T3 - Maternal Physiologic Changes (Josh) Flashcards
— is return of uterus to non-pregnant state after birth .
— is failure of uterus to return to normal size and condition
Involution
Subinvolution
What is the first process to take place when the placenta is expelled from the uterus?
Uterine Involution
What is Autolysis?
tissue regeneration w/out leaving a fibrous scar at site of implantation
What is the second process of involution?
Autolysis
***makes implantation of future pregnancies possible
Where is the Fundus immediately after birth?
1-2 cm below the umbilicus
What happens to the Fundus within 12 hrs post-birth?
rises to umbilicus (or slightly above) then descends 1-2 cm (fingerbreath) every 24 hours
When would we expect the fundus to be nonpalpable?
by 2 wks
When the fundus starts descending, what is the rate of descent/
1-2 cm (fingerbreaths) q 24 hrs
By the — postpartum day, the fundus is back into the pelvic cavity and non-palpable.
9th or 10th
By 24 hours, the uterus is the size it was at — gestation.
20 wks
Where is oxytocin secreted?
Posterior Pituitary
— initiates and maintains uterine contractions.
Oxytocin
What do contractions do post-birth?
control bleeding at placental site by compression of blood vessels
reduce size of uterus
What should fundus assessment be post-delivery?
midline
firm
appropriate location for time past delivery
Where would the fundus be on PP day 3, 10 and 6 wks?
PP day 3: 2-3 fingerbreaths below umbilicus, firm, midline
PP day 10: non palpable
PP 6 wks: back to non-pregnant location
Who are afterpains (associated w/ contractions) more severe with?
multigravidas
breast feeding clients
What interventions for afterpains?
offer pain meds or NSAIDs (ibuprofen) BEFORE breast feeding
What causes afterpains?
cramping from oxytocin release after birth
***intensifies w/ breastfeeding
— is responsible for milk production.
— is responsible for milk letdown.
Prolactin
Oxytocin
What enhances milk let down?
comfort and relaxation
When would afterpains resolve?
3-7 days
***assure client that afterpains are helping uterus return to prepregnant size and shape
Interventions to enhance contracted state of uterus?
Empty bladder q 2hr
Manual massage or relaxed uterine muscle
Pitocin or Methergine
Breast feeding
When would Methergine be contraindicated?
BP 140/90
***causes increased BP
When is Lochia Serosa?
days 4-9
When is Lochia Alba?
days 10-14
When is Lochia Rubra?
days 1-3
Normal Lochia Rubra:
Bright red
SMALL clots
Blood, decidual & trophoblastic debris
Normal Lochia Serosa:
Pink/Brownish
Decreases over time
Serum, leukocytes, tissue debris & old blood
Normal Lochia Alba:
Creamy
Disappears over time
Leukocytes, epithelial cells, mucous, serum & bacteria
Signs of Uterine Infection
Lochia has an offensive odor
Lochia reverts to an earlier stage of color/amount
Lochia persists beyond normal time
Documenting bleeding amount:
Scant =
What is classified as hemorrhage post-partum?
blood loss of 500 mL or greater
***can be early or late
