World
2Countdown
3What 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
4What 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
5What 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
6What Happens during the First Stage of Childbirth?
- Fetal monitoring
- Measure fetal heart rate and mothers
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
7Figure 4.1 The Stages of Childbirth
8What Happens during the Second Stage of
Childbirth?
- Begins when baby appears at opening of birth
canal - Ends with birth of baby
- Babys 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
9What Happens during the Second Stage of
Childbirth?
- Once babys head emerges from mother, mucus is
suctioned from the babys 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
babys eyes - Baby receives Vitamin K injection
10What 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
11Methods of Childbirth
12How 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
13What 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
14What is the C-section?
- Cesarean Section
- Delivered by abdominal surgery
- Physicians prefer C-section to vaginal delivery
- Mothers 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
15How Can a Woman Decide to Deliver Her Baby?
- Diversity of birthing options
- All-in-one labor, delivery, recovery, and
postpartum rooms (LDRPs) - Birthing suite in hospital equipped for
uncomplicated birth - Easy access to emergency facilities if needed
- Home Birth
- Can be fairly safe for healthy women with little
risk of complications
16Birth Problems
17What are the Effects of Oxygen Deprivation at
Birth?
- Hypoxia - Prenatal oxygen deprivation
- can impair development of central nervous system
and psychological disorders - Anoxia - Oxygen deprived at birth
- predicted problems in learning and memory
- can cause health problems such as early-onset
schizophrenia and cerebral palsy
18What is Meant by the Terms Prematurity and Low
Birth Weight?
- Premature or preterm baby
- Occurs before 37 weeks gestation (normal is 40
weeks) - Low-birth-weight baby
- Weighs less than 5.5 pounds
- Small for date
- Low-birth-weight, although born at full term
19What Risks are Connected with being Born
Prematurely or Low in Birth Weight?
- Infant mortality
- Neonates weighing 3.25 to 5.5 pounds are 7 times
more likely to die than infants of normal weight - Those weighing less than 3.3 pounds are nearly
100 times as likely to die - Delayed neurological development
- Lower birth weight poorer performance
throughout school years - Delayed motor development, such as walking
- Preschool experience fosters cognitive and social
development
20What Signs are Connected with being Born
Prematurely or Low in Birth Weight?
- Preterm babies show signs of immaturity
- relatively thin
- fine, downy hair (lanugo)
- oily, white substance on skin (vernix)
- Preterms born six weeks or more prior to full
term - nipples not yet be emerged
- testicles of boys not yet descended into scrotum
- Muscles immature and reflexes are weak
- Respiratory distress syndrome
- walls of air sacs in lungs stick together
21How are Preterm Infants Treated Following Birth?
- Usually remain in hospital incubators
- Temperature-controlled environment with
protection from infection - 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
22How are Preterm Infants Treated Following Birth?
- Interventions for preterm infants
- Benefit from external stimulation
- Massage
- Kangaroo care
- Preterm infants exposed to stimulation
- Gain weight more rapidly
- Show fewer respiratory problems
- Make greater advances in motor, intellectual, and
neurological development than controls
23Developing in a World of Diversity
- Maternal Mortality and Infant Mortality Around
the World
24The Postpartum Period
25What Kinds of Problems in Mood do Women
Experience during Postpartum Period?
- Baby blues
- Transient about 10 days
- Postpartum depression (PPD)
- Begins one month after delivery and may linger
for weeks/months - Major depressive disorder
- Psychotic features
26How Critical is Parental Interaction with
Neonates in the Formation of Bonds of Attachment?
- Bonding
- Formation of bonds of attachment between parent
and child - Essential to survival and well being of child
- Maternal sensitive period
- Amount of access to newborn (Klaus Kennell,
1978) - Extended early contact is not essential for
adequate bonding
27Characteristics of Neonates
28How do Health Professionals Assess the Health of
Neonates?
- Apgar scale
- Based on five signs of health
- Interpretation of scores
- 7 or above no danger
- below 4 critical condition
- Brazelton Neonatal Behavioral Assessment Scale
- Based on four areas of behaviors
- Measures reflexes, motor behavior and muscle tone
29What are Reflexes?
- Reflexes
- Simple, unlearned stereotypical responses,
elicited by certain types of stimulation - Survival value
- Neural functioning is determined by testing
reflex
30What Kinds of Reflexes are Shown by Neonates?
- Rooting
- Baby turns head and mouth toward stimulus that
strokes the cheek, chin, or corner of mouth - Facilities finding mothers nipple for sucking
- Sucking
- Babies will suck almost any object that touches
the lips - Will become replaced by voluntary sucking
31What Kinds of Reflexes are Shown by Neonates?
- Moro or startle reflex
- Back arches, legs and arms are flung out and then
brought back toward chest into a hugging motion - Occurs when babys position is suddenly changes
or health and neck support is lost - Elicited by loud noises or bumping baby
- Usually lost 6 to 7 months after birth
32What Kinds of Reflexes are Shown by Neonates?
- Grasping or palmar reflex
- Using four fingers, babies grasp fingers/objects
pressed against the palms of their hands - Most babies can support their own weight
- Usually lost by 3 to 4 months
- Replaced by voluntary grasping at 5 to 6 months
33What Kinds of Reflexes are Shown by Neonates?
- Stepping reflex
- Mimic walk when held under arms
- Usually disappears by 3 or 4 months
34What Kinds of Reflexes are Shown by Neonates?
- Babinski reflex
- Fans or spreads toes in response to stroking foot
- Usually disappears at end of first year
- Tonic-neck reflex
- While lying on back, baby turns head to one side.
Arm and leg on that side extend, while opposite
side flex.
35Vision
- Visual acuity
- Estimate of 20/600
- Best see objects 7 to 9 inches from eyes
- Lack peripheral vision of older child
- Able to track movement within one day of birth
- preference for moving objects
36A Closer Look
- Studying Visual Acuity in Neonates How Well Can
They See?
37Vision
- Visual accommodation
- Self-adjustments made by eye lens to bring
objects into focus - Neonates show little or no visual accommodation
- Focus on objects 7 to 9 inches away
- Convergence
- Does not occur until 7 or 8 weeks
38Hearing
- Fetuses respond to sound

- Demonstrate aversion for noxious and preference
for pleasant odors - Recognize familiar odors
- Taste
- Sensitive to different tastes
- Demonstrate facial expressions to basic tastes
- Prefer sweet tastes
40Touch and Pain
- Touch
- Sensitive to touch
- Touch elicits many reflex behaviors
- Pain
- Less sensitive to pain
41Learning
- Or Really Early Childhood Education
42Can Neonates Learn?
- Classical Conditioning
- Involuntary responses are conditioned to a new
stimuli - Operant Conditioning
- Behavior (reflexes) are modified through
reinforcement
43What Patterns of Sleep are Found among Neonates?
- Neonates spend about 16 hours per day in sleep
- Typical infants has six cycles of waking and
sleeping - REM Sleep
- Neonates spend 50 time in REM sleep

- 2 to 3 years 20 to 25
- NREM Sleep
44Figure 4.15 REM Sleep and Non-REM Sleep
45Why do Babies Cry?
- Pain and discomfort
- Universal, expressive and functional
communication - expressive response to unpleasant feelings
- stimulates caregiver response
- Distinct causes and patterns of cries
- Hunger, anger, pain
- Peaks of crying in late afternoon and early
evening - Crying produces physiological response in others
46What Can I do to Stop an Infant from Crying?
- Sucking serves as a built-in tranquilizer
- Pacifier, sweet solutions
- Soothing processes
- Pick baby up, patting, caressing, rocking them
- Speaking to them in low voice
47What is SIDS?
- Sudden Infant Death Syndrome crib death
- Strikes while the baby is sleeping
- Most common cause of death in infants between 1
and 12 months - Most likely to occur between 2 and 5 months
