作者于1973年报导“呼吸结构的冷冻手术(气管、支气管冷冻)”一文,该实验是在3只杂种狗身上作的,在这个基础上又给5只猴子中的4 只作了肺部冷冻实验(1只对照)。动物麻醉后按无菌操作开胸,暴露右肺中叶、下叶,将冷冻探头于右肺中叶冷冻3—4处(其中有2只同时冷冻下叶)。探头用液氮冷却,维持在-170℃,冷冻时将探头向肺实质压迫使其呈萎陷状,每次2分钟,使组织温度低于-60℃,待其自行完全融解后再重复冷冻,共3次。
The author, in 1973, entitled “Cryosurgery of the respiratory structure (trachea, bronchial freezing)”, was performed on three hybrid dogs, and on this basis, four of the five monkeys were also subjected to lung freezing Experiment (1 control). After anesthesia, the animals were thoracotomy aseptically and the middle and lower leaves of the right lung were exposed. The frozen probes were frozen in the middle of the right lung by 3-4 points (two of them were frozen at the same time). Probe cooling with liquid nitrogen, maintained at -170 ℃, freezing the probe to the lung parenchyma pressure so that it was collapsed, each 2 minutes, the tissue temperature below -60 ℃, to be completely self-melting after repeated freezing , A total of 3 times.
