NAVA Versus BiPAP Non-Invasive Respiratory Support in Infants Following Congenital Heart Surgery (NAVA)

March 2, 2020 updated by: Children's Hospitals and Clinics of Minnesota

Neurally Adjusted Ventilatory Assist (NAVA) Versus Conventional Biphasic Positive End Expiratory Pressure (BiPAP) Non-Invasive Respiratory Support in Infants Following Congenital Heart Surgery

Pediatric patients often require prolonged mechanical ventilation after cardiac surgery which comes with many undesirable effects. As a result, neurally-adjusted ventilatory assist (NAVA) and biphasic positive airway pressure support (BiPAP) have been developed as non-invasive alternatives to providing respiratory support post-operatively. The investigators hypothesize that providing synchronized biphasic support with NAVA will be associated with shorter duration of non-invasive respiratory support, less sedation requirements, and reduced length of hospital stay. This is a prospective, randomized study. Subjects are randomized to receive either NAVA or BiPAP following their cardiothoracic surgery.

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

Mechanical ventilation is often very necessary in the care of critically ill pediatric patients. However, it comes with many different complications that include chronic lung disease, tissue damage, and ventilator-associated pneumonia. Over time, we have increased our understanding of how a child's physiology interacts with a ventilator and this has led to two different non-invasive forms of respiratory support: bilevel positive air pressure (BiPAP) and neurally adjusted ventilator assist (NAVA). While both modalities come with a lot of benefits such as improved gas exchange, decreased respiratory and heart rate and decreased inspiratory work of breathing, NAVA has the ability to provide synchronous ventilatory support due to the electrical activity of the diaphragm.

The purpose of this study is to compare clinical outcomes following use of NAVA versus BiPAP in patients undergoing cardiac surgery, Specifically, comparisons of non-invasive respiratory support, duration of sedation, and length of hospital stay. The investigators hypothesize that the use of NAVA will lead to a shorter duration of non-invasive respiratory support, less sedation requirements, and reduced length of hospital stay compared to the use of BiPAP.

This is a single-site, prospective randomized study. Subjects are randomized into two arms: those who receive NAVA and those who receive BiPAP post-operatively.

Subjects will be followed for up to 14 days post-operatively or until they are discharged, whichever comes first. Pain medication administered, FLACC (Face, Legs, Activity, Cry, Consolability), and SBS (State Behavioral Scale) scores are recorded daily for up to 14 days.

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.

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: Neurally-Adjusted Ventilatory Assist (NAVA)
Synchronized biphasic non-invasive respiratory support
Device: Neurally-Adusted Ventilatory Assist (NAVA)
Delivery of positive pressure is based on the electrical activity of the diaphragm (Edi) via a nasogastric (NG) catheter that is placed on the phrenic nerve, which runs along the esophagus. This results in synchronous ventilation for the patient.
ACTIVE_COMPARATOR: Biphasic Positive Airway Pressure Support (BiPAP)
Conventional non-invasive respiratory support
Device: Biphasic Positive Airway Pressure Support (BiPAP)
Conventional form of non-invasive respiratory support that does not deliver positive airway pressure in a synchronous fashion.
