enter birth canal. • Second stage: begins when baby enters birth canal; ends when born. (continued)

Understanding Childbirth • Stages of Labor • Third stage: begins when baby is born; ends when placenta (afterbirth) delivered. • Normal to have vaginal discharges throughout labor. • Contractions of uterus cause labor pains.

Understanding Childbirth • Stages of Labor • Contraction time: span of time from beginning of contraction until it relaxes. • Interval time: span of time from start of one contraction to beginning of next contraction. • Braxton Hicks contractions (false labor): not as regular and rhythmic as true labor contractions.
Measure the contraction intervals by counting the beginning of one contraction to the beginning of the next contraction.
Understanding Childbirth • Supplies and Materials • Personal protective equipment • Towels, sheets, blankets; gauze pads • Rubber bulb syringe; clamps and ties • Sterile scissors or single-edged razor • Sanitary pads or bulky dressings • Basin and plastic bags • Red, plastic biohazard bags
Think About It • You respond to the home of a young couple expecting their first child. They had planned to deliver at home, but grew nervous when the pain of labor became too strong. • What questions will you include in your assessment? • How will you proceed?
Delivery • Preparing for Delivery • Wear PPE. • EMS activated. • Encourage patient to remain lying down. • Place clean sheets or towels under buttocks. • Obtain medical history of pregnancy. (continued)
Delivery • Preparing for Delivery • If mother is having contractions two minutes apart or less, delivery is imminent. • Find out if she has taken a childbirth preparation class. • Control scene so mother has privacy. • Position mother on back with knees bent, feet flat, legs spread wide apart. (continued)
Delivery • Preparing for Delivery • Feel abdomen for contractions. • Prepare mother for examination. • Check for crowning. • Do not attempt any type of internal or vaginal exam.
Delivery • Normal Delivery • Crowning evident as head emerges from vagina. • Use both hands to support head as it delivers; check neck for umbilical cord. • Guide baby's head downward to facilitate delivery of top shoulder. • Use both hands to support baby following delivery. (continued)
Use both hands to support the head as it delivers and check the neck for presence of the umbilical (nuchal) cord.
Guide the baby's head downward to facilitate delivery of the top shoulder.

Delivery • Normal Delivery • Dry baby and cover to conserve heat. • Clamp cord in preparation for cutting. (continued)

Once the cord has stopped pulsating, clamp it in preparation for cutting.
Delivery • Normal Delivery • Cut cord between the clamps. • Assess breathing and pulse rate for newborn. • Expect delivery of placenta 20 to 30 minutes following delivery of baby.
