Monitoring brain activity during mechanical ventilation

Impact of Mechanical Ventilation on Hippocampal Oscillation and Respiratory-hippocampus Coupling

Beijing Sanbo Brain Hospital · NCT06480162

This study is testing how mechanical ventilation affects brain activity in ICU patients, especially those with drug-resistant epilepsy, to see if we can prevent brain injury while they are being weaned off the ventilator.

What this trial studies

This observational study investigates the impact of mechanical ventilation on the hippocampus in ICU patients, particularly focusing on ventilator-associated brain injury (VABI). It aims to monitor hippocampal EEG activity while patients are weaned off mechanical ventilation, exploring the relationship between breathing patterns and hippocampal activity. Patients with drug-resistant epilepsy will have simultaneous intracranial EEG recordings and respiratory data collected during various mechanical ventilation scenarios. The study seeks to clarify the effects of mechanical ventilation on brain function and the potential for preventing VABI.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with drug-resistant epilepsy who are scheduled for stereoelectroencephalography.

Not a fit: Patients with recent seizures, structural brain damage, cognitive impairment, or those who have been mechanically ventilated for more than 24 hours may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and prevention of brain injuries associated with mechanical ventilation in critically ill patients.

How similar studies have performed: While there is substantial preclinical evidence regarding the effects of mechanical ventilation on the brain, this specific approach in human patients is novel and has not been extensively tested.
