it would be displaced upward and thus rise in the abdomen


what is the modified Brandt-andrews maneuver?

bringing the fingertips of your abdominal hand straight down above the symphysis into the lower abdomen while holding the umbilical cord taut to check for placental separation (but it is not the same as counterpressure on uterus while pulling on cord/placenta to remove it)

uterine relaxation/atony


what would be indications for postpartum inspection of cervix?

Well-contracted uterus accompanied by steady trickle of blood from the vagina
Presence of anterior lip that had to be pushed back manually
Forceps or vacuum extraction delivery

should be performed with the placeta still attached to the uterine wall
