NCT06480162

Brief Summary

Ventilator-associated brain injury (VABI) frequently occurs in ICU patients. Although animal studies indicate the hippocampus as a key target of VABI, its relevance in human patients remains uncertain. In this study, the investigators aim to monitor hippocampal EEG activity during the weaning process of patients off mechanical ventilation, and also exploring the coupling between breathing patterns and hippocampal activity.

Outcome Measures

Primary Outcomes (1)

  • intracranial EEG (iEEG) recording of the hippocampus

    The iEEG data from each patient will be analyzed using Python (version 3.12.4). The data will be represented as power spectral density, also known as the power spectrum or spectrum, which measures the frequency distribution of energy or power within a signal. The power spectrum for each channel will be computed using the Fast Fourier Transform (FFT).

    During the process of weaning off mechanical ventilation, assessed up to 3 hours.

Interventions

After replacing the electrode, we'll monitor the EEG activity of the hippocampus and other cortex regions while weaning off mechanical ventilation.
