[The popliteo-femoral block, a rarely used form of regional anesthesia. With special reference to the use of peripheral nerve stimulators]. / Der Popliteo-Femoral Block, eine selten angewandte Form der Regionalanaesthesie. Mit besonderer Berücksichtigung der Anwendung eines peripheren Nervenstimulators.

Blockade of the sciatic nerve in the fossa poplitea is a rarely used form of regional anaesthesia. A new method of identification of the tibial and peroneal nerve and their blockade in combination with blockade of the femoral nerve using a peripheral nerve stimulator, is described. Results in 300 patients during a 12 month period are described and discussed.

[Proceedings: Home treatment of chronic respiratory insufficiency: carrier solutions for aerosol inhalations]. / Heimbehandlung der chronischen Ateminsuffizienz: Trägerlösungen für Aerosolinhalationen

The excellent bronchodilatory effect of inhalation is widely accepted today. In order to obtain good results, correct instruction of the patient and correct choice of the nebulizer and inhalation solution are necessary. The performance requirements of the nebulizer and the most frequently used carrier solutions are critically discussed.

[Comparison of Tyloxapol (Tacholiquin, Alevaire) with physiological saline as inhalation carrier solutions]. / Vergleich von Tyloxapol (Tacholiquin, Alevaire) mit physiologischer Kochsalzlösung als Inhalationsträgerlösungen

By means of a double-blind crossover study the effects of tyloxapol (Tacholiquin, Alevaire) and saline as carrier solutions for the inhalation of beta-agonists have been compared in 24 paitents with bronchial asthma. Specific airway conductance was measured repeatedly over a 2-hour period in order to assess changes of airway caliber due to the inhalation. The results reveal a significant bronchoconstrictive effect of tyloxapol as compared with saline. The bronchodilator activity of solutions with tyloxapol and beta-agonists (orciprenaline, salbutamol) was no better than those with saline and the same beta-agonists. However, side effects (symptoms of airway irritation, increase of pulse rate) were more pronounced with tyloxapol. In view of the direct effects of inhalation with a beta-agonist, no advantage of the expensive carrier solution tyloxapol over saline could be shown.

[The inhalation of beta stimulators. Effect of the inhaled aerosol deposited in the oropharynx and in the bronchial tree]. / Die Inhalation von beta-Stimulatoren Wirkung des im Oropharynx und des im Bronchialbaum angelagerten Anteils des Inhalats

Inhaled aerosols are predominatly deposited in the oropharynx and only a minor portion penetrates into the sublaryngeal airways. The effectiveness of both components of an orciprenaline aerosol was tested in 12 asthmatics. For this purpose they were given an inhalation on one day and, on the next, the entire oropharynx was sprayed with the inhalant. Evaluation of the corresponding bronchodilator effects was based on repeated measurements of specific airway conductance. The results show that the inhalation is about 6 times as effective as the spray, and thus prove the superiority of inhalation therapy over oral or peroral medication with beta-stimulants in the treatment of bronchial asthma.
