1. Chapter 4 Birth and the Newborn Baby: In the New World

2. Birth and the Newborn Baby: Truth or Fiction?
The fetus signals the mother when it is ready to be born.
After birth, babies are held upside down and slapped on the buttocks to stimulate independent breathing.

3. Birth and the Newborn Baby: Truth or Fiction?
The way that the umbilical cord is cut determines whether the baby’s “belly button” will be an “inny” or an “outy.”
Women who give birth according to the Lamaze method do not experience pain.

4. Birth and the Newborn Baby: Truth or Fiction?
In the United States, 1 birth in 4 is by cesarean section.
It is abnormal to feel depressed following childbirth.

5. Birth and the Newborn Baby: Truth or Fiction?
Parents must have extended early contact with their newborn children if adequate bonding is to take place.
More children die from sudden infant death syndrome (SIDS) than from cancer, heart disease, pneumonia, child abuse, AIDS, cystic fibrosis and muscular dystrophy combined.

Countdown…
The Stages of Childbirth

7. What Events Occur just prior to the Beginning of Childbirth?
Dropping or Lightening
Head of fetus settles in pelvis
Braxton-Hicks contractions
First uterine contractions may be experienced as early as 6th month
Blood spotting in vaginal secretions
Day or so before labor
Rush of amniotic fluid from vagina
Occurs in 1 woman in 10

8. What Events Occur just prior to the Beginning of Childbirth?
Beginning of labor may be signaled by indigestion, diarrhea, ache in small or back, and abdominal cramps
Placenta and uterus secretes prostaglandins
excite uterus muscles causing contractions
As labor progresses, oxytocin is released
stimulates contractions powerful enough to expel the fetus

9. What Happens during the First Stage of Childbirth?
Uterine contractions efface and dilate cervix
First stage lasts from a few hours to more than a day
Contractions increase in strength, frequency, and regularity
Mother may be prepped
Shaving pubic hair
Administer enema

10. What Happens during the First Stage of Childbirth?
Fetal monitoring
Measure fetal heart rate and mother’s contractions
If necessary to speed up delivery, forceps or vacuum extraction tube may be used
Transition (about 30 minutes)
Cervix is nearly fully dilated
Head of fetus moves into vagina
Frequent and strong contractions

11. Figure 4.1 The Stages of Childbirth
Figure 4.1 The Stages of Childbirth. In the first stage, uterine contractions efface and dilate the cervix to about 4 inches so that the baby may pass. The second stage begins with movement of the baby into the birth canal and ends with birth of the baby. During the third stage, the placenta separates from the uterine wall and is expelled through the birth canal.
Figure 4.1 The Stages of Childbirth

12. What Happens during the Second Stage of Childbirth?
Begins when baby appears at opening of birth canal
Ends with birth of baby
Baby’s head crowned when it begins to emerge from birth canal
Episiotomy may be performed once crowning takes place
Used to prevent tearing of mother
Controversial and used less frequently

13. Lessons in Observation: Birth
In the video, Lee had her baby in a hospital setting, without fetal monitoring or anesthesia. What are some other approaches to childbirth outlined in your text?
Lee was in labor for 9 hours with her first child, Carter. Is this typical?

14. Lessons in Observation: Birth

15. Lessons in Observation: Birth
Lee and Dan were worried about the size of Carter’s testicles and his somewhat flattened facial features. Describe the newborn baby’s appearance and explain the likely duration of these characteristics.
What does the acronym APGAR stand for?

16. Lessons in Observation: Birth
How are each of the five areas tested by the APGAR rated? Appearance, Pulse, Grimace, Activity, Respiration
Explain the APGAR score ratings in connection with good, fair, and poor condition.

17. Lessons in Observation: Birth
What was Carter’s APGAR score?
Why is this test performed twice, at one minute and at five minutes?
Does the APGAR score predict the future health of a baby?

18. What Happens during the Second Stage of Childbirth?
Once baby’s head emerges from mother, mucus is suctioned from the baby’s mouth
Clears passageway for breathing
Umbilical cord is clamped and severed
Newborn may be removed
Baby is footprinted
ID bracelet is put on baby
Antibiotic ointment or drops are applied to baby’s eyes
Baby receives Vitamin K injection

19. What Happens during the Third Stage of Childbirth?
Also referred to as the placenta stage
Lasts minutes to an hour or more
Placenta separates from the wall of uterus and is expelled
Obstetrician sews episiotomy, if performed

20. Methods of Childbirth

21. How is Anesthesia Used in Childbirth?
General anesthesia
Puts mother to sleep
Negative effects of general anesthesia
Abnormal patterns of sleep and wakefulness
Decreased attention and social responsiveness for at least 6 weeks
Local anesthetics
Deadens pain without putting mother to sleep
Minor depressive effects on neonates shortly after birth

22. What is Prepared Childbirth?
Lamaze method
Utilize breathing and relaxation exercises to lessen fear and pain
Teaches women to associate relaxation with contractions
Coach
Aids the mother in the delivery room
Provides social support to mother during labor
Doula
Experienced female companion provides continuous emotional support during labor
Fewer cesarean deliveries, less anesthesia, and shorter, less painful labors

23. What is the C-section? Cesarean Section
Delivered by abdominal surgery
Physicians prefer C-section to vaginal delivery
Mother’s small pelvis
Maternal weakness or fatigue
Baby is too large
Baby is in distress
May be used to bypass infections in birth canal from HIV or Herpes

24. How Can a Woman Decide to Deliver Her Baby?
Diversity of birthing options
All-in-one labor, delivery, recovery, and postpartum rooms (LDRPs)

Parents often do not treat preterms as well as full term
Less attractive than full-term babies
High-pitched, grating cries
More irritable
Preterms and parent interaction is less even when they are brought home

31. How are Preterm Infants Treated Following Birth?
Interventions for preterm infants
