|
|
|
Term
|
Definition

- viability of fetus depends on extent of rupture and EBL
Woman can't conceive after rupture UNLESS it was in inactive lower segment |
|
|
Term
|
Definition
- uterus turns inside out with birth of of fetus or delivery of placenta
- Cx:
- traction applied to umbilical cord to remove placenta
- pressure to fundus so fetus pulls fundus down at birth
- can be totally inverted and protrude from vag or just lie in uterine cavity
- large amount of blood from vagina in sudden gush
- Sx of bloood loss (hypotension, pale, dizzy, sweat)
- NEVER try and replace uterus, it just causes more blood loss
