建立可靠、快速的血管通路是急、慢性肾功能衰竭,急性药物及毒物中毒等患者及时进行血液透析治疗的根本保障。选择桡动脉或足背动脉直接穿刺建立单一紧急血透通路,在一般医院应用仍较为广泛,但存在血流量时有不足弊病,使透析效果受... 建立可靠、快速的血管通路是急、慢性肾功能衰竭,急性药物及毒物中毒等患者及时进行血液透析治疗的根本保障。选择桡动脉或足背动脉直接穿刺建立单一紧急血透通路,在一般医院应用仍较为广泛,但存在血流量时有不足弊病,使透析效果受到影响。本文总结了我院1992-02~1999-02对28例患者进行161次单一桡、足背动脉穿刺遇血流量不足时,采用再建一条血管通路的方法来保证血流量,取得了满意效果。现将应用体会报告如下。 1 临床资料 1.1 一般资料 本组病例28例,男13例,女15例,年龄18~76岁,平均年龄47.6岁。其中急性肾衰少尿期5例,各种中毒6例,急性肺水肿并发左心衰4例,高血钾3例,维持性透析内瘘成熟前需做紧急透析4例,长期透析数年后内瘘阻塞2例,建立内瘘困难3例,腹膜透析并发腹膜炎致导管阻塞临时改血透1例。 1.2 透析设备 透析机为德国(Fresenius A2008C、D;Fresenius Medical Care 4008B)型,透析器采用1.2m2血肪膜(Hemophan)或1.3m2聚砜膜(Hemeflow F6),一次性输血管,碳酸盐透析液,透析液流量2500ml/min。血流量要求150~300ml/min[1〕。 2 操作方法 2.1 常规消毒皮肤,选体表静脉作回路,采用G16动静脉内瘘针,触足背或桡动脉搏动最明显处下方1cm与皮肤呈15~25°进针,见搏动性回血后即固定针头,连接动脉血路管。如遇血流量不足,经调整针头角度和方向,血流量仍不能提高时,在不放弃已建立的血管通路和血流量的基础上,即用一次性输血器,管内注满0.1%肝素盐水,夹闭排气管道,再将输血器上端(粗针头端)针头插在血泵前的动脉血路管的侧管上,输血器下端(头皮针端)接处连接16G内瘘穿刺针(也可采用三通管将两路管道连接于血路管动脉前端)。关闭输血管,另选一侧桡动脉或足背动脉及其它浅动脉,用同样的操作方法行穿刺,见回血后即打开输血管开关,使两条血管通路的血液汇集相加同时进入体外循环,达到透析所需要的血流量。 2.2 透析结束后,先回一次性输血器侧血液,拔针后即刻抬高管路,将血流量减至100ml/min,利用空气将输血管内的血液驱回动脉血路管后关闭输血管,另一侧按常规回血程序进行操作。 展开更多

Objective To investigate the efficacy of continuous renal replacement therapy(CRRT)versus intermittent hemodialysis(IHD)in patients with severe acute renal failure(ARF).Methods One hundred and ninety -three severe ARF patients who received renal support between December 1978 and December 1998 were involved in this study.Of them,101(52.3%)were treated with CRRT(CRRT group),and 92(47.7%)with IHD(IHD group).Results Sixty(59.4%)patients in the CRRT group got through the acute phase of disease and 41 (40.6%)patients did not survive while in the IHD group 59(64.1%)patients survived and 33(35.9%)patients did not.No significant difference in survival rate was found between the two groups.24 of 64 patients(37.5%)in the CRRT group with multiple organ dysfunction syndrome(MODS)survived,while in the IHD group,8 out of 44(27.3%)survived,their survival rate was much lower than that in the CRRT group.Patients in CRRT group were more severely iii,as manifested by lower mean arterial pressure,higher APACHE Ⅱ score,more dysfunctioned organs and requiring mechanical ventilation and vasopressor support as compared with patients in the IHD group,CRRT was found to improve hemodynamic stability with a better fluid balance and control of biochemical status,increased nutritional intake and a shorter duration of acute renal failure(P < 0.05).Conclusion CRRT perhaps may be the best choice in the treatment of severe ARF patients,for it can offer several distinct advantages compared to IHD.These may contribute to improving the survival rate of ARF patients,particularly those that are critically ill patients. 展开更多
