What was the concern of diazepam/ bentos in a past retrospective study on teratogenesis
What is the concern about using nitrous oxide in obstetric patients.
It inhibits methionine synthase activity involved in DNA synth
does nitrous oxide decrease uterine tone
do anesthetic gases decrease uterine tone
does epidural medication provide uterine relaxation
a pt w/ retained placenta. Bp and hr stable…what can help to give uterine relaxation.
intravenous nitrous 50-100mcg

what happens to intestinal motility during pregnancy
what happens to LES during pregnancy
