RESUMEN
There is no universally acceptable protocol for the withdrawal of non-invasive ventilation (NIV) in chronic obstructive pulmonary disease (COPD) patients presenting with acute hypercapnic respiratory failure (AHcRF). This study was carried out to evaluate immediate against stepwise reduction in NIV. Sixty COPD patients with AHcRF who were managed with NIV were randomized into two groups - immediate NIV withdrawal (Group A), and stepwise reduction of NIV duration (Group B). The rate of successful NIV withdrawal, time to recurrence of hypercapnic respiratory failure, total duration of NIV use, and hospital length of stay (LOS), were compared among the 2 groups. NIV was successfully withdrawn in 51/60 (85%) patients. NIV was successfully withdrawn in 24/30 (80%) patients in Group A and 27/30 (90%) patients in Group B (p=0.472). The total duration of NIV use was significantly lower in Group A (38.97±17 hours) as compared to Group B (64.3±7.74 hours) (p<0.0001). The hospital LOS was significantly lower in group A (5.8±1.6 days) as compared to Group B (7.7±0.61 days) (p<0.0001). To conclude, immediate withdrawal of the NIV after recovery of respiratory failure among patients with exacerbation of COPD is feasible and does not increase the risk of weaning failure.

Mounier-Kuhn syndrome (MKS) is a rare disease of unknown etiology characterized by abnormal pathologic dilatation of tracheabronchial tree. The diagnosis of MKS is normally made on CT scan of chest on the basis of enlarged diameters of trachea and main stem bronchi. We are presenting histologically confirmed case of MKS, where the diameter of right main bronchus is below minimum diameter (mean+3 SD) required for the diagnosis. We suggest that the diagnosis of MKS should not be solely based on fixed criteria such as the diameter of airways, but on the basis of the overall clinical, pathologic, and radiologic profile.
