Intubation of the left main bronchus via a tracheostomy tube was performed in a patient with local recurrence of lung cancer associated with invasion and obstruction of the left main bronchus after right sleeve pneumonectomy. The result was satisfactory not only for preventing asphyxia, but also for maintaining the patency of the airway after extubation of the endotracheal tube.

Flexible suction catheters were passed through the endotracheal tubes of infants undergoing mechanical ventilation, just before chest radiographic examination for clinical purposes. With the head straight, 7 of 10 straight catheters entered the right main bronchus but with the head turned, 17 of 20 straight catheters and 19 of 20 curved tip catheters entered the contralateral bronchus.

A 25-year-old female patient presented with dry coughs of 20 days duration and fever for four days. Examination of respiratory system revealed no significant abnormality. Chest radiograph was normal. CT scan of the thorax revealed endobronchial opacity in the right main bronchus suggestive of a foreign body. Patient retrospectively recollected history of betel nut aspiration just prior to onset...

Anomalies of bronchial anatomy have been categorised as "displaced", when a normal bronchus arises from an abnormal site, and "supernumerary", when there is evidence that all normal bronchi are present, together with an additional bronchus.' In a 15-year period slightly more than 2500 bronchograms were made in the course of routine investigation of respiratory disease. Three bronchograms reveal...

A 6 month old infant presented with a history of cough and noisy breathing since 5 weeks of age. He had been evaluated many times in a local emergency department for episodes of cough, wheeze and retractions. His parents reported that his symptoms seemed to be worse when he was supine and did not respond well to steroids or bronchodilators. He had been feeding and growing normally. On examinati...

Bronchus-derived relaxing factor (BrDRF) decreases contractility of newborn rat pulmonary arteries (PA) and is dependent on nitric oxide (NO) synthesis. In vivo, this factor appears to gain access via the adventitial side of the PA. However, the adventitia has been reported to be a barrier to NO. We studied the effect of an adjacent bronchus on PA contractility to norepinephrine in nine juvenil...
