摘要:

文题释义:
带隧道带涤纶套导管(tunneled cuffed catheter,TCC):俗称长期导管,是一种主要用于血液净化带有涤纶套的中心静脉导管。置管时需要建立皮下隧道,将涤纶套埋入皮下与皮下组织粘连愈合,起到固定置管和防止细菌从皮肤开口侵入的作用。
肝素涂层:在人工医学材料表面通过物理或化学方法涂覆肝素,从而改善人工材料的血液、生物相容性,减轻术后的全身炎性反应。

背景:Palindrome H 肝素涂层带隧道带涤纶套导管(简称Palindrome H 肝素涂层导管)有望降低导管相关感染率和减少导管功能不良的发生,目前缺乏该导管对凝血系统影响的研究。

目的:评估Palindrome H 肝素涂层导管的对血液透析患者凝血系统的影响。

方法:选取2014年1月至2016年6月在佛山市第一人民医院血液净化中心需维持性血液透析,而无法建立内瘘的患者,分为Palindrome H 肝素涂层导管组和非肝素涂层Palindrome导管组2组,分别置管。所有患者每3个月检测血小板计数、凝血酶原时间、国际标准化比值(INR)、活化部分凝血活酶时间、凝血酶时间、纤维蛋白原降解产物等指标,进行组间对比。试验方案通过了广东省佛山市第一人民医院医学伦理委员会的讨论审核,批准号:L[2014]第5号。

结果与结论:最终纳入患者60例(Palindrome H 肝素涂层导管组28例,Palindrome导管组32例),进行了为期30个月的随访,结果数据为置管后第0,3,6,9,12,15,18,21,24,27,30个月检测的平均值。结果显示两组患者的血小板计数、凝血酶原时间、国际标准化比值(INR)、活化部分凝血活酶时间、凝血酶时间、纤维蛋白原降解产物等指标比较均无统计学差异(P > 0.05),没有实验室检查表明发生了肝素诱导的血小板减少症。说明在临床应用中,Palindrome H肝素涂层导管与非肝素涂层Palindrome导管相比较,对患者凝血系统无明显影响。

Abstract:

BACKGROUND: The new type Palindrome H-heparin-coated dialysis catheter is supposed to reduce the incidence of catheter-related infection and catheter dysfunction. However, the effect of this new type catheter on the systemic coagulation function is little reported.

OBJECTIVE: To evaluate the effects of the new type heparin-coated dialysis catheter of Palindrome H on the systemic coagulation function in hemodialysis patients.

METHODS: Patients who underwent maintenance hemodialysis and could not establish internal fistula at Blood Purification Center of the First People's Hospital of Foshan from January 2014 to June 2016 were enrolled. All participants were divided into Palindrome H heparin-coated and Permcath noncoated groups depending on the catheter type. The blood platelet count, prothrombin time, international normalized ratio, activated partial thromboplastin time, thrombin time and fibrinogen degradation products were detected and compared between two groups. The study was approved by the Ethics Committee of the First People’s Hospital of Foshan, approval No. L[2014]5.

RESULTS AND CONCLUSION: Sixty patients were involved in the study (28 patients used the Palindrome H heparin-coated catheter and 32 patients used Permcath noncoated catheter). All patients were followed up for 30 months. The final measurement outcome was the average value at 0, 3, 6, 9, 12, 15, 18, 21, 24, 27 and 30 months after surgery. No significant difference was found in the blood platelet count, prothrombin time, international normalized ratio, activated partial thromboplastin time, thrombin time or fibrinogen degradation products between two groups (P > 0.05). No heparin induced thrombocytopenia was observed in all participants. Therefore, in clinical practice, the new type Palindrome H-heparin-coated dialysis catheters makes no effect on the systemic coagulation function compared with noncoated catheter.
