[Effect of pulmonary reventilation on gas exchange after cryolytic removal of obstruction in endobronchial tumors]. / Effetti sullo scambio gassoso della reventilazione polmonare dopo disostruzione criolitica nei tumori endobronchiali.

Blood gas analysis was used to assess the value of cryolytic endobronchial disobstruction in functional recovery of the reventilated lung parenchyma, with particular reference to the real improvement brought about in blood gas equilibrium by reventilation. Blood gas analysis was carried out in 5 cases of malignant tracheobronchial neoplasia (3 with atelectasis or subatelectasis) before and after disobstruction. Improved gas exchange, primarily in the form of better blood oxygen values, was noted in all cases, with a mean improvement of 28% in 3 cases and 7% in 2. It should be noted, however, that there was no correspondence between the results and the presence or otherwise of radiological evidence of atelectasis prior to the treatment.

[Endobronchopulmonary therapy with a permanent trans-crico-thyroid probe]. / Terapia endobroncopolomonare con sonda permanente trans-crico-tiroidea.

The possibilities of treating chronic bronchopneumopathies of various nature by means of permanent endobronchial transcricothyroid probe are examined with reference to 6 cases representing patients under treatment at the time this paper was being prepared (2 cases of chronic pulmonary TB, 2 of suppurating bronchiectasis, 1 of middle lobe syndrome and 1 of tracheal carcinoma). The series examined confirms the usefulness of this type of treatment as a back-up to traditional medical treatment where this alone failed to achieve the necessary results. Stress is laid on the good tolerance of the TCT probe presented by all patients, including a five-year-old boy.
