各種麻酔法の肺含水量に及ぼす影響に関する実験的研究 第1編 犬における肺含水量に関する実験的研究

1) Dogs were killed through three different ways: rapid intravenous injection of ravonal, cutting the abdominal aorta and heart block. The water content of the lungs was almost the same and independent of the procedures adopted. Between the right and left lungs no difference of water content was detected. 2) To evoke pulmonary edema ligation of the pulmonary lobe vein, injection of veratrin to the cystern, and pericardial tamponade to dogs with hypoproteinemia were performed. By the first and second only histological pulmonary stasis was made. However, by the last, both pulmonary stasis and edema could be developed. 3) The extent of the stasis was slight in the group of the ligated vein considerable in that of veratrin injection to cystern, and highest in that of pericardial tamponade. In 56.3% of this group fluid retention was observed in the alveoli. 4) The water content of the lungs was nearly parallel to the extent of stasis. The content increased markedly in the animals with pulmonary edema. Even in the animals with effusion in the alveoli, if the stasis was slight in extent, the water content increase was not significant.
