Of the many possible causes of air embolism occurring in patients undergoing cardiopulmonary bypass (CPB), human error due to the perfusionist or the surgeon accounts for the vast majority. This case, however, presents a previously unreported, but recognized, cause of air embolism, due to a technical problem encountered during the administration of blood cardioplegia. The nature of some of the older CPB pumps allows the administration of cardioplegia at a time when the main CPB pump is not rotating. A situation may then arise whereby air may be entrained and delivered to the patient. The management of massive air embolism is discussed, and recommendations are made to prevent such an occurrence happening in the future.
在接受体外循环(CPB)的患者发生空气栓塞的众多可能原因中,灌注师或外科医生的人为失误占了绝大多数。然而,本病例呈现了一个此前未报告但已被认识到的空气栓塞原因,即血液心脏停搏液给药过程中遇到的技术问题。一些老式CPB泵的特性使得在主CPB泵不转动时能够给药心脏停搏液。这样一来,就可能出现空气被卷入并输送给患者的情况。文中讨论了大量空气栓塞的处理方法,并提出了预防此类情况在未来发生的建议。
