AbstractPatients suffering from advanced chronic thoracic disorders are at higher risk to develop respiratory failure, requiring mechanical ventilation. Forty seven patients acutely decompensated were investigated. Twenty nine of them were primarily ventilated noninvasively, 7 were intubated and 11 had been intubated and tracheotomized prior to arriving at the weaning center. All intubated patients were transferred to noninvasive ventilation within 24 h after arrival. Ten of the 11 tracheotomizd patients were transferred to noninvasive ventilation before discharge. One remained tracheotomized because of severe tracheal stenosis, despite being able to breathe spontaneously for several hours. Mortality was 14.2% in the intubated, 9% in the tracheotomized, and 10.2% in the primarily nasally ventilated. One patient refused to go on with mechanical ventilation and died. Hospital stay ranged between 4 and 24 days in the nasally ventilated. The intubated were ventilated invasively between 3 and 16 days and thereafter 4 to 17 days noninvasively on a regular ward. Tracheotomized patients were treated in intensive care for 7 to 32 days and in the weaning unit for 7 to 39 days. We conclude that patients either ventilated nasally or intubated or tracheotomized can be prepared for home mechanical ventilation in a weaning unit with similar outcome. Noninvasive ventilation is highly important in such patients as only one remained on invasive ventilation. This may implicate that transfer to noninvasive ventilation prior to tracheotomy might be appropriate.
