静脉留置针成功穿刺的影响因素研究进展摘要静脉留置针是在医疗服务与救治中非常广泛使用的医用手段。这种注射手段一般被称作套管针，它是由针芯、外套管和其余的辅助塑料配置而成。在使用时，将整个套管针扎入静脉之中，当套管在静脉中固定好以后将针芯拔出，在整个静脉之中只剩下导管输送注射液，是目前新兴的一种较为方便的注射方式。与传统的针芯直接穿刺静脉的方法相比，留置针只用刺入静脉一次，可以有效的不伤害血管，在削弱患者“打针”的疼痛感方面有着良好的效果。目前这种手段被广泛使用在需要长期进行点滴的患者和一些体质较差者，在老人、婴儿等身上取得了良好的效果。静脉留置针使用对象广泛，在急诊方面必要情况下迅速注入药液或者输血的，也可以进行留置套管针的操作。一般而言，成功建立静脉留置针需要多次穿刺，这会加重患者的痛苦，造成不必要的伤害，并在将来限制血管的选择。本论文分析了静脉穿刺的操作步骤，研究在各种条件控制下静脉穿刺的不同情况。收集归纳对于静脉穿刺操作方法的各种影响参数和重点控制量，根据研究情况，归纳了该种操作手段的各种因子：静脉选择、部位选择和穿刺技术等。本研究的目的是降低临床上使用套管针的失败率，根据套管针和传统穿刺的比对，找到两者的相似和不同之处，对整个医学操作流程进行管理和控制，降低其余因子的影响，控制差异化方面。同时分析研究护士的个人发展，操作手感和患者的血管及个体的差异。关键词：静脉留置针影响因素ResearchProgressonInfluencingFactorsofsuccessfulpunctureofvenousindwellingneedleAbstractIntravenousindwellingneedleisawidelyusedmedicalmeansinmedicalserviceandtreatment.Thisinjectionmethod,commonlyknownasatrocar,consistsofaneedlecore,anexternaltrocar,andotherauxiliaryplastic.Inuse,thewholetrocarisinsertedintothevein,andtheneedlecoreispulledoutafterthetrocarisfixedinthevein,leavingonlythecatheterforinjectiondeliveryintheentirevein,whichisarelativelyconvenientinjectionmethodatpresent.Comparedwiththetraditionalmethodofneedlecoredirectpuncturetothevein,theindwellingneedleonlypiercedtheveinonce,whichcaneffectivelynotharmthebloodvessels,andhasagoodeffectinreducingthepainofthepatient"injection".Atpresent,thismethodiswidelyusedinpatientswhoneedtocarryoutadripforalongtimeandsomepeoplewithpoorphysique.Goodresultshavebeenachievedintheelderly,infantsandotherbodies.Intravenousindwellingneedlesarewidelyused,andcanalsobeusedforrapidinfusionofliquidmedicineorbloodtransfusioninemergencycases.Ingeneral,thesuccessfulestablishmentofanintravenousindwellingneedlerequiresmultiplepunctures,whichcanaggravatethepatient'spain,causeunnecessaryinjury,andlimitthechoiceofbloodvesselsinthefuture.Thispaperanalyzestheoperationstepsofvenipunctureandstudiesthedifferentsituationsofvenipunctureundervariouscontrolconditions.Theinfluencingparametersandkeycontrolquantityofvenipunctureoperationmethodwerecollectedandsummarized.Accordingtotheresearchsituation,thefactorsofvenipunctureoperationmethodweresummarized,suchasveinselection,siteselectionandpuncturetechnique.Thepurposeofthisstudyistoreducethefailurerateoftrocarinclinicaluse,findoutthesimilaritiesanddifferencesbetweentrocarandtraditionalpuncture,manageandcontroltheentiremedicaloperationprocess,reducetheinfluenceofotherfactors,andcontrolthedifferentiation.Atthesametime,thedifferencesofnurses'personaldevelopment,operationfeelandpatients'bloodvesselsandindividualswereanalyzedandstudied.Keywords:veinIndwellingneedleinfluencefacto目录引言................................................................1一、概述............................................................1（一）静脉留置针...
