化疗是临床肿瘤治疗的重要手段,静脉用药是其主要途径。由于化疗是多个疗程长时间的反复用药,要进行多次反复的静脉穿刺,而且化疗药物本身对血管有损害,因此常可致静脉发生无菌性炎症,严重者出现血管闭塞不通,给治疗用药带来困难,因此,合理选用血管,不断提高穿刺技术和妥善保护好血管尤为重要。自1994年起,我们在临床工作中采取综合方法保护静脉,使病人血管的连续使用时间和次数明显提高。现将体会总结如下:1.建立系统的静脉使用计划 一般由四肢远端开始,尽量避开指趾静脉,因为这些部位血管较细,且神经末梢分布广,对疼痛敏感,患者不愿接受。同时应双侧交替使用,糖尿病宜少用下肢静脉。 Chemotherapy is an important method for clinical cancer treatment. Intravenous administration is its main approach. Since chemotherapy is a repeated treatment with multiple courses of treatment for a long time, multiple repeated intravenous punctures are required, and the chemotherapy drugs themselves have damage to blood vessels. Therefore, aseptic inflammation often occurs in veins, and vascular occlusion in severe cases occurs. It is difficult to use drugs. Therefore, it is particularly important to use blood vessels rationally, continuously improve puncture techniques and properly protect blood vessels. Since 1994, we have adopted a comprehensive approach to protect veins in our clinical work, which has significantly increased the time and frequency of continuous use of blood vessels in patients. The experience is summarized as follows: 1. Establish a system of intravenous use plan Generally from the distal extremities, as far as possible to avoid the finger vein, because these parts of the blood vessels are thin, and nerve endings are widely distributed, sensitive to pain, patients are reluctant to accept. At the same time should be used alternately on both sides, diabetes should be less use of lower extremity veins.
