The NEUROlogically-impaired Extubation Timing Trial (NEURO-ETT)

February 27, 2020 updated by: Dr. Damon Scales, Sunnybrook Health Sciences Centre

The NEUROlogically-impaired Extubation Timing Trial

This trial in brain-injured patients will test which of the following will lead to better patient outcomes: (1) an airway management pathway consisting of daily assessments and removal of the breathing tube as soon as patients can breathe on their own and appear able to protect their airway; versus (2) the usual treatment patients would have received if they were not enrolled in this trial.

Study Overview

Status

Status

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

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

Thousands of patients suffer severe brain injuries every year, from causes such as trauma, stroke, and infection. These patients are usually not fully awake and need help with their breathing and with preventing them from choking on their secretions. This is done with a breathing tube inserted through the mouth into the lungs and connected to a breathing machine. As patients recover, It is often unclear when the best time is to remove the breathing tube. Doctors might decide to remove it relatively early, or they may wait until the patient is more fully awake, or they may perform a tracheostomy (neck surgery to insert a new tube directly into the windpipe (trachea), replacing the temporary breathing tube). Each of these approaches has risks and benefits. This trial in brain-injured patients will test which of the following will lead to better patient outcomes: (1) an airway management pathway consisting of daily assessments and removal of the breathing tube as soon as patients can breathe on their own and appear able to protect their airway; versus (2) the usual treatment patients would have received if they were not enrolled in this trial.

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

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. Age > 16 years
  2. Acute brain injury (subarachnoid hemorrhage, diffuse axonal injury, ischemic stroke, intracerebral hemorrhage, brain tumor, global cerebral anoxia/cardiac arrest, meningitis/encephalitis, cerebral abscess, epidural hematoma, subdural hematoma, seizure) that occurred within the previous 4 weeks
  3. Receiving mechanical ventilation via endotracheal tube for ≥ 48 hours

Exclusion Criteria:

  1. Quadriplegic
  2. Neuromuscular disease that will result in prolong need for mechanical ventilation, including but not limited to Guillain-Barre syndrome, cervical spinal cord injury, advanced multiple sclerosis

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

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.
Active Comparator: Airway Management Pathway
An airway management pathway consisting of daily assessments and removal of the breathing tube as soon as patients can breathe on their own and appear able to protect their airway
Procedure: Airway Management Pathway
Patients in this group will receive several components that comprise airway management pathway: (1) daily spontaneous breathing trials (SBTs); (2) prompt extubation following successful extubation readiness criteria; (3) high-flow nasal oxygen for at least 24 hours following extubation.
Active Comparator: Usual Care
The usual clinical practice is often to keep the patient on artificial respiration for longer in the hope that the patient will wake up before removing the tube, or performing a tracheostomy if the patient doesn't wake up
Procedure: Usual Care
Patients in this group will be treated according to usual care, which may include extubation or tracheostomy timed according to treating physicians' discretion.
