CH03 Birth and the Newborn Infant Flashcards
neonates
newborns
Oxytocin
a hormone released by the pituitary gland that causes increased contraction of the uterus during labor and stimulates the ejection of milk into the ducts(tube) of the breasts.
Braxton-Hicks contractions
Intermittent weak contractions of the uterus occurring during pregnancy. (false labor)
Stages of labor
- Stage 1: contractions occur about every 8-10 mins, increasing in frequency, duration, and intensity until the mother’s cervix expands.
- Stage 2: lasts abt 90 mins, the baby begins to move through the cervix and birth canal and ultimately leaves the mother’s body.
- Stage 3: lasts only a few mins, the umbilical | ˌəmˈbilək(ə)l | cord and placenta | pləˈsen(t)ə | are expelled from the mother.
Episiotomy | iˌpēzēˈädəmē |
An incision (surgical cut) sometimes made to increase the size of the opening of the vagina to allow the baby to pass.
APGAR scale
A standard measurement system that looks for a variety of indications of good health in newborns.
** Low scores indicate:
•Existing fetal problems or birth defects
•Difficulties related to the process of birth
•Temporary deprivation of oxygen (anoxia)–Wrapped umbilical cord–Pinched umbilical cord
vernix
the thick, greasy substance (like cottage cheese) that covers the newborn
bonding
close physical and emotional contact between parent and child during the period immediately following birth, argued by some to affect later real strength.
Lamaze
the method of childbirth makes use of breathing techniques and relaxation training (give pain relief without drugs)
midwife
the person trained to assist women in childbirth
Doula (doo-lah)
the person trained to provide emotional, psychological, and educational support during birth (does not replace midwife or obstetrician)
Walking epidural
A walking epidural uses the same medications as a classic epidural only in far smaller amounts. (use smaller needles and a system for administering continuous doses of anesthetic) -> permits women to move about more freely during labor and has fewer side effects than traditional epidural anesthesia.
preterm infants
Infants who are born prior to 38 weeks after conception (premature infants)
small-for-gestational-age infants
Infants who because of delayed fetal growth, weigh 90% or less of the avg weight of infants of the same gestational age (between conception & birth)
.
Age of viability
the point at which an infant can survive prematurely, to about 22 weeks- some 4 mths earlier than the term of a normal delivery.
