Comparison of efficacy of intravenous labetalol and intravenous hydralazine for management of pre-eclampsia in pregnant women
Abstract
Objectives: To compare the efficacy of intravenous Labetalol and intravenous Hydralazine in reduction of blood pressure in patients with severe pre-eclampsia.
Methodology: This comparative study was conducted at the Department of Obstetrics and Gynecology at Ziauddin University Hospital, Karachi from1st June 2019 to 30th June 2020. Total 208 pregnant women having severe pre-eclampsia (systolic pressure ≥160 mmHg and diastolic pressure ≥110mmHg) were included in study. Group A received I/V Labetalol. Group B received I/V Hydralazine. Efficacy of drugs was observed by reduction in blood pressure and the number of doses administered. Data was analysed using SPSS version 26.
Results: Systolic blood pressure reduction in Labetalol group was significantly lower than in hydralazine group (105.5 ±11.3 vs. 115.8 ±17.1, p≤ 0.001). Diastolic blood pressure reduction was also lower in labetalol group than in hydralazine group (p= 0.03). Number of dosage of drugs in Group A (Labetalol) was 3.2 ±1.2 vs. Group B (Hydralazine) was 4.4±1.4, p =0.006).
Conclusion: The results of this study show that Labetalol is more effective as compared to Hydralazine in terms of reducing the systolic and diastolic blood pressure and number of doses (Drugs) for in patients with severe preeclampsia.
Keywords: Preeclampsia; bolus dose; Hydralazine; Labetalol.
