It is thought that the advantages of this method are:①dialyze completely beause of the volume of blood flow up to 200 to 300ml per minute ,②affect cardiovascular system alighily beause of blood flow form vien to vein during the pocess of hemodialysis ,③keep patients moving freely,and ④indwell catheter several weeks.

作者认为锁骨下静脉双胜留置导管血液透析的优点很多，首先，血流量可达200～300ml／min，能保证充分透析；另一方面透析时血液循环是静脉到静脉，对心血管系统影响小；该部位插管病人活动不受限，且导管留置时间可长达数周，所以不仅可作和临时性血透通路，也可作为长期维持性血液透析的血透通路。

80 patients with pneumocardial disease were divided randomly, with tube sealing on trochar with heparin dilution liquid and sodium chloride, respectively. The detain time, operation time, and material cost were compared and analyzed.

通过对80例使用浅静脉留置针的肺心病患者，采用随机分组对照方法进行比较，分别用肝素稀释液与生理盐水对留置针进行封管，从留置时间、操作时间、材料成本方面进行比较和分析。

Conclusion1 Critically ill patients with indwelling catheters were of the high positive rate of microorganisms,and microorganism spectrum was of special properties;BF formed mainly inside the catheter,the occurrence rate of BF inside the catheter was high and the formation time was short;Changes on catheters and the result of microorganisms was positively correlated with the BF formation.2 Indwelling catheter time was the independent risk factors for the BF formatiom, while age、APACHEⅡscore、sex、urine sugar and the types of antibiotic usage were the potential risk factors for the BF formation;Nurses should perfect the catheter measures for critical ill patients,emphasis on the assessment of risk factors of BF formation,and implement special care in high-risk patients.3 In the early stage of BF formation,irrigation could play the role of eradicative BF effectively;While later,it couldn't,but it can delay the speed of BF formation and maturation;In the choice of washing methods,injection type washing method is superior to infusion.

结论1重危患者留置尿管微生物培养阳性率高，且微生物菌谱具有特殊性；重危患者尿管表面BF主要在尿管内壁形成；内壁BF的发生率高，形成时间短；肉眼观察尿管表面改变情况以及微生物鉴定结果与BF形成呈正相关。2尿管留置时间是重危患者留置尿管表面BF形成的独立危险因素；年龄、APAcHEⅡ评分、性别、尿糖定性以及抗生素使用种类是其可能的危险因素；护理过程中应完善重危患者尿管护理措施，注重对BF危险因素的评估，并对高危患者实施重点护理。3 BF形成早期，冲洗能发挥较好的清除作用；BF形成后期，冲洗无法彻底清除尿管表面BF，但冲洗能延缓BF形成与成熟的速度；在冲洗方式的选择上，注洗式冲洗法对尿管BF的清除效果优于输注式冲洗法。

Needle taking place is commonly used the rescue that changes cure and danger to weigh a patient at patient of children, tumour, in infusion, because secure not firm outside can bringing about syringe needle slippery haemorrhage to be in charge of, cause local strut, aching, serious person can send infiltration of the certain pharmaceuticals that change cure to cause subcutaneous tissue hypodermically necrotic or the liquid cannot be defeated in time note and illness of incur loss through delay, new puncture increases the patient's anguish not only, also increased economic burden to also can be affected at the same time to the patient nurse working quality, the course relapses clinical experiment, my division adopts vein to accept the annular and fixed method of buy needle, obtained better result, introduce as follows now. 1 method is taken fixed stick (needle taking place is deployed) together, the disinfection that wide 10cm controls wraps cloth, two paragraphs of end are seamed on after sticking glue to buckle vein to leave buy needle puncture to succeed, convention is secured with adhesive plaster, next the ground degree of tightness will take stalk of handle of buy pinhead, needle, needle to be in firmly aptly fixed and fixed stick , next annular in blood-vessel twine stick on stick buckle. 2 experience apply this method to secure vein to left buy needle method to reduce the patient's anguish, reduced cost, provided mobile space for the patient, also avoid heparin cap prolapse, still facilitate observation puncture is nodded, do not affect hematic use, gauze pad can alleviate heparin cap is oppressive and unwell, reduce infusion pollution.

概要： 留置针常用于小儿、肿瘤患者化疗及危重患者的抢救，在输液中，由于固定不牢可导致针头滑出血管外，引起局部肿胀，疼痛，严重者可致某些化疗药物渗入皮下造成皮下组织坏死或液体不能及时输注而延误病情，重新穿刺不仅增加病人的痛苦，也给病人增加了经济负担同时也会影响护理工作质量，经过反复临床实验，我科采取静脉留置针的环形固定方法，取得了较好的效果，现介绍如下。1方法取固定贴一块，宽10cm左右的消毒包布，两段端缝上粘胶扣静脉留置针穿刺成功后，常规用胶布固定，然后将根据松紧适宜将留置针头、针柄、针梗处牢牢固定固定贴，然后在血管中环形缠绕粘上粘扣。2心得应用此方法固定静脉留置针方法减少了患者的痛苦，降低了费用，为患者提供了活动的空间，也避免肝素帽脱垂，还便于观察穿刺点，不影响血运，纱布衬垫可缓解肝素帽压迫不适，减少输液污染。
