- Abstract
Background: Hydralazine, labetalol, and nifedipine are the recommended first-line treatments for severe hypertension in pregnancy. While all three are effective, there is a lack of sufficient evidence regarding their comparative safety and efficacy., Objective: To determine the comparative safety and efficacy of the first-line treatment options for severe hypertension in pregnancy., Methods: A systematic search of Medline, Embase, and Cochrane Central Register of Controlled Trials up to May 31, 2018 was conducted. RCTs in pregnancy comparing a first-line antihypertensive agent to another first-line agent for the treatment of severe hypertension in pregnancy. Screening, data abstraction, and quality assessment were done by two independent reviewers. To estimate relative effects from all available evidence, a Bayesian network meta-analysis with vague priors was conducted., Main Results: Of the 1330 publications identified, 17 RCTs comprised of a total of 1591 women met our selection criteria. For successful treatment of severe hypertension, nifedipine was found to be superior to hydralazine (OR 4.13 [95% CrI 1.01-20.75]) but not labetalol (OR 3.43 [95% CrI 0.94-19.95]). This was not associated with an increased risk for caesarean delivery or maternal side effects. There was no significant difference between labetalol and hydralazine., Conclusions: Given the results of this systematic review and network meta-analysis, maternity care providers should feel comfortable initiating management of severe hypertension in pregnancy using oral nifedipine., (Copyright © 2019 International Society for the Study of Hypertension in Pregnancy.
