Feto-maternal outcomes of hypertensive disorders of pregnancy in Yekatit-12 Teaching Hospital, Addis Ababa: a retrospective study.

BACKGROUND

In resource poor countries, hypertensive disorders of pregnancy are common and form one of the deadly triads, along with hemorrhage and infection, which contribute greatly to maternal and fetal jeopardy.

METHODS

The aim of this study was to assess the prevalence of hypertensive disorders of pregnancy, and determine the effects of hypertensive disorders of pregnancy on the feto-maternal outcomes. It was a descriptive, cross-sectional, retrospective study on randomly selected 615 women who attended delivery at Yekatit-12 Teaching Hospital from 1st of July 2017 -1st of Jan 2018. Data was analyzed using SPSS version 20 software. Descriptive statistics were used to calculate rates. Chi-square statistics were used to estimate the associations among selected predictor variables. A p-value < 0.05 was taken as statistically significant.

RESULTS

Out of the 615 study population, the prevalence of hypertensive disorders of pregnancy was found to be 25.4%, of which the majority (52.5%) was severe pre-eclampsia. Eclampsia accounted for 2.6%, and superimposed pre-eclampsia was 2.6%. The rate of severe pre-eclampsia with HELLP syndrome was 7.1% of all mothers with the hypertensive disorders. The majority of mothers with hypertensive disorders (59.6%) had age range of 25-34 years. About 46% of mothers required interventions to terminate the pregnancy either by cesarean section (42.3%) or instrumental deliveries (3.7%) due to conditions related to Hypertensive disorders. The rate of preterm, low birth weight, and low Apgar at 1st and 5minutes accounted for 29.5, 24.4, 22.4 and 16.7% of neonates born to mothers with hypertensive disorders, respectively. Over 10.9% of neonates required resuscitation and 11.5% NICU referral. The rate of still birth was 3.8%.

CONCLUSION

The prevalence of hypertensive disorders of pregnancy is high in the study area and complicates maternal and fetal outcomes of the pregnancy. To deter its detrimental effects both on fetal and maternal outcomes of pregnancy, antenatal surveillance should be expanded to enable early detection, stringent follow-up and timely intervention in severely affected pregnancies.
