post partum hemorrhage Flashcards
definition of post-partum hemorrhage
>500mL for vaginal delivery
>1000mL for Cesarean livery
what is uterine atony?
lack of myometrial contraction, clinically manifested by a boggy uterus
methylergonovine maleate - what is it?
an ergot alkaloid agent that induces myometrial contraction as a tx of uterine atony, C/I in hypertension
prostaglanding compound that causes smooth muscle contraction that is C/I in asthmatic pts
prostaglandin F2-alpha
what is the MCC of early post-partum hemorrhage?
uterine atony
what is the management of post partum hemorrhage
- uterine massage (bimanual compression w/an abdominal hand as well as vaginal hand) + **IV dilute oxytocin ** is given
- if bleeding continues —>pharmacological uterotonic agents (ergot alkaloids, prostaglandin F2 alpha or misoprostol)
- if cont. to bleed: two large bore IVs, foley catheter, call for blood, monitor vitals, move pt to OR intrauterine balloon or embolization if patient is stable.
- if continued bleed, then laparotomy -
other cause of PPH that if uterine is firm and contracted?
- genital tract lacerations
- uterus - uterine inversion
- placental causes - placenta accret or retained placenta
- coagulopathy
what is late PPH? MCC
PPH occuring after 1st 24 hours and may be caused by involuation at the placental site.
MCC? retained products of conecption
MCC of PPH?
uterine atony
MCC of early PPH with well-contracted utersus?
genital tract lesion
MCC of late postpartum hemorrhage (after 1st 24 hours)?
subinvolution of the uterus
C/I for ergot alkaloids?
C/I for prostaglandin F2-alpha?
ergots - HTN
Prostaglandins - asthma
eval and tx of PPH –> what should you do first?
- stabilization of the circulatory status
- address the hemorrhage
how do you stabilize a patient with PPH?
address the ABCs
assure large bore IV infusion of isotonic crystalloid, assuring availability of blood products if needed and constantly monitoring key hemodynamic parameters
etiology of PPH?
- uterine atony
- genital tract lacerations —>inspect to discern whether the bleeding is supracervical, cervical,or lower genital tract.
