The goal of study is to verify the hypothesis that increased blood pressure values cause premature delivery. Material and Method: Retrospective Study in which newborn babies of mothers with arterial hypertension were analyzed at I.M.C.C“ Prof. Dr. Alfred Rusescu”, Department of Obstetrics and Gynecology from September1, 2013 to March 1, 2014. Blood Pressure values of pregnant women were analyzed as well as gestational age of the newborns, anthropometric measurements, adaptation to extrauterine life, morbidity and mortality. Results: During the period from September 1, 2013 – March 1, 2014 at the I.M.C.C.”Prof. Dr. Alfred Rusescu, Department of Obstetrics and Gynecology, 1008 births were recorded. Hypertension was present in 4,5% of the cases. Chronic (preexisting) hypertension - 10,41%, gestational hypertension - 75%, Preeclampsia - 12,5% and preeclampsia superimposed upon chronic hypertension -2%. Out of the newborns of mothers with arterial hypertension 29,1%had a GA<37 weeks,and 60% of these came from mothers with arterial hypertension (AHT) values for systolic AHT>160mmHg and diastolic AHT>110mmHg. Perinatal asphyxia was present in 64,28% of the premature babies, 28,57% required invasive resuscitation techniques. Complications stemming from severe AHT in the mother include cardiorespiratory, digestive, metabolic and cerebral. Two intrauterine deaths were recorded in mothers with gestational hypertension, where values reached 200/140mmHg and 180/100mmHg. Conclusion: Severe Hypertension (systolic AHT>160mmHg, diastolic AHT>110 mmHG) and Preeclampsia superimposed on Chronic Hypertension represents the highest risk for “iatrogenic” preterm delivery.
