In a preceding communication¹ the existence of anoxic anoxia during ether anesthesia was demonstrated. Spinal or subarachnoid anesthesia is used frequently in surgical procedures, and it is therefore desirable to investigate the effects of spinal anesthesia on the oxygen in the arterial and in the venous blood.

Seevers and Waters² stated that the oxygen content in the arterial and in the venous blood is lowered during spinal anesthesia. However, they used large enough doses of drugs to produce respiratory paralysis, which rarely occurs in clinical surgical procedures. They did not present any data to show the degree of change in the blood oxygen. On the other hand, Nowak noted no significant changes in the oxygen of the arterial blood of cats under spinal anesthesia.³

In the present investigation we have undertaken to confirm and extend the observations of the previous investigators on the oxygen in the arterial . . . [Full Text PDF of this Article]
