Identifying the optimal time of extubation in a brain injured population should improve patient outcome. Brain injured patients usually remain intubated due to concerns of airway maintenance. Current practice argues that unconscious patients need to remain intubated to protect their airways. More recent data however suggests that delaying extubation in this population increases pneumonias and worsens patient outcomes.

We designed a safety and feasibility study of randomizing brain injured patients into early or delayed extubation. The purpose was to gain insight into patient safety concerns and to obtain estimates of sample size needed for a larger study.

Enrollment: 16
Study Start Date: August 2004
Study Completion Date: May 2006
Primary Completion Date: May 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: armA I
Patients remain intubated until the patients Glasgow coma score improves to greater than 8.
Procedure: continued intubation
patients remain intubated until their Glasgow coma scores improve to greater than 8.
Experimental: arm 2
Patients that meet standard airway and ventilatory criteria for extubation but have a Glasgow coma score of less than or equal to 8 are immediately extubated.
Procedure: extubation
Brian injured patients that remained intubation solely because of a depressed level of consciousness were randomized into immediate extubation or delayed extubation until their level of consciousness improved.All patients met standard ventilatory, and airway criteria for extubation.

  3. Adequate ventilation.
  4. Respiratory rate to tidal volume ratio <105.
  5. Core body temperature < 38 degrees celsius.
  6. Hemoglobin > 8 grams per deciliter.
  7. No sedative medications for 2 hours.

Neurological requirements included:

  1. GCS ≤ 8.
  2. Intracranial pressure (ICP) < 15 cm of water and a cerebral perfusion pressure (CPP) > 60 mm Hg for patients with intracranial pressure monitors.

Exclusion Criteria:
