Background:
Preeclampsia (PreE), a de novo development of Hypertension in consort with proteinuria after 20 weeks of gestation is the leading cause of morbidity and mortality in mother and the offspring. It affects approximately 3-8% of overall pregnancies. Although, specific etiologies remain unknown, it has been supported by various studies that PreE is not just a single disorder, but a syndrome of pertinent multiple pathophysiological factors.
Methods:
An IRB approved retrospective chart review over a year (January 2014 to December 2014) was conducted of all pregnancies occurred at Baylor Scott and White Health System, Temple, Texas (N = 3704). We divided all pregnancies into two separate groups: PreE (N = 299) vs. Non PreE (N = 3405). We compared the neonatal outcomes between two groups including their offspring’s gestational age, birth weight, admission rate to Neonatal Intensive Care Unit (NICU), occurrence of bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), hypoglycemia, thrombocytopenia, intraventricular hemorrhage (IVH) and length of hospital stay (LOS).
Results:
We found amongst these two groups, infants born to PreE mothers have significantly lower birthweight (Mean = 2807 grams, SD = 841 grams) compared to Non PreE mothers (Mean = 3383 grams, SD = 619 grams) (P<0.05), significantly lower GA (Mean = 36.7 weeks, SD = 3.25 weeks) compared to Non PreE group (Mean = 38.7 weeks, SD = 2.1 weeks) (P<0.05), significantly higher rate of BPD (11%) compared to Non PreE group (6.9%)(P<0.05), significantly higher occurrence of hypoglycemia (26%) compared to non PreE group (20%) (P<0.05), significantly higher rate of thrombocytopenia (28%) compared to Non PreE group (17%) (P<0.05) and significantly higher length of hospital stay (Mean = 19 days, SD = 20 days) compared to Non PreE group (Mean = 14 days, SD = 20 days) (P<0.05).
Conclusion:
We can conclude from this retrospective analysis that infants born to PreE mothers have lower birth weight indicating the intrauterine growth restriction and the lower gestational age indicating preterm birth. Moreover, the data indicate the higher rate of BPD, hypoglycemia, thrombocytopenia and requirement of increased length of hospital stay in infants born to PreE mothers compared to Non PreE mothers.
