Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study proposes a randomized controlled trial of the use of glucocorticoids to improve the clinical course of neonates post-cardiopulmonary bypass (CPB). The study will focus on neonates for a few reasons. Although their post-CPB clinical course is typically more severe and intensive care unit (ICU) care more prolonged than older children, their modes of morbidity are also well characterized. Further, the high level of severity itself provides a substrate for identifying the positive effects of a particular therapy. Finally, a therapy identified as beneficial has the greatest potential for benefit in this vulnerable population. The well characterized scenario of low cardiac output syndrome (LCOS) will be used as the primary endpoint, while a variety of secondary endpoints will be related to the biochemical anti-inflammatory effects of therapy, ICU care and late neurological outcome.

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

No older than 4 weeks (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  • Neonates Age </= 1 month
  • Scheduled to undergo cardiac surgery involving Cardiopulmonary Bypass (CPB) (reparative or palliative procedures)
  • Inpatient Status at MUSC a minimum of 8 hours prior to planned surgery

Exclusion Criteria:

  • Prematurity: </= 36 weeks post gestational age at time of surgery
  • Treatment with steroids, other than inhaled forms, in the two weeks prior to scheduled surgery
  • Participation in research studies involving the evaluation of investigational drugs within 30 days of randomization

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Single dose steroid
Neonates with congenital heart disease requiring surgery utilizing a cardiopulmonary bypass (CPB) machine in the first month of life that receive ONE dose intravenous methylprednisolone (IVMP) prior to heart surgery.
Drug: methylprednisolone (IVMP)
Neonates with congenital heart disease requiring surgery utilizing a cardiopulmonary bypass (CPB)machine in the first month of life that receive ONE doses intravenous methylprednisolone (IVMP) prior to heart surgery.Compare the effects and preoperative and intraoperative IVMP (2 dose steroid)to intraoperative IVMP alone (single dose steroid) on the inflammatory response to CPB cardiopulmonary bypass.
Other Names:
  • Solumedrol
  • Steroid
  • glucocorticoid
Experimental: Two Dose steroid
Neonates with congenital heart disease requiring surgery utilizing a cardiopulmonary bypass (CPB) machine in the first month of life that receive TWO doses intravenous methylprednisolone (IVMP) prior to heart surgery.Compare the effects and preoperative and intraoperative IVMP to intraoperative IVMP alone on the inflammatory response to CPB cardiopulmonary bypass. The hypothesis is that neonates treated with preoperative IVMP as well as the standard intraoperative IVMP will have decreased production of pro-inflammatory cytokines.
Drug: methylprednisolone (two doses IVMP)
Neonates with congenital heart disease requiring surgery utilizing a cardiopulmonary bypass (CPB)machine in the first month of life that receive TWO doses intravenous methylprednisolone (IVMP) prior to heart surgery.Compare the effects and preoperative and intraoperative IVMP to intraoperative IVMP alone on the inflammatory response to CPB cardiopulmonary bypass.

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
Measure Description
Time Frame
Primary Endpoint: Number of Participants With Low Cardiac Output Syndrome (LCOS) or Death at 36 Hours From Admission to the Intensive Care Unit (ICU) After Surgery.
Time Frame: 36 hours
The presence of low cardiac output syndrome (LCOS) was defined by the same definition used in the PRIMACORP study (Hoffman TM.et.al. Circulation 2003 107:996-1002). Specifically, if there were clinical signs and symptoms of low cardiac output (e.g., tachycardia, oliguria, cold extremities, cardiac arrest, etc.) which required one or more of the following interventions: mechanical circulatory support, the escalation of existing pharmacological circulatory support to >100% over baseline, or the initiation of new pharmacological circulatory support.
36 hours

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
Measure Description
Time Frame
Inotropic Score
Time Frame: over the first 36 hours after surgery
The inotropic score was calculated by the equation using drug dosages in micrograms/kg/min, (dopamine+dobutamine) + (milrinonex10) + (epinephrinex100) and recorded hourly upon arrival to the ICUthrough 36 hours postoperatively. The highest score during this timeframe was recorded. This score converts dosages of commonly used inotropic medications into a score. The higher the score the more inotropic medications required. The minimum score would be zero indicating no inotropic medications were used. There is no maximum score.
over the first 36 hours after surgery
Number of Participants Who Died Between 36 Hours and 30 Days Following Cardiac Surgery
Time Frame: at 36 hours and 30 days
Number of participants who died of any cause between 36 hours and 30 days following cardiac surgery
at 36 hours and 30 days
Urine Output
Time Frame: over 36 hours
Total urine output in mL over the first 36 hours after cardiac surgery
over 36 hours
Total Intake/Output of Fluid
Time Frame: over 36 hours
Total amount of all fluids in and out during the first 36 hours postoperatively in mL.
over 36 hours
