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。
