Bilobar atelectasis after difficult tracheal intubation.

Acute intra-operative collapse of a lobe without apparent cause is rare. We report a case of transient bilobar atelectasis that developed without any apparent cause after a difficult tracheal intubation in a healthy young patient. Intrabronchial obstruction was ruled out by bronchoscopy. The bilobar atelectasis developed acutely and resolved quickly with mechanical ventilation. The characteristics of the lung collapse were atypical, suggesting either its reflex nature or acute reduction of lung volume owing to intubation-induced coughing. We present a review of the mechanisms of atelectasis.

Perioperative management of 63 patients with pheochromocytoma.

During a 10-year period, 60 patients with confirmed diagnoses of pheochromocytoma underwent a total of 63 surgical procedure. To control extreme blood pressure elevations, 6 patients received phenoxybenzamine preoperatively and 28 patients received prazosin. The remaining 29 patients received neither drug. Intravenous sodium nitroprusside and nitroglycerin, alone or in combination, were used in all but 10 patients to control intraoperative hypertensive episodes. One patient died after surgery due to pre-existing intracranial malignant tumor. All other patients were discharged from the hospital with no clinical evidence of stroke or myocardial infarction. We conclude that pheochromocytoma patients can undergo successful surgery without preoperative profound and long-lasting alpha adrenergic blockade.
