| Abstract | 「要旨」特別に作製した時間設定/流量規定の高圧吹送人工呼吸器を用い, 肺内圧を上昇させ, 肺血管床血液を左房, 左室, 大動脈と駆出することにより, 心蘇生時の人工心マッサージに応用することを全身麻酔下に人為心停止が導入された雑種成犬12頭で試みた. すなわち胸腹部全周に加圧性圧迫帯を装着し, 気道内圧が上昇しても肺胞損傷が生じないよう防御したうえで, 1.5〜1.8気圧, 1回換気量30〜35ml/kgで純酸素による肺内加圧を人工呼吸も兼ねて行った. そして種々の吹送条件を予備実験として4頭の動物を用いて検討した結果, 吹送/呼出時間比=1:1, 吹送回数=60/分でもっとも効果的な血液駆出が行われることがみとめられた. 次に8頭の動物において上記条件をもって心蘇生が試みられた. 本法に併せて電気的除細動も併用されたが, 心蘇生には成功しなかった. すなわち本法では静脈側からのback pressureのために十分な冠血流量がえられないためと考えられた. |

| Abstract | High pressure lung inflation via an endotracheal tube was applied to squeeze the blood from the pulmonary vascular beds into the left heart chambers and further to push it into the peripheral capillaries in 12 dogs, in which ventricular fibrillation had been induced by AC shock, as substitute of conventional external cardiac massage with sternal compression. The lower chest and upper abdomen were compressed by two air tourniquets with 2 A TA. The animals were ventilated in tidal volume of 30〜35 ml/kg with 1500-1800 mm H2O pressurized pure oxygen. The ventilatory frequency and inflation/deflation ratio were varied to obtain maximum systolic pressure of the subclavian artery and maximum flow rate in the carotid artery, in the 4 animals and the best combination of ventilatory frequency of 60 times/min. with 1 : 1 of inflation/deflation ratio was determined. Practical cardiac resuscitation was carried out in the remained 8 animals, who were left in place for one minute after ventricular fibrillation induced, by the means as mentioned above. |
