What to do in the case of PPH due to uterine atony:
Bimanual uterine massage, IVF, O2. Oxytocin is first line uterotonic med. If oxytocin fails, give methylergonovine (causes SM constriction, uterine contraction, and vasoconstriction). Carboprost can also be used (synthetic prostaglandin that stimulates uterine contraction) but this causes bronchoconstriction so avoid in asthma patients.

Luteoma (benign ovarian tumor). Could also be theca lutein cysts but this has lower likelihood of female virilization.
How does management of preterm labor differ if mom is < 32 weeks gestation vs <34 weeks?
Rx for preterm labor at < 34 weeks includes tocolytics (indomethacin, nifedipine) to postpone delivery and corticosteroids (betamethasone) to decrease risk of Neonatal RSD. Should also give Mg Sulfate at <32 wks for neuroprotection.
** Don’t give nifedipine and Mg Sulfate together because this will cause respiratory depression.
HRT, age at first live birth, nulliparity, and alcohol consumption should all be considered modifiable risk factors for:
breast cancer.
