Milrinone Inhaled in Cardiac Surgery

October 23, 2013 updated by: Andre Denault

2- Inhaled Milrinone Prevents the Increase in Pulmonary Artery Pressure After CPB

Pulmonary hypertension is an important morbidity factor in patients having to undergo cardiac surgery with cardiopulmonary bypass (ECC). Milrinone used in inhalation, shows evidence of being a pulmonary vasodilator able to possibly contribute to the reduction of pressure on the pulmonary artery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

This controlled, randomized, double-blind study will aim at confirming the efficiency as well as the security of Milrinone, used in inhalation, to diminish the degree of pulmonary hypertension before the cardiopulmonary bypass (ECC) circulation. In addition, the pharmacokinetic and echo graphic repercussions of administering the medication will be analysed. At the present time, there is no data on the pharmacokinetics of the medication when it's administered through inhalation. For this reason, we would like to study the serous rate of the medication in the minutes following its administration through inhalation.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 90 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Adult patients scheduled for elective valvular or complex (2 or more valves or
  • valve and revascularization) cardiac surgery under CPB with preoperative PHT defined as mean pulmonary artery pressure (MPAP) over 30 mmHg or
  • systolic pulmonary artery pressure (SPAP) over 40 mmHg (using preoperative right-sided catheterization or estimated by echocardiography).

Exclusion Criteria:

  • Cardiac surgery not requiring CPB, contraindication to TEE (esophageal pathology or unstable cervical spine) and emergency surgery.
  • Patients will be recruited the day before surgery and randomized using computerized cards by the pharmacy department

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
To demonstrate that inhaled milrinone administered before CPB is superior to placebo in reducing the severity of difficult separation from bypass
Time Frame: End of CPB
End of CPB

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.
Outcome Measure
Time Frame
Reduction in morbidity and mortality post-op
Time Frame: At discharge, 3 months, 6 months and 1 year by telephone
At discharge, 3 months, 6 months and 1 year by telephone
