This study aims to assess, in terms of catheter salvage and economic cost, the effect of a low dose (2000 IU) urokinase lock technique to clear multilumen central venous catheters (CVC) and peripherally inserted central catheters (PICCs) when occluded. A total of 100 catheters were included in the analysis. Results indicate this lower dose technique to be effective in restoring the patency of multilumen CVCs, but not as effective when clearing PICCs. No catheters were lost because of occlusion.
本研究旨在从导管挽救和经济成本方面，评估低剂量（2000国际单位）尿激酶封管技术在清除多腔中心静脉导管（CVC）和外周静脉穿刺中心静脉导管（PICC）堵塞时的效果。分析共纳入100根导管。结果表明，这种低剂量技术在恢复多腔CVC通畅方面有效，但在清除PICC堵塞时效果不佳。没有导管因堵塞而丢失。
