Central venous catheters are widely used in the care of critically ill patients. This paper reviews our experience with central lines in paediatric patients requiring intensive care, between the period August 1994 and August 1995. A total of 57 insertions were performed in 40 patients, all less than 12 years of age. We found that the most common indication for catheter use was nutritional support (40%). The overall complication rate was 58%. Catheter-related infection was the most serious problem, occurring in 32% of all insertions. Coagulase-negative Staphylococcus aureus was the organism most frequently isolated. Maintenance problems affected 17 of our catheters in which 9 were blocked. Both infected and blocked catheters were promptly removed. We had 3 cases of perforation and 2 cases of thrombosis. There were no deaths directly attributed to catheter use. Recommendations made include: 1) staff education and new guidelines for catheter care, 2) use of bacteria filters, 3) careful prospective monitoring of catheter infection rate, 4) heparinisation when infusion rate less than 2 ml/h, 5) eliminate use of stiff polyethylene catheters and 6) routine confirmatory X-ray or waveform monitoring before catheter use, if possible. We concluded that central venous catheterisations greatly facilitated the management of our patients. However, one must bear in mind that the use of such catheters is associated with problems which must be recognised early and promptly treated and, if possible, prevented with safe practice.
中心静脉导管在重症患者的护理中被广泛应用。本文回顾了我们在1994年8月至1995年8月期间,对需要重症监护的儿科患者使用中心静脉导管的经验。共对40例年龄均小于12岁的患者进行了57次置管操作。我们发现使用导管最常见的指征是营养支持(40%)。总体并发症发生率为58%。与导管相关的感染是最严重的问题,在所有置管操作中发生率为32%。凝固酶阴性金黄色葡萄球菌是最常分离出的病原体。维护问题影响了我们17根导管,其中9根堵塞。感染和堵塞的导管均被及时拔除。我们有3例穿孔和2例血栓形成。没有直接归因于导管使用的死亡病例。提出的建议包括:1)对工作人员进行教育并制定新的导管护理指南;2)使用细菌过滤器;3)对导管感染率进行仔细的前瞻性监测;4)当输注速度小于2 ml/h时进行肝素化;5)淘汰硬聚乙烯导管的使用;6)如果可能,在使用导管前进行常规的确认性X线检查或波形监测。我们得出结论,中心静脉置管极大地便利了我们对患者的管理。然而,必须牢记,使用此类导管会带来一些问题,必须尽早识别并及时治疗,并且如果可能的话,通过安全操作加以预防。
