Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, randomized, unblinded trial of trauma patients in the ICU who are identified as being at a high risk to develop acute respiratory failure.

We hope that this study will help the study team to identify how best to use a more aggressive respiratory treatment strategy in a high risk trauma population (thoracic trauma or trauma patients requiring thoracic surgery, spine surgery, or open abdominal procedures) to try and decrease the need for intubation with mechanical ventilation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All patients consented will be randomly assigned into one of three groups: nasal cannula (control group, our current standard of care), high-flow nasal cannula, high-flow nasal cannula plus noninvasive ventilation.

After obtaining consent, patient will be randomized to interventions 1:1:1 within each of two groups: patients admitted to the ICU without being intubated OR intubated patients undergoing an extubation.

Randomization will be managed through RedCap. After consent, the treating clinician will log into RedCap to obtain the patient's treating assignment.

The primary outcome of interest is failure of conservative ventilation intervention in prevention of initial intubation or prevention of reintubation.

A chart review of all enrolled patients will be done quarterly to assess morbidity, mortality, and outcomes.

No placebo will be used as all qualifying patients will be placed on nasal cannula, high-flow nasal cannula, or high-flow nasal cannula plus noninvasive ventilation. All other treatments will be standard of care.

Participants in the study will continue until the patient is discharged from the trauma ICU.

The study will end when the last person enrolled has been discharged from the trauma ICU. If patient's participation ends prematurely, available data will be entered into the database and evaluated appropriately.

This study will take place at the OU Medical Center (OUMC) among patients admitted to the Trauma Intensive Care Unit.

Consent for study enrollment will take place at OUMC during discussion with physician providing trauma care and the patient, family member, or next of kin consenting for the study.

The following data will be collected and recorded: Supplemental oxygen requirements, Date/Time of arrival, Date/Time of Admission to ICU, Date/Time of intubation procedure, Date/Time of extubation, Ventilator settings, Duration of intubation, Comorbidities, PaCO2 values, PaO2 values, Vital signs at arrival and at admission to ICU, Age,Gender, Weight, Height, BMI, Traumatic injuries, Diagnosis, Past medical history/medical co-morbidities, Glasgow coma scale, Oxygen saturation, Negative inspiratory force score, Rapid shallow breathing index score, Pulmonary treatments, including an intolerance to therapy, Injury Severity Score (ISS) and/or Abbreviated Injury Scale (AIS).

Intervention Model

PARALLEL

Participants will be randomized into 1 of 3 interventions: nasal cannula, high flow nasal cannula, and high flow nasal cannula plus noninvasive ventilation within each of two groups: patients admitted to ICU without being intubated OR intubated patients undergoing an extubation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Not Intubated

Patients admitted with a trauma injury who do not need to be intubated to receive treatment. Intubated means putting a tube down your throat to keep your airway from collapsing. Participants will be randomized to receive one of the three interventions in this arm.

Group Type ACTIVE_COMPARATOR

Standard of Care - Nasal Cannula

Intervention Type OTHER

Standard of care. Flexible tube to provide extra oxygen when patients need a little help, but are not in respiratory distress.

High-flow nasal cannula

Intervention Type OTHER

Same as nasal cannula, except the oxygen is heated or humidified and the flow is stronger, pushing air into the lungs to help keep the airway open.

HFNC plus non-invasive ventilation

Intervention Type OTHER

This method uses HFNC as described above and adds noninvasive ventilation which is similar to CPAP machine and uses a mask rather than having to intubate (putting a tube down your throat to keep your airway from collapsing).

Intubated Patients Undergoing Extubation

Patients admitted with a trauma injury who had to be intubated for treatment of their injury. Interventions administered after the tube is extubated (removed from throat). Participants will be randomized to receive one of the three interventions in this arm.

Group Type ACTIVE_COMPARATOR

Standard of Care - Nasal Cannula

Intervention Type OTHER

Standard of care. Flexible tube to provide extra oxygen when patients need a little help, but are not in respiratory distress.
