INTRAA Flashcards
The first 1 to 4 hours after delivery of the newborn and placenta
Intrapartum
Refers to the medical and nursing care given to the pregnant woman during labor and delivery.
Intrapartum Care
Series of events by which uterine contractions and abdominal pressure expel a fetus and placenta from the uterus.
Labor
True or False:
Irregular contraction causes progressive dilatation of the cervix and create sufficient muscular uterine force to be pushed out into extrauterine life.
False - Regular contractions
Which theories of onset labor:
A hollow organ once stretched to its maximum potential will always contract and expel content.
Uterine Stretch Theory
Rising of fetal cortisol level reduce progesterone level which increases prostaglandin formation
Prostaglandin Theory
Increased estrogen and sudden drop in progesterone near delivery stimulates labor
Progesterone Deprivation/Withdrawal
Placenta begins to degenerate by 36 weeks where the body perceives it as a foreign body already, and make its own defense to expel it by contraction of the uterus.
Theory of Aging Placenta
The posterior pituitary gland produces oxytocin which causes contractions.
Oxytocin Stimulation Theory
Largest part of the newborn’s body and 1/4 of the newborn’s length.
Fetal head
Connects 2 parietal bones
Sagittal
Connects parietal and frontal bones
Coronal
Connects parietal and occipital bones
Lambdoidal
Overlapping of the sutures of the skull to permit passage of the head to the pelvis
Molding
Diamond in shape and measures 3x4 cm in size
Bregma (Anterior Fontanel)
Triangular in shape and measures 1x1 cm in size
Lambda (Posterior Fontanel)
Are used as landmarks for internal examination during labor to determine position of fetuses.
Fontanels
May be manipulated during delivery to allow passage.
Fetal Shoulder
Largest Transverse diameter measurement
Biparietal (9.25 cm)
Relationship of spine of fetus to spine of the mother
Lie
Fetus’ long axis parallel with mother’s long axis where 99% of cases assume this position
Longitudinal or Vertical
