Study type
Interventional
Description of intervention(s) / exposure
Post-neurosurgical and neurologic tracheotomized patients receiving mechanical ventilation will be randomized to receive either protocolized weaning protocol (intervention group) or a liberal weaning process according to the attending physicians’ clinical judgment (control group). In the intervention group, physiologic and clinical data collected in a systematic fashion by means of a written flow chart and a subsequent spontaneous breathing trial will determine if the patient will be disconnected from the ventilator.
The patients in the intervention group will be daily subjected to a spontaneous breathing trial consisting in a 30 min trial connected to the ventilator at 2 cmH2O of positive end expiratory pressure (PEEP). At the end of the 30 min a blood gas will be taken and the patient will be disconnected to the ventilator only if: the rapid shallow breathing index (ratio between respiratory rate and tidal volume) less than or equal to 105, the ratio between partial pressure of oxygen and fraction of inspired oxygen (PaO2/FiO2) greater or equal to 200 mmHg, and pH greater or equal to 7.35 with a PaCO2 less than or equal to 50 mmHg. If during the spontaneous breathing trial the patient will present any of these criteria i.e., breathing frequency greater than 35 breath/min; respiratory distress; SpO2 less than 90%; systolic blood pressure less than 90 or greater than 180 mmHg; heart rate greater than 140 bpm; deterioration of 2 points in the Glasgow Coma Scale, the spontaneous breathing trial will be interrupted and PEEP and Pressure Support will be set as before the weaning trial.

Comparator / control treatment
Control Group: The physician in charge will check daily patients for readiness to be disconnected to the ventilator. Despite the physician in charge will have available all the clinical information on rapid shallow breathing index, ratio between respiratory rate and tidal volume, pH and pCO2, the decision to disconnect the patient from the ventilator will depend not on a protocolized patient performance during the spontaneous breathing trial, but only on clinical judgment.

Outcomes
Primary outcome [1] 286131 0
Reduction (%) of weaning failure.
The weaning failure will be defined as number of patients who are reconnected to the ventilator in the following 48 hours after the disconnection over the total number of patients. As we expect a reduction of weaning failure in the Intervention group, the difference between the percentage of weaning failure between the Control and Intervention groups will be the Reduction (%) of weaning failure.
These data, can be assessed by looking at the medical records database available in our hospital.

First 48 hours after disconnection from ventilator
Secondary outcome [1] 295207 0
Hours of invasive mechanical ventilation.
In both groups, the hours of invasive mechanical ventilation will be counted from the enrolment (i.e., from the moment the hemodynamic, neurologic and respiratory parameters will be stable to allow the physician in charge to check daily the patient for readiness to be disconnected to the ventilator) to the discharge to the ICU or up to 28 days in the Intensive Care Unit.
These data, can be assessed by looking at the bedside chart data.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A computer-generated randomization list will be prepared by the statistician. Based on the list sequentially numbered sealed opaque envelopes containing cards with group assignments will be prepared by the statistician who is not involved in patients enrollment. These sealed envelopes marked with the patients' sequential numbers are kept at the ICU department. When a patient is enrolled and written informed consent obtained, the physician in charge of the patient opens the envelope with the lowest number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by computer software (computerised sequence generation)
Masking / blinding

Summary
Brief summary
Introduction: Although a life-saving intervention, mechanical ventilation is apt to unwanted side-effects and complications and should be interrupted as soon as possible. In acutely brain-injured patients, delaying weaning and liberation from mechanical ventilation increase the rate of ventilator-associated pneumonia, septic complications, and mortality. In neurologic and neurosurgical intubated patients, a systematic assessment of the patient’s potential to be weaned off the ventilator has been demonstrated to reduce the risk of re-intubation following extubation failure, compared to the sole physician’s clinical judgment.
Objective: We undertook this multicentre randomized controlled trial to evaluate whether a systematic approach to weaning is superior to the physician’s judgment in preventing weaning failure occurring within 48 hours, in neurologic patients undergoing mechanical ventilation through a tracheotomic cuffed tube.
Methods: neurosurgical and neurologic tracheotomized patients receiving mechanical ventilation will be randomized to receive either protocolized weaning protocol (intervention group, IG) or a liberal weaning process according to the attending physicians’ clinical judgment (control group, CG). Although in this last group the decision are left entirely to the discretion of the physicians, all the information collected and recorded for the IG will be also available. The criteria for protocol failure i.e., reconnection to the ventilator, are defined a priori. Patients will be considered successfully weaned if they are not reconnected to the ventilator in the following 48 hours.
