September 30, 2024 updated by: Leila Katz, Instituto Materno Infantil Prof. Fernando Figueira

Effectiveness of Postpartum Furosemide on Recovery Blood Pressure in Puerperal Women with Severe Preeclampsia: a Randomized Clinical Trial

The purpose of this study is to determine if furosemide administered after the first 24 hours of delivery, in women with severe peeclampsia and eclampsia accelerates high blood pressure control and diminishes hospital stay.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A placebo-controlled study that will be conducted including 120 postpartum women with severe preeclampsia . Women who are previosuly diuretic users, with renal impairment, hemodynamic instability or with contraindications to diuretic use will be excluded. Informed consent will be obtained from all participants . Patients will be randomized to receive furosemide ( 40mg orally every twenty-four hours ) or placebo for maximum of five days. The variables are systolic and diastolic blood pressure, frequency of very high blood pressure, need for maintenance of antihypertensive therapy , number of antihypertensive agents used to control blood pressure , urine output , length of hospital stay , adverse effects and maternal complications . Except for the study drug, patients will receive all care and monitoring according to the hospital protocol and decision to initiate or modify antihypertensive therapy will be defined by the attending physician, as well as the decision to discharge. If the patient is discharged before five days of the protocol drug, this drug will be stopped. Teh patients may decide to leave the study at any moment. Data will be collected by researches daily. Plan statistical analysis will be performed using the public domain program Epi Info 7.0 and the mean and dispersion measures for numerical variables will be calculated. To compare means obtained every day and between groups will be used analysis of variance ( ANOVA ) . Nominal variables were compared using the X2 test or Fisher if necessary. Be considered significant at p < 0,05. The risk ratio (RR) is calculated as a measure of the relative risk for the different outcomes , according to furosemide or placebo

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Mean blood pressure
Time Frame: from 24 hours after delivery to first 15 days of delivery
from 24 hours after delivery to first 15 days of delivery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
