30-50%

19
Q

what bad syndrome can the prego get from aspiration? and what are it’s characteristics?

High gastric volume

is chemical pneumonitis caused by aspiration during anaesthesia, especially during pregnancy.

are the prego’s hypercoagable

yes

28
Q

Stages!!

what are the stages of ppregnancy

b/c we want the mom to push (we want her to participate in birth)
epidural allows participation
spinal doesn’t allow participation
