therapy for control of blood pressure in preeclampsia

INTRODUCTION
Hypertensive disorders of pregnancy are common cause
of maternal and fetal morbidity and mortality.
1
Severity
of it ranges from mild form of hypertension to multi
organ failure and even death. It affects approximately 5-
10% of pregnancies and responsible for 14% of maternal
death worldwide.
2
Hypertension during pregnancy includes gestational
hypertension, preeclampsia, eclampsia, chronic
hypertension, and preeclampsia superimposed on chronic
hypertension.
3
Among this preeclampsia either alone or
superimposed on chronic hypertension and eclampsia are
majorly responsible for complications.
4
Preeclampsia is
defined as onset of hypertension (systolic blood pressure
more than 140 mmHg and/or diastolic blood pressure
more than 90) in previously normotensive woman along
with proteinuria (>300 mg/24 hours) with or without
signs of end organ damage after 20 weeks of gestation.
5
Women with preeclampsia have increased risk of
developing renal failure, Liver impairment, disseminated
intravascular coagulopathy, cardiovascular diseases,
cerebral hemorrhage, abruptio placenta, IUGR, and pre
term delivery.

Early diagnosis of preeclampsia, regular
antenatal check-up, appropriate management of
hypertension and early intervention by delivery can
significantly reduce these complications.
Effective control of hypertension is one of the important
steps in the management of preeclampsia and if blood
ABSTRACT
Background: Worldwide hypertension during pregnancy is a common cause of maternal and fetal morbidity and
mortality. Effective control of blood pressure is one of the important steps in management of preeclampsia. Few drugs
like nifedipine, labetalol, methyldopa, and hydralazine have acceptable high safety profile during pregnancy.
Methods: In this study 120 antenatal women with non-severe preeclampsia were compared by giving either
nifedipine or labetalol as a single drug therapy for control of blood pressure. Various parameters like control of blood
pressure, side effects of drugs, gestational age at the time of delivery, mode of delivery, any complication and
perinatal outcome were assessed.
Results: In this study authors found that in both group, adequate control of blood pressure was achieved. This study
shows slightly higher rate of pre term delivery and LSCS with labetalol and minimal side effects with nifedipine but
difference in each group is insignificant.
Conclusions: Labetalol and nifedipine both the drugs are equally effective in reducing blood pressure and any of it
can safely be used as a first choice of drug for management of hypertension in preeclampsia and it can be decided as
per clinician’s experience and familiarity with drug.
