摘要目的 探讨植入性中心静脉通道装置(Port)在肿瘤患儿中应用的疗效.方法 通过对176例安装化疗泵的恶性肿瘤患儿的观察,分析其置管的途径、导管放置的长度、并发症发生的原因及处理.结果本组176例患儿经颈外静脉切开123例,锁骨下静脉穿刺插管38例,经颈内静脉穿刺插管15例.导管应用期间共有46例出现相应的并发症,占26.1%.其中导管相关性感染占15.3%,导管的阻塞占16.8%.结论 化疗泵在肿瘤患儿中有良好的应用价值.导管相关性感染是化疗泵使用过程中最常见的并发症,导管的阻塞多因放置的位置或者长度不当而引起.操作医师的专业化对减少并发症的发生具有相当重要的作用.

abstractsObjective To analyze the effect of central venous access devices (Port) implantation for children with cancer. Methods The clinical data of the route and length of catheter implantation, and the causes and management of associated complications in 176 children with cancer implanted with central venous catheter were retrospectively analyzed. Results Of all the cases, 123 catheters were in-troduced through external jugular venotomy, 38 were through subclavian vein puncture and 15 were through the internal jugular vein puncture. Associated complications were noted in 46 cases (26. 1%) during the treatment of Port, in which 27 complicated with catheter related infection and 19 with cathe-ter obstruction. Conclusions Port is safe and effective for children with cancer. Catheter-related infec-tion is one of the most common complications. The inadequate position and insufficient length of cathe-ter implantation may cause catheter obstruction. With experience accumulation and specialization train-ing for surgeons, the incidence of complications of central venous catheter implantation may be re-duced.
