Over the 48-month period from January 1983 through December 1986, 51 single-lumen (SL) and 94 double-lumen (DL) indwelling central venous (Hickman) catheters were placed in 118 patients with malignant disease. We reviewed these cases retrospectively to determine the types and frequency of complications requiring catheter removal. The catheters were in place a total of 18,397 days. Overall, 14% (7/51) of SL and 21% (20/94) of DL catheters were removed due to infection. Of those catheters becoming infected, DL catheters were infected earlier. SL catheters that became infected averaged 213 days of use before removal, whereas DL catheters becoming infected averaged only 78 days before removal (P less than or equal to .02). The infection rate was significantly less in SL (one infection per 1,210 days) than in DL catheters (one infection per 496 days) (P less than or equal to .02). Thus because of its significantly reduced risk of infection, the single-lumen Hickman may be the preferred catheter for long-term venous access in many patients.
在1983年1月至1986年12月的48个月期间，为118例恶性疾病患者置入了51根单腔（SL）和94根双腔（DL）留置中心静脉（希克曼）导管。我们对这些病例进行了回顾性研究，以确定需要拔除导管的并发症类型和发生率。导管总共留置了18397天。总体而言，14%（7/51）的SL导管和21%（20/94）的DL导管因感染而被拔除。在那些发生感染的导管中，DL导管感染更早。发生感染的SL导管在拔除前平均使用213天，而发生感染的DL导管在拔除前平均仅使用78天（P≤0.02）。SL导管的感染率（每1210天发生1次感染）显著低于DL导管（每496天发生1次感染）（P≤0.02）。因此，由于单腔希克曼导管感染风险显著降低，在许多患者中它可能是长期静脉通路的首选导管。
