Occurs in 5-8% of deliveries
Postpartum hemorrhage causes ?
Uterine atony
Obstetric lacerations
Retained placental tissue
Coagulation defects
Postpartum hemorrhage Tx.: redelivery ?
type and cross match
Postpartum hemorrhage Tx. after delivery ?
gentle uterine massage. If excessive, may interfere instead of aid
Postpartum hemorrhage Tx. placenta ?
Usually separates and is delivered 5-15 mins after baby
Do not attempt to speed this up
Gentle traction on umbilical cord
check and make sure both sides are smooth and intact
____________ is the 3rd leading cause of maternal mortality in US
Hemorrhage
Most common cause of PP hemorrhage (50%) ?
Uterine atony
Uterine atony patho ?
Myometrium cannot contract
Uterine atony causes ?
Excessive manipulation of the uterus
General anesthesia
Overdistention of the uterus # gestations, etc
Prolonged labor
Fibroids
Uterine infection
Operative delivery
Uterine atony Tx ?
Uterotonic agents (oxytocin) as soon as the infant’s anterior shoulder is delivered
Bimanual uterine massage
Oral misoprostol (prostaglandin)
Obstetric lacerations causes ?
Episiotomy
Lacerations (tears) of uterus, cervix, vagina, vulva
Quick or uncontrolled delivery
Large infant
**if the keep bleeding , look for hematoma collections and they you will find the source of bleeding **
Obstetric lacerations Tx. ?
Inspect the vagina and cervix
Repair episiotomy after massage has produced a firm, contracted uterus
If hematoma is identified, open and evacuate
**if U us contracted and you still see bright red blood? think this **
Retained placental tissue occurs in ?
placenta accreta
**Accreta – implantation is too deep, the dicidua layer is missing and now there is no separation of the placenta **
Retained placental tissue: _____ of cases of PP hemorrhage
5-10%
Retained placental tissue increased frequency b/c of ?
multiple c-sections
Retained placental tissue Dx by ?
transvaginal sono
Placenta accreta ?
A decidual layer normally separates the placenta villi and the myometrium. When there is no decidua, it is termed placenta accreta vera.
**if it does not peel off it just never stopped bleeding and this leads to hysterectomy **
Placenta increta ?
villi invade the myometrium
inside the wall
Placenta percreta ?
villi penetrate the myometrium
through all layers of U
Most common type of placental adherence anomaly ?
Placenta accreta
Major cause of peripartum hysterectomy ?
Placenta accreta
Placenta accreta etiology ?
UKN
Placenta accreta increased with ?
Placenta previa
Previous uterine incision
Multiparity
Previous D&C
Placenta accreta dx w/ ?
Can be diagnosed prior to delivery – esp Color Doppler imaging
Placenta accreta pathophysiology ?
retained placental parts prevent myometrium from contracting, hemostasis cannot be achieved
Not a problem during pregnancy or delivery
Explore placenta – parts missing
Placenta accreta: Tx if minimal bleeding ?
conservative tx –
pelvic artery embolization, then
IM methotrexate.
Placenta may eventually slough
Placenta Accreta: Possibly retains ________, recurrence is high
fertility
Placenta Accreta Tx If placenta is totally adherent, ?
manual removal cannot be done
