He expressed the opinion, as did Irvine and Turnacliff, 4 that treatment with liquid oxygen caused much less pain than did treatment with solid carbon dioxide. All observed that the pain was much less if the freezing were confined to the lesions than if the adjacent tissue were also frozen. Irvine and Turnacliff 4 reviewed the literature up to 1929 and related their experiences with the use of liquid oxygen. They were favorably impressed with the results which they obtained. In a discussion of this paper, Pusey stated that he conceived the |
