Abstract

THIS PAPER is first and foremost a contribution to the elucidation of the neurologic mechanism for the Trousseau and von Bonsdorff phenomena, with special regard to the changes in excitability of the nerve during and after ischemia. In the second place, it is intended to throw further light on the mechanism for the spontaneously occurring symptoms of tetany.

The Trousseau phenomenon signifies here the tetanic spasm following pneumatic compression of the arm, while the von Bonsdorff phenomenon means the facilitation of tetanic spasm induced by hyperventilation after preceding compression of the arm. Closer analysis shows, however, that not only the spasm but also the sensory symptoms of irritation of the typical spontaneous attack of tetany are obtained when these phenomena are precipitated. The spontaneous attack of tetany is, in fact, reproduced in detail. One may therefore expect to be able to find a single explanation of all three phenomena. It
