(93 cards)
Return of uterus to non-pregnant state after birth
Involution
Failure of uterus to return to normal size and condition
Subinvolution
Tissue regeneration w/o leaving a fibrous scar at site of implantation
Autolysis
What is the first process of involution?
When placenta is expelled from the uterus
What is the second process of involution?
Autolysis
*makes future pregnancies possible
The fundus is ____ the umbilicus immediately after giving birth
1-2 cm below umbilicus
Within 12 hours after giving birth, the fundus rises to _______ then it descends _____ every 24 hours
Within 12 hours after giving birth the fundus rises to UMBILICUS or SLIGHTLY ABOVE then descends 1-2 cm (FB) every 24 hours
When is the fundus non palpable?
By 2 weeks
Where is the fundus at the 9th or 10th day postpartum?
Back into pelvic cavity and non palpable
By _____ the uterus is the size it was at 20 weeks
24 hours
Where is oxytocin secreted from?
Posterior pituitary
What initiates and maintains UC?
Oxytocin
Contractions control bleeding at the placental site by _____
Compression of blood vessels
What causes the reduction in the size of uterus?
Contractions
How do we document a normal fundus?
- Midline, firm, and at appropriate location for time past delivery
- Document the firmness and position of fundus in relation to umbilicus and abdominal line
Ex: Uterus firm, midline, 2FB below umbilicus
Cramping from oxytocin release after birth (pain r/t UC)
Afterpains
T/F: Afterpains decrease when first breastfeeding
FALSE—afterpains INTENSIFY when first breastfeeding
Who is afterpains more sever in: multigravidas, primagravidas, breastfeeding clients? (SATA)
Multigravidas and breast feeding clients have more severe afterpains
When do afterpains usually resolve?
3-7 days
What are afterpains doing?
Getting the uterus back to prepregnant shape and size
What is the intervention for afterpains associated with UC?
Offer pain meds or non steroid anti-inflammatory med BEFORE breast feeding (ibuprofen)
What are some interventions to enhance contracted state of uterus?
- Empty bladder q2h
- Manual massage of relaxed uterine muscle
- Administer pitocin or methergine PRN
- Breastfeed because it releases oxytocin
How is methergine usually administered: IV or IM?
IM
Does methergine cause decrease or increase in BP?
INCREASE
