HVNI for Successful Weaning in Respiratory Failure (REVIVER)

May 9, 2023 updated by: Ahmed Salama Sadaka, Alexandria University

RolE of High Velocity Nasal Insufflation in imrpoVing wEaning Success in Respiratory Failure Patients (REVIVER)

The goal of this randomized active-controlled study is to investigate the role of high velocity nasal insufflation (HVNI) in the immediate post-extubation period and compare it with non-invasive positive pressure ventilation (NIPPV) as regards to weaning success rate. The study will recruit those who have been on invasive mechanical ventilation for at least 3 days and with a high risk of weaning failure.

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 is a single center prospective randomized controlled open label trial of high velocity nasal insufflation (HVNI) in the immediate post-extubation period versus noninvasive positive pressure ventilation (NIPPV). After at least 72 hours from intubation, for respiratoy failure, those who are considered to be eligible for weaning from mechanical ventilation based on the weaning protocol but are at high risk for extubation failure will be randomized to either HVNI or NIPPV. Data on the respiratory and cardiovascular status will be continuously monitored and recorded thereafter.

The primary outcome measure will be failure of either arm within 72 hours of initiation, leading to reintubation (or crossover only from a failed HVNI allocation to NIV based on clinical judgement to avoid reintubation in selected cases). Secondary outcomes to be investigated include: 1) Failure of HVNI or NIPPV after 72 hours from initiation, 2) hospital mortality, 3) length of ICU stay, 4) length of hospital stay, 5) incidence of ventilator associated pneumonia, 6) patient tolerance and comfort, and 7) ICU readmission or mortality at 28-days post hospital discharge.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: High Velocity Nasal Insufflation (HVNI)

HVNI (Precision Flow; Vapotherm®, Inc, Exeter, NH) will be delivered using a small-bore nasal cannula initiated at a flow rate set to 35 L/min, temperature of 35-37°C and FiO2 at 1.0. Adjustments in flow (up to 40 L/min) and temperature will be titrated to optimize patient's comfort.

The target parameters after initiation will be as follows:

  1. RR< 25 bpm
  2. HR< 120 bpm
  3. SpO2 92-94%
Device: High Velocity Nasal Insufflation
A relatively new respiratory support modality which delivers very high velocity flows. This improves ventilatory efficiency via washing out carbon dioxide occupying the anatomical dead space of the upper airways.
Other Names:
  • HVNI
Active Comparator: Non-invasive positive pressure ventilation (NIPPV)

NIPPV will be initiated with an oronasal mask, with inspiratory and expiratory positive airway pressures (IPAP, EPAP) set at IPAP 10-20 cm H2O and EPAP 5-7 cm H2O to be titrated according to patient's response and comfort. FiO2 will be initiated at 1.0 for noninvasive positive-pressure ventilation.

The target parameters after initiation will be as follows:

  1. RR< 25 bpm
  2. HR< 120 bpm
  3. SpO2 92-94%
Device: Non-invasive positive pressure ventilation
An established non-invasive ventilation method via delivery of an expiratory positive airway pressure and inspiratory positive airway pressure.
Other Names:
  • NIPPV
