Postpartum Hemorrhage Flashcards
(85 cards)
List the risk factors for PPH (10)
- hx of PPH
- uterine overdistension
- prolonged/dysfunctional labor
- grand multiparity: 5+ pregnancies
- low platelets: preeclampsia/thrombocytopenia
- medications that relax smooth muscle
- obesity
- asian or latin heritage (unclear reasons)
- birth procedures
- pre-existing anemia
PPH can occur without any risk factors!
How is hx of PPH a risk factor for PPH?
it doubles risk
what must be done if a postpartum pt has a hx of PPH?
alert the blood bank and ensure cross-matched blood availability
How is uterine overdistension a risk factor for PPH? (3)
- Multiple gestation (Twins or higher order multiples)
- Macrosomia (Baby >9 lbs)
- Polyhydramnios (Excessive amniotic fluid)
How is prolonged/dysfunctional labor a risk factor for PPH? (2)
- uterine muscle exhaustion
- lactic acid buildup
How is grand multi-parity a risk factor for PPH?
uterus may struggle to maintain tone
How is preeclampsia a risk factor for PPH?
- low platelets (HELLP syndrome)
- tx with uterine relaxants (ex: mag sulfate, nifedipine)
What medications that relax smooth muscle can increase risk for PPH? (3)
- anesthesia
- magnesium sulfate
- nifedipine
How is obesity a risk factor for PPH? (2)
- hormonal changes reduce oxytocin response
- higher likelihood of macrosomia
What birth procedures increase risk for PPH? (3)
- Induction or augmentation with oxytocin (especially prolonged use)
- Operative vaginal deliveries (forceps, vacuum)
- Cesarean section
what is the first intervention for PPH?
fundal massage
Blood clots in the uterus prevent ________ and mask ____ ______
prevent contractions and mask blood loss
Extra _____ ______ in pregnancy can delay detection of PPH
blood volume
What can be misleading?
slow trickling blood loss
What is a bias in maternity care that can put women at risk for PPH?
Young, healthy women may not be seen as “at risk”
What is true about vital signs and PPH?
Vital signs may remain stable until blood loss exceeds 1,000–1,500 mL
Pre-existing anemia increases danger in PPH. What lab values represent this?
Hgb <11
Hct <33%
List ways we can prevent complications from PPH (7)
- identify high risk pts early
- frequent postpartum assessments
- avoid invasive birth procedures if possible
- active management of 3rd stage of labor
- administer oxytocin immediately after delivery
- skin-to-skin contact
- early intervention
What should be done when high risk pts are identified early? (2)
- notify blood bank
- alert all caregivers
how often should postpartum assessments be done after birth?
every 15 mins in the first 1-2 hrs
What does active management of 3rd stage of labor entail? (2)
- Administer oxytocin before placenta delivery
- Gentle traction on placenta to promote detachment
Rapid placenta delivery prevents what?
excessive blood flow
When administering oxytocin immediately after delivery, what happens if there is no IV access?
give 10 units IM
why should oxytocin be given immediately after delivery?
it floods oxytocin receptors to contract uterus effectively
