background: pleurotomy during coronary artery bypass grafting (cabg) may cause post-operative events, mostly pulmonary complications. in this study, we evaluated the influence of pleurotomy during cabg on the clinical outcome following left internal mammary artery (lima) harvesting. methods: between march and august 2009, 102 patients who underwent cardiac surgery were enrolled in this study an...

A 28-year-old neuromuscular patient chronically treated with nocturnal noninvasive ventilation developed pulmonary lobar atelectasis and daytime hypoxemia. Twenty four-hour 5L/min oxygen was begun, while mechanical cough assist aids were applied for seven days. In the following three days, treatment with nebulized Dornase alpha (rhDNase) b.i.d. was tested, without any significant improvement. O...

Isolated atelectasis of the middle lobe has been known for many years as the "middle lobe syndrome". Several clinical studies have shown that it may bae caused by malignant tumours. A 10-year study of 135 patients with isolated middle lobe atelectasis is presented. Fifty-eight patients (43%) had malignant tumours. Of 38 who had a thoracotomy, lung resection was possible in 25. In 20 patients re...

In a patient with lobar atelectasis who was on positive pressure ventilatory support, ventilation and perfusion images showed absent ventilation and normal perfusion (reverse mismatch) in the region of the atelectasis and normal ventilation and decreased perfusion (true mismatch) not caused by pulmonary embolism in another lung zone. We report this case to emphasize that the lung scan findings ...

Lungs of unselected cadavers were fixed at necropsy using a formalin vapour technique. "Band shadows" were identified in the excised lungs and these were correlated with in vivo radiographs and with the morphological changes in the lung. Persistent shadows were produced by pulmonary infarction, subsegmental atelectasis, and septal fibrosis singly and in combination. Potentially transient shadow...

The relationship between changes in the viscosity of sputum and the development of pulmonary atelectasis has been discussed.15 The fibers found in sputum which appear to be responsible for the viscosity are

BACKGROUND Some critically ill patients have difficulty in mobilizing their respiratory secretions. These patients can develop pulmonary atelectasis that may result in hypoxemia. There are some data to show that atelectasis may be prevented by turning a patient from side to side utilizing special beds. STUDY OBJECTIVES To determine the role of kinetic therapy (KT) combined with mechanical per...
