NCT06511986

Brief Summary

Ventilator-associated pneumonia (VAP) is a common infection in critically ill patients, especially those with acute brain injuries, leading to increased mortality and longer ICU stays. The mechanical insufflation/exsufflation (M-I/E) cough assist device improves outcomes in patients with neuromuscular disorders but its effects on brain-injured patients are largely unknown. This study is conducted at a tertiary neurosurgical medical center and consists of two substudies. The prospective physiological study assessed the impact of M-I/E on hemodynamics and ICP in mechanically ventilated neurosurgical patients. The combined retrospective-prospective clinical study was performed to investigate the efficacy of M-I/E on occurence of VAP and other clinical outcomes.

Outcome Measures

Primary Outcomes (3)

  • Mean blood pressure

    In study one, mean blood pressure will be recorded during the incremental pressure changes in the study one

    during the process of physiological study, up to 2 hours

  • Heart rate

    In study one, heart rate will be recorded during the incremental pressure changes in the study one

    During the process of physiological study, up to 2 hours

  • Rate of ventilator associated pneumonia

    In study two, ventilator associated pneumonia is defined as pneumonia occurring in patients who have been mechanically ventilated for at least 48 hours. Pneumonia was diagnosed by clinical features (e.g., cough, fever, pleuritic chest pain) and by lung imaging. To derived the diagnosis of pneumonia, patient electronical record, lab results, and images were extracted from the electronical system.

    Within 7 days after the onset of mechanical of ventilation

Secondary Outcomes (4)

  • Intracranial pressure

    During the process of physiological study, up to 2 hours

  • Length of stay in ICU

    Patients will be followed up until 28 days after surgery, discharged from hospital or dead, which ever came first,through study completion, an average of 1 year

  • Length of hospital stay

    Patients will be followed up until 28 days after surgery, discharged from hospital or dead, which ever came firstthrough study completion, an average of 1 year

  • Days of receiving mechanical ventilation

    Patients will be followed up until 28 days after surgery, discharged from hospital or dead, which ever came firstthrough study completion, an average of 1 year
