so i had this 16 week pregnant restrained lady driver involved ina soft mvc, was rearended at a stop sign, slow speed. no injuries sustained. went home, started to have some lower abd cramping. NO vag bleeding. what my attd and i wanted to do was a quick bedside u/s check urine and then send home...but what had crossed my mind was checking an rh and getting a formal u/s (i dont know about most of you but i dont know how to identify sub chorionic hemmorrage or placental hematoma, etc), mainly b/c if there is a hx of trauma, and pt is rh neg, don't we need to rule these things out? or are there some of you that routinely give rhogam to rh neg women without vaginal bleeding but with a hx of trauma?
