Thirty cadaveric femurs were randomly allocated into five groups, each with 6 femurs. An osteotomy was made (Pauwels angle 70°) in the middle of the femoral neck. Then each group was fixed using one of these methods:①Dynamic Hip Screw ;②Three 4mm Steinn Pins that placed in accordance with the compressive trabeculae and clingy to the femoral calcar ;③One compressive screw;④Low angle fixation of external fixator;⑤High angle fixation of external fixator.

Sims and Saleh performed pin site care daily beginning 48 hours after the operation. In their study, they applied Orthox monolateral xators (Orthox Srl, Bussolengo–Verona, Italy)(58.4%), circular xators (19.7%), and the Shefeld Hybrid System (21.9%). Massage was used to release skin adhered to the pin. A cotton swab with normal saline or cooled boiled water was used to clean the pin site. Another cotton swab was then used to dry the pin site. Dressings were only applied if there was any exudate. Bathing with the leg submerged in water was discouraged. They found that 29% of the xators had noinfection (grade 0) according to the grading system of Saleh and Scott (Table 5). The remaining 71% of xators had an infection of one or more different grades. There were no grade 6 infections. They concluded that xators located on the femurhad the highest infection rate and that incidence of infection was 2.5 times greater for femoral xators in which corrections were performed (62.3%) than in those without corrections (24.5%). These observations, however, were based on half-pin care. We did not use half-pins or Schanz screws in any of our treatment groups.

Sims and Saleh在手术后48小时开始进行没人针孔护理，在他们的研究中，他们应用Orthox单臂外固定架(Orthox Srl， Bussolengo–Verona， Italy)（58.4%），环形外固定架（19.7%），Shefeld组合式外固定架（21.9%），按摩放松附着于钢针上的皮肤，蘸有生理盐水或凉开水的棉拭子用于清理针孔，另外一个棉拭子用于蘸干针孔，只有局部出现渗出是才应用敷料，阻止患者进行将带有外固定架的肢体浸入水中的洗浴方式，他们按照Saleh and Scott的标准发现29%的外固定架没有感染（0级），剩余71%外固定架有1个或者多个级别的感染，他们没有6级感染，他们得出结论：位于股骨的外固定架有最高的感染几率，而且实施矫形患者的感染发生率（62.3%）是不进行矫形患者感染发生率（24.5%）的2.5倍，但是，这些观察是基于半钉护理，在我们的任何一个治疗组中都没有应用半钉和Schanz螺钉。

The result of immobilization showed that hydrophile membranes were more advantageous than hydrophobe ones to act as immobilization carrier. Crosslinking organophosphorus hydrolase by glutaraldehyde on polyethersulfone membrane is a simple and practical immobilization method. An appropriate amount of bovine serum albumin and crosslinker is necessary to get a good result of immobilization. In the biodegradation of methyl-parathion through enzyme membrane reactor, the effect of immobilized enzyme amount, flow rate of peristaltic pump, pH of the feed, and the methyl-parathion concentration on biodegradation rate was studied. It was shown that the biodegradation rate increased with immobilized enzyme amount and substrate concentration. Biodegradation rate didn't increase when the folw rate of the peristaltic pump was larger than 7 ml/min.

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。
