Zusammenfassung: | Although treatment of refractory atelectasis has been improved by pulmonary insufflation through FOB with balloon cuff,1 low pulmonary compliance and high critical opening pressure of alveoli in the atelectatic areas require a more selective approach to prevent pressure dispersion to highly compliant zones. To achieve the highest insufflation selectivity and reduce patient discomfort, we have devised a small caliber balloon-tipped catheter to easily reach even the minor branches of the bronchial tree. This result was obtained by utilizing the preformed curve of the catheter distal end after withdrawing the internal stylet. The catheter was introduced through the nostrils (16 patients) or through an endotracheal tube (two patients) and advanced under fluoroscopic guidance. Reexpansion of atelectatic areas was accomplished by repeated air injections through a 60-ml syringe. No complications were observed. Complete disappearance of x-ray film evidence of atelectasis was obtained in 15 patients and partial reexpansion in 3 patients. |
