Postpartal Care Flashcards
Postpartum
Involution:
Fundal descent:
Cervix:
INVOLUTION- return of reproductive organs to pre-pregnancy size and condition.rapid reduction in size of the uterus and return to a condition similar to pre-pregnant state
FUNDAL DESCENT- descends @ 1 cm/day for 10 days after birth. Breastfeeding and an empty bladder facilitate fundal descent and involution.Within 6-12 hrs after birth the fundus rises to the level of the umbilicus. A fundus that is above the umbilicus and boggy is associated with excessive bleeding.
CERVIX- regains its shape by 18 hours after birth.
Lochia
uterine/vaginal discharge after birth.uterus ability to rid itself of debris remaining after birth.
Lochia Rubra- first three days, mostly blood with pieces of decidua and mucus. dark red color; present for 2-3 days postpartum, should not contain large clots.
Lochia Serosa- fourth day amount decreases and color changes to pink/pinkish brown. pinkish to brownish color, follows from about 3-10 day.
Lochia alba- after 10th day, discharge becomes yellowish white. May last for 6 weeks or more.
THREE STAGES OF FETAL DEVELOPMENT
- Pre-embryonic/germinal; first fourteen days.
- Embryonic; day fifteen through week eight.
- Fetal; week nine to full term (38-40 wks)
UMBILICAL CORD
21 inches in length. Contains 2 umbilical arteries that carry deoxygenated blood from the fetus to the mother and 1 vein carrying oxygenated blood. All vessels are surrounded, protected by Wharton’s jelly.
eliminates waste and carbon dioxide from the infant and deliver nutrients, hormones, antibodies etc to the fetus.
The placenta secretes five hormones that are essential to pregnancy. What are they?
What are the 3 functions of placenta?
Placenta develops in response to progesterone secreted by the corpus luteum.
Three major functions: transport, endocrine, and metabolic.
- HCG- human chorionic gonadotropin: responsible for positive pregnancy tests.
- estrogen
- progesterone
- Relaxin.
- HPL human placental lactogen
The placenta also produces fatty acids, glycogen, and cholesterol for fetal use and hormone production.
Changes in respiratory system after birth
during birth the fetal chest is compressed and fluid is squeezed from the lungs and intrathoracic pressure increases.
Chest recoil at birth creates negative intrathoracic pressure which stimulates air movement into the lungs and fluid movement into the interstitial tissue.
Change in temperature from intrauterine to extrauterine stimulates breathing too.
Changes in circulatory system after birth
lower pulmonary resistance aids blood flow to the lungs to be oxygenated.
Ductus arteriosus has a reversal of blood flow because of increased aortic pressure and increased O2 in the blood.
Pressure in the R atrium decreases and the L atrium increase. Blood flow to the liver begins and filtration of the blood begins.
• Thermoregulation after birth. Heat is lost through four mechanisms:
o Convection- heat flows from the body surface to cooler surrounding air.
o Conduction- heat transfer to a cooler solid object in direct contact.
o Radiation- body heat transfer to a cooler solid object not in contact.
o Evaporation- heat loss through conversion of a liquid to vapor.
{heat is generated through metabolism, muscular activity and nonshivering thermogenesis (metabolism of brown fat). }
Changes in Gastrointestinal system after birth
sterile at birth, does not provide necessary bacteria to synthesis vitamin K.
Limited ability to digest fat and starch.
Immature cardiac sphincter allows for easy regurgitation.
First stool is meconium, thick, sticky and tar-like.
Hyperbilirubinemia
Excessive bilirubin in the blood. Can cause yellow staining in the brain (kernicterus) at levels of 20/mg/dL.
Common cause Rh incompatibility.
Phototherapy and fluid intake are used to treat jaundice.
Respiratory distress-in newborn
Transient tachypnea that is the result of the newborn’s failure to clear the airway of fluid and mucus or aspiration of amniotic fluid.
Treatment is supportive and may include humidified O2, CPAP or mechanical ventilation.

Preterm infant-what are increased risks?
higher risk for respiratory distress syndrome, hypoglycemia and intracranial hemorrhage.
Post-term infants- risks?
beyond 42 weeks the placenta loses its ability to effectively carry nutrients to the fetus.
Newborn risk for infection
(GBS) group B streptococcal organism. Symptomatic infants (lethargy, fever, loss of appetite, increase ICP) receive antibiotics (ampicillin, gentamicin or penicillin)
Hypoglycemia risk in newborns
Serum glucose less than 40 mg/dL. Infants at risk include born to diabetic mothers, large for gestational age infants.
Treatment feed early with formula or admin IV glucose, bolus not recommended.
Risk of cold stress in newborn
Keep in warm environment to prevent increased O2 needs due to increased metabolism to stay warm.
Feta alcohol syndrome
FAS- growth restriction, CNS depression, cognitive impairment etc demonstrated with tremors, fidgetiness, and irritability.
Weak sucking reflex and sleep disturbances.
Which meds must be given soon after birth?
• Vitamin K- intestine is sterile and cannot synthesize initially after birth. Needed for clotting process.
Most newborns produce enough by day 8. Given within first hour of birth to prevent hemorrhagic disorders.
- Hep B vaccine should be given within 12 hours of birth.
- Erythromycin administered as prophylactic ophthalmic ointment. It is mandatory in the United States. May be delayed to promote bonding and attachment.
NEONATE-
birth through the first 28 days of life.
Timing of APGAR SCORING
assessment of wellness of newborn at 1 minute and repeated at 5 minutes.
