在进入肺动脉的过程中，球囊的放气允许导管尖端暴露，这可能损伤心脏或肺，然后较慢的体积减小速率提供更大的安全性。我们发现，将球囊充盈至1.5 ml所需的压力在100至250 mmHg之间变化，表明顺应性范围很广。当用空气充气并暴露于75%N20时，三个高度顺应性的球囊迅速膨胀并在10分钟前破裂。因此，无法识别的球囊扩张或压力增加导致的创伤是真实的可能性。事实上，Barash等人1（2）最近建议将压力释放机制纳入球囊充盈端口，以便不会意外获得高压。我们的结论是，对于用一氧化二氮麻醉的病人，从各方面来看，用再循环气体混合物或用100%的CO来充盈球囊是可取的。詹姆斯B。纽约城市大学纽约西奈山医学院麻醉系，20029 Edmond I。埃格11岁，医学博士，加州大学麻醉系，San弗朗西斯科，CA 94143
deflation of the balloon during passage into the pulmonary artery allows exposure of the catheter tip, which may traumatize the heart or lungs, then a slower rate of volume decrease provides greater safety. We found that the pressure required to inflate the balloons to 1.5 ml varied from 100 to 250 torr indicating a wide range of compliance. Three highly compliant balloons expanded rapidly and ruptured before 10 minutes when inflated with air and exposed to 75% N20. Trauma resulting from unrecognized balloon expansion or pressure increase is therefore a real possibility. Indeed, Barash et a1 (2) have recently suggested that a pressure release mechanism be incorporated into the balloon inflation port so that inadvertent high pressure cannot be obtained. We conclude that for the patient anesthetized with nitrous oxide, it is desirable from all points of view, to inflate the balloon with either the re5pired gas mixture, or with 100% COs. James B.
