Identify maternal and perinatal outcome of vaginal parturition in pregnant women with Chronic Arterial Hypertension (CAH).A transversal and retrospective study was performed involving all pregnant women who were attended at Hospital Guilherme Álvaro’s Prenatal Service for Women with Hypertension or Nephropathies in Santos–SP/Brazil in the period (January 2012–December 2013) and that had obstetric resolution by vaginal delivery, totaling 31 pregnant women. A descriptive and exploratory analysis of the collected data through frequency tables and graphics was performed.The most frequent expression of CAH found was the mild form (diastolic arterial blood pressure 90–100mmHg) with a 93.55% share of all cases studied.VariableResultVariableResultMaternal ageAverage of 33.29 years oldUterine atony on the puerperiumTwo patients (6.45%)Number of gestationsAverage of 3.84Average duration of maternal hospitalization5.45 daysNumber of paritiesAverage of 2.19Prematurity16.13%Interrelation with co-morbiditiesObesity (41.94%) and diabetic (35.48%)Weight of newborn⩾2500g87.10%Association with preeclampsia38.71%Apgar score at 5min ⩾ 793.55%Most used diagnosis method of PEProteinuria/24-h (58.33%)Meconium amniotic fluid at deliveryNoneAdministration of magnesium sulfate and hypotensorOne patientPerinatal complicationsIsolated birth injury (46.67%) Birth injury and respiratory distress (26.67%) Isolated respiratory distress (20%) and neonatal anoxia (6.66%)Most used method for the inductionMisoprostol followed by Oxytocin (52.17%)Admission in neonatal Intensive Care Unit03 newborns (9.68%)Admission in Intensive maternal Care UnitOne patient (3.23%)Neonatal deathOne (3.23%)Maternal intercurrences are not related to via of delivery and perinatal complications when present did not correlate with the CAH. Despite the small sample on the study, there were no maternal and perinatal adverse outcomes that contraindicate vaginal delivery in patients with Chronic Arterial Hypertension.M. David: None.
