More common with direct abdominal<unk>  in second half of<unk> 
Occurs in severe MVAs resulting in pelvic fractures, penetrating<unk> 
Signs and Sx
maternal shock
abdominal distension
abnormal uterine contour
abnormal fetal lie (oblique or transverse)

Placental Abruption
Most common cause of fetal demise in blunt<unk> 
US alone not sensitive → do not delay treatment for ultrasound if abruption suspected
Signs and Sx
abdominal pain
uterine tenderness
vaginal bleeding (70%, may be absent if retroplacental)
uterine contractions or hypertonicity
signs of fetal distress on toco monitor are often the earliest indicator
decelerations, tachycardia, bradycardia, and loss of variability
