More than 500cc blood loss within the first 24 hours after normal vaginal delivery, or more than 1000cc after cesarean section.
Incidence of 2-5%, with a recurrence rate of 20-25%.
Four T's: tone, tissue, trauma, thrombin
Tone: anything that predisposes to uterine atony
Tissue: preventing contractions
Trauma
Thrombin: coagulopathy
PPH can be prevented by actively managing the third stage through giving oxytocin 5u IM or IV as the anterior shoulder delivers. This reduces risk of hemorrhage as well as retained placenta.
ABC's
talk to and observe patient
start at least one large bore IV and run saline drip wide open
give oxygen
CBC, type and X-match
consider coagulation studies
Ensure good analgesia, good lighting, and good exposure
If the placenta is undelivered, remove manually, along with any potential clots.
Massage the uterus and explore for retained tissue, uterine inversion or rupture
inspect the perineum, vagina, and cervix for lacerations
catheterize the bladder
Give IV oxytocin 20-50 units/litre; run wide open in saline or Ringer's
ergot
hemobate
misoprostol
Reinspect, including previous surgical repair of lacs
Evaluate for acquired coagulopathy
If uterus remains atonic, prepare for OR
