diabetes in pregnancy Flashcards
(27 cards)
type 1 diabetes mellitus
- absolute insulin deficiency- typical onset
type 2 diabetes mellitus
- insulin resistance- decreased insulin production- onset > 30y, may occur before- strong association with obesity
gestational diabetes mellitus
diabetes first identified in pregnancy, typically resolves following birth (patient at risk for type 2 after)may be due to reduced (maternal) tissue sensitivity to action of insulinrepresents 90% of diabetes in pregnancy cases

antepartum gdm screening
risk assessment for ALL women at first visitscreen ALL women 24-28 weeks
antepartum gdm screening: fasting blood sugar value
> 126 = gdm
antepartum gdm screening: random blood sugar
> 200 = gdm
antepartum gdm screening: 1 hour gtt (how & what)
chug glucose; 1 hour after finishing, test.> 140 = move to 3 hour> 175 = go straight to endocrinologist
antepartum gdm screening: 3 hour gtt (how & what)
takes 4 hours and fasting!- draw blood, chug glucose- draw blood @ 1, 2, 3 hours after
fetal kick counts (when & what)
@ 24 weeks, daily through delivery
fetal echocardiogram (when & what)
initial HbA1c elevated20-22 weeks?
bpp (when & what) type i dm
32 weeks through delivery
bpp (when & what) type ii dm
40 weeks through delivery
bpp (when & what) iugr, preeclampsia
26 - 28 weeks through delivery
non-stress test
biweekly?
contraction stress test
if bpp not available?
polycythemia
Increased number of erythrocytes per volume of blood- may be caused by large placental, fetus, or maternal-fetal transfusion- may be attributable to hypovolemia resulting from movement of fluid out of vascular into interstitial compartment
glucose levels to maintain during labor+ how often+ when to ketone
80 - 120 mg/dl plasma70 - 110 mg/dl whole blood (capillary)assess glucose q 1-2 hours (q 2-4 hours for gdm)assess ketones periodically and for glucose > 200 mg/dl
hyperglycemia s/s
- increased appetite, thirst (unusual)- loss of weight, strength, stamina- leg cramps, muscle fatigue- nausea, vomiting
hypoglycemia s/s
- increased appetite- sweating- loc, irritability, headache- palpitations- weakness, lethargy
hypoglycemic episode IV response
discontinue IV insulin (glucose
