high risk pregnancy Flashcards
what do we expect blood sugars to look like in early vs later in pregnancy?
early: low
later: hyperglycemia and resistance to insulin
normal 1 hr GTT results (50gm oral glucose)
135-140 mg/dL
3 hr GTT (100gm oral glucose)
1 hr: > 180 mg/dL
2 hr: > 155 mg/dL
3 hr: 140 mg/dL
how is gestational diabetes diagnosed?
1 hr GTT –> 3 hr GTT –> 2 values must meet or exceed the value = diagnosis
maternal implications od diabetes
- ketoacidosis
- vascular disease
- nephropathy
- retinopathy
- hydramnios
- HTN
- dystocia
fetal implications of diabetes
- higher risk for fetal death
- congenital anomalies
- LGA
- IUGR
- RDS
- hyperbilirubinemia
- hypocalcemia
what are the insulin requirements early in pregnancy?
insulin needs typically decrease
what are the insulin requirements later in pregnancy?
insulin needs greatly increase
what are the insulin requirements postpartum?
insulin needs decrease
insufficient hemoglobin production
r/t nutritional deficiency
ex: iron deficiency, folate deficiency
hemoglobin destruction
r/t inherited disorders
ex: sickle cell anemia
possible maternal complications in iron deficiency anemia
- infections
- fatigue bc they have less ability to carry O2
- preeclampsia
- tolerate blood loss poorly
possible fetal complications in iron deficiency anemia
- low birth weight
- preterm delivery
- fetal demise
- neonatal death
prevention of iron deficiency anemia in pregnancy
- prenatal vitamins
- 60-120 mg of iron/day
- iron rich diet
possible fetal complication of megaloblastic anemia (folate deficiency)
neural tube defects
prevention of megaloblastic anemia (folate deficiency)
- 0.4 mg folate/day
- 1 mg folate + iron supplement
possible fetal complications of sickle cell anemia
- fetal death
- prematurity
- IUGR
pre-existing heart disease (repaired or not) is associated with…
cyanosis = greater maternal/fetal risk
peripartum cardiomyopathy
- no previous hx of heart disease prior to pregnancy
- left ventricle dysfunction
- occurs during second half of pregnancy
