Studies of care of patients with central venous catheters report a 3-7% incidence of catheter-induced sepsis when sterile gauze and tape are used as an occlusive dressing. The technique requires that the dressing be changed three times each week for catheterization site inspection. From June 1979 to September 1980, a noncomparative evaluation of a transparent, self-adhesive, polyurethane dressing which is permeable to water vapor but not bacteria was performed. This dressing was used for the care of 100 consecutive patients with central venous catheters. Dressing life averaged 5.3 days with silicone rubber catheters and 4.3 days for polyvinyl chloride catheters. One patient developed catheter induced sepsis (incidence 1%). This dressing material: (1) is acceptable for use as a dressing of central venous catheters; (2) continuously permits inspection of the insertion sites; (3) decreases nursing hours; (4) provides a comfortable dressing which secures the catheter to the patient; and (5) is durable even when exposed to high humidity therapy devices, or when possible permits the patient to take showers.
关于中心静脉导管患者护理的研究报告称，当使用无菌纱布和胶带作为封闭敷料时，导管相关败血症的发生率为3%-7%。该技术要求每周更换三次敷料以检查导管插入部位。1979年6月至1980年9月，对一种透明、自粘、可透水蒸气但不透细菌的聚氨酯敷料进行了非对比性评估。该敷料用于连续100例中心静脉导管患者的护理。硅胶导管的敷料平均使用时长为5.3天，聚氯乙烯导管为4.3天。1例患者发生导管相关败血症（发生率1%）。这种敷料材料：（1）可作为中心静脉导管的敷料使用；（2）可持续检查插入部位；（3）减少护理时间；（4）提供舒适的敷料，将导管固定于患者身上；（5）即使暴露于高湿度治疗设备中或患者可能淋浴时也耐用。
