Klappentext zu „Thermographic Investigations into the Physiological Basis of Regional Anaesthesia “
The existence of a differential block is still part of the theory of regional anaesthesia. In 1980 it was described in detail by Cousins and Bridenbough in their standard work Neural Blockade. The theory of differential sensitivity of fibres in the peripheral nervous system essentially goes back to Gasser and Erlanger, who in 1929 established that when isolated peripheral nerves are electri cally stimulated in the presence of increasing concentrations of co caine, the compound action potentials of slow-conducting fibres are blocked before those of fast-conducting fibres show any measur able changes. In man, regional anaesthesia begins subjectively with a feeling of warmth, objectively with a corresponding increase in skin tem perature. There is then, in order of occurence, loss of sensation of cold, heat and pain, and pressure and touch, and fmally loss of voluntary motoricity. In recovery from anaesthesia, these return in the reverse order. The theory of differential block is byno means undisputed. In 1981, de Jong, commenting in Anesthesiology on the work pub lished in that journal by Gissen et al. which showed a new sequence of differential sensitivity in the rabbit, wrote, "There remains plen ty to be done yet before the book on differential nerve block can be closed".
