Valuable haemodynamic data can be derived from a properly positioned Swan-Ganz catheter. Unfortunately, a significant number of these catheters will, for one reason or another, become malpositioned. Withdrawing a catheter from a permanently wedged position presents little difficulty. Repositioning may, however, necessitate its advancement, with the attendant risk of bacterial contamination. We have solved this problem by making a protective sleeve from readily available latex drain and tubing, which fits securely over the haemostatic valve of a No. 8F Cordis introducer. Iodine solution is injected into the sleeve to provide a sterile environment for the Swan-Ganz catheter, which can then be repositioned as required without the risk of bacterial contamination, as verified by bacteriological studies.
通过正确放置的 Swan-Ganz 导管可以获得有价值的血流动力学数据。不幸的是，由于种种原因，相当数量的这类导管会发生位置不当。将导管从永久楔入位置拔出没有太大困难。然而，重新定位可能需要推进导管，随之而来的是细菌污染的风险。我们通过用现成的乳胶引流管和导管制作一个保护套解决了这个问题，该保护套能牢固地套在 8F Cordis 穿刺导管的止血阀上。将碘溶液注入保护套内，为 Swan-Ganz 导管提供无菌环境，然后可根据需要重新定位导管，且无细菌污染风险，这已得到细菌学研究的证实。
