Abstract | OBJECTIVE: DESIGN: A blind clinical test with random distribution. SETTING: PATIENTS: A random sample of 50 patients with COPD who had received mechanical ventilation for more than 48 hours and who were considered to fulfill weaning criteria: resolution of the exacerbation of the COPD disease, Glasgow scale >10, temperature ≤ 38°C, PaO(2) /FiO(2) quotient >150 with an external PEEP ≤5cm H(2)O and FiO(2) ≤ to 50%, hemoglobin >10g/dl, no need for vasoactive drugs (except for dopamine ≤5μg/kg/min or dobutamine ≤5μg/kg/min) or for sedative agents and effective cough. INTERVENTION: A 30-minute spontaneous respiration trial with T-piece system or CPAP. VARIABLES: RESULTS: Out of 25 patients who were assigned to the T-tube group, 18 successfully completed the trial and were extubated; 3 of them requiring reintubation. Out of 25 patients who were assigned to the CPAP group, 19 were extubated and none of them required reintubation. There was successful weaning from mechanical ventilation in 76% in SBT-CPAP vs 60% in SBT-TT (relative risk 1.27; 95% confidence interval 0.86 to 1.87). CONCLUSION: In a COPD patient cohort, the performance of spontaneous breathing with CPAP showed a tendency to better outcome than with T-Piece, however, further research is needed.
