Pathophysiology
- release of amn fluid to maternal vessels during intense ut contractions or manipulation or at areas of placental separation.
- most common during labor
- leading cause of death during induced abortions
- can also be spontaneous or blunt trauma with abruption
- also post amniocentesis
Diagnosis
- 2 or 3 trimester
- ut contraction or manipulation
- sudden hypotension, hypoxia, or coagulopathy
- triggers immunological response
- death by vasospasm, release of vasoactive substances, mechanical plugging of mat pulm vasc tree
- get ARDS and L vent dysfnctn
- fetal hair, squamous epithelial cells and debris in mat circulation
