Effect of Increased Muscular Work During Different Weaning Strategies in Critically Ill Patients
Recruitment status was Recruiting
Most patients admitted to intensive care units require mechanical ventilation. Weaning from assisted/controlled ventilation begins when we recognize that the patient has recovered adeguately from acute respiratory failure.
If weaning is delayed, costs are increased, as are the risks of nosocomial pneumonia, cardiac-associated morbility, and death. On the other hand, weaning too soon often results in reintubation, which is associated with complications similar to those of prolonged ventilation.
The aim of this trial is to establish an evidence-based approach to weaning and to determine when a patient is ready to be weaned from mechanical ventilation, and what is the best weaning technique.
|Study Design:||Allocation: Randomized

Masking: Open Label
Primary Purpose: Treatment
- 1. Days of intubation 2. Days of mechanical ventilation [ Time Frame: 28 days ]
- 1. The day of eventual tracheostomy 2. Organ Failure 3. The mortality at 28° day 4. Outcome at 6 months [ Time Frame: 1 year ]
|Study Start Date:||February 2005|
BIPAP (Bilevel Positive Airway Pressure) targeted on: TV 6-8 ml/kg, total RR 10-30/min, PEEP and FiO2 regulated on Sat greater than 92% (with spontaneous RR between 20-40%)
PSV (pressure support ventilation) targeted on: TV 6-8 ml/kg,total RR 10-30/min, PEEP and FiO2 regulated on Sat greater than 92, a minimum of 7 cmH2O of PS is tolerated.
PSV+CPAP (continuous positive airway pressure) targeted on: PSV: TV 6-8 ml/kg,total RR 10-30/min, PEEP and FiO2 regulated on Sat greater than 92, a minimum of 7 cmH2O of PS is tolerated, CPAP (5-10 cmH2O) at least 2 hours a day. If during the CPAP periods at least 1 of the criteria T tube test failure occurs, the patients will come back immediately to PSV.
