Study Type: Interventional
Official Title: Mechanical Ventilation in Severe Brain Injury: The Effect of Positive End Expiratory Pressure on Intracranial Pressure
Brief Summary: The purpose of this study is to collect physiologic data from patients with severe brain injury who require mechanical ventilation in order to describe the impact of ventilation, specifically positive end expiratory pressure (PEEP), on intracranial pressure (ICP).
Detailed Summary:
Sponsor: Beth Israel Deaconess Medical Center
Current Primary Outcome: Association between PEEP and ICP [ Time Frame: Change from baseline to 20 minutes ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Association between transpulmonary pressure and ICP [ Time Frame: Change from baseline to 20 minutes ]Transpulmonary pressure will be measured and recorded using an esophageal balloon catheter placed for research purposes. The association between transpulmonary pressure change with titration of PEEP and intracranial pressure will be analyzed as a secondary outcome.
- Association between PEEP and cerebral hemodynamics [ Time Frame: Change from baseline to 20 minutes ]Cerebral hemodynamic information will be recorded and calculated; Transcranial Doppler will be used to obtain some of this data. The association between positive end expiratory pressure and cerebral hemodynamics will be analyzed as a secondary outcome.
Original Secondary Outcome: Same as current
