[An economical procedure for one-stage bronchofibroscopy and bronchography]. / Un procédé économique de bronchofibroscopie et bronchographie en un temps.

A fibreoptic bronchoscope is now commonplace as equipment for the respiratory physician. It can be used to facilitate and improve bronchography by certain technical modifications. First a fibreoptic bronchoscopy is performed by the nasal route. In this way bronchial lesions and anatomical variants can be seen. A careful aspiration of the bronchi to be examined as well as local anaesthesia bronchus by bronchus is performed. The fibreoptic scope is then withdrawn to the oropharynx, enabling a superior view of the larynx. A Métras catheter, whose angle is modified by the biopsy forceps is introduced into the free nostril and the catheter is easily passed between the vocal cords under the direct view of the fibreoptic scope. Thus, except for the Métras catheter which remains indispensable, one can pass all the long standing material that has been used in this examination. In addition the achievement of fiberoscopy and bronchography at the same time seems to us both a better technique and an appreciable saving of time. Since 1980, 40 bronchographies have been performed with this technique, with no failures.

[General anesthesia for bronchoscopy and lipidol bronchography in children and infants]. / Anesthésie générale pour bronchoscopie et bronchographie lipiodolée chez l'enfant et le nourrisson

In 160 cases of children and infants, a technique of general anesthesia is described (penthiobarbital-suxamethonium, then halothane-oxygen with a mask in spontaneous ventilation if the bronchoscopy is followed by lipiodol bronchography). This technique is simple and efficacious and makes the child comfortable, especially in cases of repeated operation, and for the operator whose gestures are more rapid and less traumatising and this permits rapid awakening. No incidents or severe complications were noted.

[Characteristics of manifestations of border effect in electroroentgenobronchography]. / Osobennosti proiavleniia kraevogo effekta pri elektrorentgenobronkhografii

Specificity of the image reflecting the outlines of the bronchial lumena on the electroroentgenograms is explained by the manifestation of the border effect. The latter is caused by the non-uniformity of the electric field over the surface of the selenium layer with a regular distribution of charges. With electroroentgenography of sharply contrasted objects in a little contrast medium the potential relief has highly pronounced differences, this leading to distorsion of the dimensions and the shape of the objects under examination. When interpreting electroroentgenograms these specific features should be taken into consideration. In constructing improved medical radiographic equipment it will be advisable to envisage the possibility of controlling the said effect.
