The Cerebral-Respiratory Interaction During Spontaneous Breathing Ventilation in Neurosurgical Patients (CeRes-SB) — CeRes-SB  

Mechanical Ventilation Complication Clinical Trial

Official title:
Investigating the Effects of Expiratory Flow Limitation and the Effects of Spontaneous Breathing on Intracranial Pressure. An Observational Clinical Study on Neurosurgical Patients.

Clinical Trial Summary

Mechanical ventilation (MV) is a life-saving supportive therapy and one of the most common interventions implemented in intensive care. To date, only the inspiratory phase of breathing has been extensively investigated, and new MV methods have been implemented to reduce its harmful effects. Despite this, lung injury still occurs and propagates, causing multiorgan failure and patient deaths. The expiratory phase is considered unharmful and is not monitored or assisted during MV. In animal experiments, we recently showed that the loss of diaphragmatic contraction during expiration can harm the lungs during MV. During mechanical ventilation, the expiratory phase of breathing is completely disregarded. However, in all conditions that promote lung collapse, peripheral airways gradually compress and close throughout the expiration, potentially worsening lung injury. This cyclical lung collapse and consequent air-trapping may have an impact on the Starling resistor mechanisms that regulate venous return from the brain, potentially affecting cerebral perfusion and intracranial pressure. This study will investigate the incidence and the consequences of an uncontrolled expiration and expiratory lung collapse in spontaneously breathing critically ill neurosurgical patients during mechanical ventilation. Electrical impedance tomography measurements , oesophagus and gastric pressure, electrical activity of the diaphragm and intracranial pressure will be acquired in a synchronised manner during controlled mechanical ventilation, on a daily bases during assisted mechanical ventilation.
