1.本文对31例上腹部手术前后潮气末位置（ETP）与肺排空点（CP）的关系进行了研究。2. ETP-CP与肺泡动脉血氧分压差（A-ado 2）呈显著负相关。其中19名患者进行了迷走神经切断术和引流手术，在该组中，术后第一和第二天ETP的下降幅度大于CP。4.这表明，气道关闭是一个已知的低氧血症腹部手术后的一个促成因素。
1. The relationship between end tidal position (ETP) and the point of lung emptying at which there is significant airways closure (CP) has been investigated before and after upper abdominal surgery in thirty-one patients. 2. A significant negative correlation between the index (ETP-CP) and the alveolar-arterial P o 2 difference (A-ado 2 ) was found. 3. Nineteen of these patients had a vagotomy and drainage operation and, in this group, there was a greater fall in ETP than in CP in the first and second postoperative days. 4. It is suggested that airway closure is a contributory factor to the known hypoxaemia following abdominal surgery.
