BLOOD GLUCOSE TESTING
+ For patients with low risk, blood glucose
testing is not routinely recommended if:
– Member of ethnic group with low prevalence of
GDM
– No known DM in first degree relatives
– Age < 25 years
– Weight normal before pregnancy
– Weight normal at birth
– No history of abnormal glucose metabolism
– No history of poor obstetrical outcome
BLOOD GLUCOSE TESTING
+ For patients with average risk assessment,
they are asked to have blood glucose
evaluated at around 24 – 28 weeks of
pregnancy (if no record of glucose
intolerance beforehand).
+ If the patient is high risk, this should be done
as soon as possible and repeated at 24-28
weeks of pregnancy or any time the patient
shows symptoms of hyperglycemia.
FASTING OR POST PRANDIAL
PLASMA GLUCOSE MONITORING
+ Diet-treated GDM monitored with
glucometers daily are linked in studies of
Hawkins in 2009 to less incidence of
macrosomia in infants as compared to those
having weekly glucose measurements
evaluated at the clinic only.
+ Post Prandial Plasma Glucose monitoring
has been shown to be superior to fasting
plasma glucose monitoring in the study of
Deveciana and colleagues (1995).
GLUCOSE MONITORING
+ Advise pregnant women with diabetes to
monitor fasting blood glucose (in the morning)
and 1 hr after every meal.
+ Women being treated with insulin should
check their blood glucose before sleeping at
night.
+ Additional: DM type 1 patients should be
offered ketone test strips and use them if they
become hyperglycemic or unwell.
ROUTINE LABS
+ CBC (with platelet count)
+ Blood typing
+ UA
+ HBsAg
+ Khan VDRL
+ Pap smear
+ Additional: 24h urinary protein collection, BUN/Crea,
Uric Acid, ALT/AST, LDH, electrolytes, peripheral
blood smear, coagulation profile
RETINAL ASSESSMENT
+ Pregnant women with DM should have retinal
assessment at the first prenatal clinical consult
and 28 wk after if normal. If retinopathy is
found, reassess at 16-20 wk after.
RENAL ASSESSMENT
+ If a pregnant diabetic patient has not had
renal assessment for the past 12 mo, do renal
assessment of serum creatinine or 24 hr.
urine protein at first contact.
+ Refer to a nephrologist if CPK >120 uM/L or
urinary protein >2 g/d.
ULTRASOUND
+ To check for fetal wellbeing
+ Assessing any growth restriction
+ To evaluate amniotic fluid volume
ULTRASOUND
+ Fetal Biometry: crown-lump length, biparietal
diameter, head circumference, abdominal
circumference, femur length; every 10—14 d.
+ Congenital anomaly scan: usually done at 20
wk AOG
+ Biophysical profile: measure fetal tone,
movement, breathing, amniotic fluid volume,
non-stress test; 1-2x/wk.
ULTRASOUND
+ Doppler flow studies: to assess blood flow and
vascular resistance in the uteroplacental &
fetal circulations; at least 1x/wk, 2x/wk if with
complications
ELECTRONIC FETAL HEART RATE
MONITOR
+ NST (as part of the BPP)
+ CST (if with indications for delivery in patients
who are not in labor)
WHEN TO START?
+ Initial testing at 32-34 wk AOG
+ 26-28 wk AOG if particularly worrisome high-
risk conditions
+ Upon diagnosis of medical or fetal
complications
+ PGH: 28 wk AOG
FOLLOW-UP AND ADVICE
Pre-eclampsia
FOLLOW-UP: PREECLAMPSIA
+ Pre-natal exams every 4 weeks during the 1st
and 2nd trimesters
+ 3rd trimester: check-ups minimally at 7-day
intervals (Ideal: Every 3-4 days)
+ If overt HPN (> 140/90 mmHg), proteinuria,
headache, visual disturbance, or epigastric
discomfort develop, admit for 2-3 days to
determine if due to preeclampsia and to
assess severity.
HOSPITALIZATION:
PREECLAMPSIA
The following should be assessed:
+ Admittance weight, and weight everyday thereafter
+ Admittance analysis for proteinuria, and analysis at
least every 2 days thereafter.
+ Sitting BP readings every 4 hours except between
midnight and morning.
+ Plasma or serum creatinine, hematocrit, platelets,
and liver enzymes.
+ Frequent monitoring of fetal size and amniotic fluid
volume.
+ Detailed PE and assessment for headache, visual
disturbances, epigastric pain, and rapid weight gain.
PREECLAMPSIA: COMPLICATIONS
+ Maternal Complications
– HELLP Syndrome (Hemolysis, Elevated Liver Enzymes, Low
Platelet)
– Placental Abruption
– Pulmonary Edema
– Acute Renal Failure
– Eclampsia
– Rarely, cerebral edema, confusion, obtundation, coma
+ Fetal Complications
– Small for gestational age
– Perinatal mortality
ADVICE
+ No need for absolute bed rest and
tranquilizers
+ Sedentary activity for most of the day
+ Home BP, weight and urine protein
monitoring
+ Diet should include adequate protein and
calories
+ Do not limit sodium and fluid intake
+ Instruct mother to monitor and report her
symptoms properly

– Placental Abruption
– Pulmonary Edema
– Acute Renal Failure
– Eclampsia

FOLLOW-UP AND ADVICE
Gestational Diabetes Mellitus
FOLLOW-UP: GESTATIONAL
DIABETES MELLITUS
+ Prenatal Examinations:
– Every 2 weeks until 32 weeks
– Every week thereafter
+ Daily postprandial self blood glucose monitoring
– Fewer macrosomic infants
– Gained less weight
– Fewer cases of neonatal hypoglycemia
– Fewer cases of shoulder dystocia
FOLLOW-UP: GESTATIONAL
DIABETES MELLITUS
+ Postpartum Evaluation:
– Fasting or random plasma glucose 1-3 days after
delivery
– 75-g 2-hr OGTT 6-12 weeks postpartum
– 75-g 2-hr OGTT 1 yr postpartum
– 75-g 2-hr OGTT trianually
– Fasting plasma glucose anually
– 75-g 2-hr OGTT prepregnancy
ADVICE: GESTATIONAL DIABETES
MELLITUS
+ Diet:
– Avoid single large meals and foods rich in
simple carbohydrates.
– Preferred: 6 feedings per day – 3 meals and 3
snacks
+ Proper exercise
– Can improve cardiorespiratory fitness
– Can reduce the need for insulin
