Evaluation of intravenous infusion of labetalol versus magnesium sulfate on cerebral hemodynamics of preeclampsia patients with severe features using transcranial doppler.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

It is essential to understand the underlying pathophysiological mechanisms of preeclampsia cerebral complications.

This study aimed to compare the cerebral hemodynamic effects of magnesium sulfate (MgSO4) and labetalol in pre-eclampsia patients with severe features.

Why It Was Studied

The institutional review board of the Faculty of Medicine, Zagazig University approved this study with the reference number (ZU-IRB#: 6353-23-3-2020) and it was registered at clinicaltrials.gov (NCT04539379).

Who Took Part

PubMed tags the participants as women only.

Singleton pregnant women who suffered from late onset preeclampsia with severe features were enrolled and subjected to baseline Transcranial doppler (TCD) evaluation and then randomly assigned to either the magnesium sulfate group or labetalol group.

TCD to measure middle cerebral artery (MCA) blood flow indices including mean flow velocity (cm/s), mean end-diastolic velocity (DIAS), and pulsatility index (PI) and to estimate CPP and MCA velocity were performed as basal measurements before study drug administration and at post-treatment one and six hours after administration.

How the Study Was Run

The researchers set it up as a randomized study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

The occurrence of seizures and any adverse effects were recorded for each group.

What Was Measured

The subject headings attached to it are Pre-Eclampsia, Magnesium Sulfate, Labetalol, Hemodynamics, Ultrasonography, Doppler, Transcranial, Blood Flow Velocity and Cerebrovascular Circulation.

Author keywords: Cerebral hemodynamics and Severe preeclampsia.
