目的通过静脉长期血透导管外固定袋囊的使用,达到利用该方法减轻导管对隧道口物理刺激及改善全身微炎症状况的目的。方法带雌雄粘贴片的纯棉布制作袋囊,用于在透析间期将长期导管固定在患者内衣的内面舒适位置,观察使用前后患者隧道口的自觉症状、体征,血常规中白细胞计数(WBC)、中性粒细胞百分比(N%)、血C反应蛋白(CRP)等指标变化。结果使用长期血透导管外固定袋囊三个月后,患者隧道口瘙痒、疼痛情况明显减轻(有效率90%);红肿、渗液明显好转(有效率85.7%);虽然血WBC变化不明显,但N%有所下降(P≈0.05),CRP显著下降(P<0.05)。结论静脉长期血透导管外固定袋囊使用方便,经济、有效,是值得临床进一步推广应用的固定长期血透导管的新方法。
Objective To achieve the goal of using this method to reduce the physical stimulation of the tunnel to the tunnel port and to improve the systemic micro-inflammatory status through the use of long-term intravenous venous catheterization. Methods Pure cotton cloth with male and female adhesive tapes was made into bags, which were used to fix the long-term catheters to the inner comfortable position of patients’ lingeries during the dialysis interval. The symptoms and signs of tunnel entrance and the white blood cell count ), Neutrophil percentage (N%), blood C-reactive protein (CRP) and other indicators. Results After three months of long-term hemodialysis catheter external fixator bag, the patients suffered from itching and pain in the tunnel mouth (the effective rate was 90%). The swelling and exudate were obviously improved (effective rate was 85.7%). Although the change of blood WBC was not obvious , But N% decreased (P ≈0.05), CRP decreased significantly (P <0.05). Conclusions Venous long-term hemodialysis catheter external fixation bag is easy to use, economical and effective, and is a new method of fixed long-term hemodialysis catheter which is worth further clinical application.
