Weaning From Mechanical Ventilation in Patients With Acute Brain Injury

Acute brain injury (ABI) patients frequently necessate intubation and invasive mechanical ventilation (IMV). While some ABI patients are capable of breathing spontaneously, which is one of the main criteria of extubation and weaning. However, the rate of extubation failure was significantly higher in ABI patients compared with non-neurological critical care patients. In patients who have failed one or several trials of extubation, tracheostomy is recommend according to the latest ESICM consensus. Tracheostomy can enhance comfort, improve pulmonary hygiene and decrease sedation requirement, which could facilitate the liberation from ventilator. Numerous studies have explored the causes of weaning failure and provide various predictive models in guiding extubation and tracheostomy. Yet, due to limitations of such as small sample size or a lack of external validation, there is paucity of practical weaning algorithm tailored for ABI patients. The liberation from IMV in ABI patients still remains challenging with poor level of evidence in current guidelines or expert consensus. We aim to describe the weaning outcomes in ABI patients, and further investigate the potential predictors of weaning success in ABI patients.
