As a departmental protocol, induction for postdate is undertaken at 41 weeks + 3days (40 weeks + 10 days) in uncomplicated pregnancies.
Diagnostic criteria for preeclampsia: hypertension in the second half
of pregnancy (≥20 weeks gestation) with blood pressure ≥140/90 mmHg taken on two occasions at least 6 hours apart in the presence of significant proteinuria (>300 mg of protein in a 24-hour urine collection or ≥2+ of protein on dip stick).
Diagnostic criteria for gestational diabetes: based on fasting blood sugar of ≥7.0 mmol/L (≥126 mg/dL) and 2-hour postprandial of ≥11.1 mmol/L (≥200 mg/dL).
IUGR: Intrauterine growth restriction.
PROM: Premature rupture of membranes.
DM: Diabetes mellitus.
