摘要:

AbstractIn dogs under ether or chloroform, stimulation of sensory nerves (saphenous, tibial, peroneal, sciatic, ulnar, and median) causes usually increased respiratory movements when narcosis is not profound or curare is not employed. These increased movements produce a fall of blood‐pressure, and when they are very violent, one cannot obtain any pressor reflex even with a strong stimulation. When much increased respiratory movements are prevented by very deep narcosis or brain compression, fall of blood‐pressure due to this cause does not occur. Mechanical interference with the circulation as a result of the increased movements of the thoracic walls seems to be the main cause of this fall, since it can be eliminated by opening the thorax. When this complication is not taken into careful consideration the results of vasomotor experiments are liable to be misinterpre
