Q

Signs of Placenta Previa =

Rationale for bleeding

How do we confirm it? What should you not use!?

A

Painless vaginal bleeding in third trimester

-As the lower uterus begins to contract and dilate in the later weeks of pregnancy the placental villi are torn from the uterine wall, exposing the blood filled uterine sinuses at the placental site-bleeding can be scanty or profuse depending on the number of sinuses involved

Sonographic confirmation, NO VAGINAL SPEC EXAM!

Q

Describe the mechanism of action and the rationale for the medications given in preterm labor

A

Preterm Labor:
Less than 34 weeks: single dose betamethasone to reduce fetal mortality and complications by accelerates fetal lung maturity. Give tocolytic agents to relax the uterus to delay delivery - allow betamethasone to take effect
If less than 32 weeks, then also give a single dose of magnesium sulfate, which has a protective effect on the brain. (Magnesium sulfate is also a type of tocolytic)

Give Rhogam to Rh - mothers to prevent isoimmunization if baby is Rh positive. If mom is exposed to baby’s blood, she will build up antibodies which will attack RH positive babies in future pregnancies.

Q

Describe the underlying mechanisms involved in gestational diabetes

A
  • During the second trimester, maternal hormones (progesterone, hPL, cortisol, and GH) are released, which cause increased glucose in mom’s blood, as well as insulin resistance.
