改良医学机能实验中动脉插管的实验研究

目的：比较传统自制的动脉插管和使用直型留置针代替动脉插管在医学机能实验中应用的情况,找出一种便于学生操作、成功率高的动脉插管方法。方法：将40例实验动物随机分为A组和B组,分别用传统自制的动脉插管和用18G×29MM型号直型静脉留置针做动脉插管行颈总动脉插管术,并对2组插管方法的手术时间及成功率进行比较和评价。结果：用传统自制的动脉插管和用直型留置针做动脉插管2组比较,在手术时间和插管成功率上直型留置针做动脉插管方法明显高于传统的动脉插管方法。结论：直型留置针做动脉插管与传统自制的动脉插管相比具有简单、快速、准确、安全及成功率高等优点。用直型留置针代替传统动脉插管的最大优势是合理地解决了自制动脉插管口径大小不一、无固定点而易脱落等问题,值得推广。     

留置针在浅静脉输液中的使用方法与技巧

静脉留置针其操作简单,安全方便,在抢救危重病人、输注化疗药物和静脉营养等方面发挥了重要作用,减轻了反复静脉穿刺带给患者的痛苦,为患者提供了中长期的静脉治疗通道,又减轻了护士的护理工作量。现将静脉留置针在浅静脉输液中的使用方法与技巧介绍如下。     

静脉留置针患者的护理方法研究

目的:探究静脉留置针的应用及护理方法。方法:选取2017年1月～2018年3月收治的儿童患者100例,都使用静脉留置针的输液方式。将患者随机分为对照组和观察组,每组50人,对照组患者采用常规的基础性护理,观察组则使用综合护理,对两组患者护理临床效果进行观察分析。结果:两组患者接受护理后,观察组患者的并发症情况(药物外渗,管道堵塞,留置针脱出,皮下血肿)与使用基础护理的对照组比较,差异具有统计学意义(P<0.05)。结论:对静脉留置针患者使用综合护理,能够在规定时间内延长静脉留置针的使用时间,降低患者的并发症发生率。     

护理干预在静脉留置针使用的价值探究

静脉输液是临床上最重要的治疗、抢救措施,输液问题成为决定患者安全、护理工作满意度的主要因素,而输液工具的正确选择是保证输液安全和有效的重要一环。国家2014年新实施的《静脉治疗护理技术操作规范》,要求用静脉留置针代替钢针使用。但在实际临床工作中静脉留置针的接受率和使用率并不高,所以必须探讨有效的健康宣教方式。本研究通过加强护理干预提高留置针的使用率,有效减少并发症,提高护理工作的满意度。     

静脉留置针在儿科的使用特点及体会

随着医学技术的进步，静脉留置针在临床的应用越来越广泛，既减轻了患者痛苦，又为合理用药和紧急抢救带来了极大的方便，深受患儿家长的欢迎。由于小儿天生好动、自制力差等原因，造成留置针脱管、堵管、静脉炎、意外拔掉等现象增加。笔者所在医院2001年开始使用小儿浅静脉留置针，并针对在临床工作中遇到的问题，     

头皮静脉留置针在儿科输液中心使用中存在的问题分析

静脉留置针的应用是临床输液较好的方法,可以减轻婴幼儿因头皮针反复穿刺带来的痛苦,也减轻临床护士的工作量。该科自从2011年8月—2012年8月使用头皮静脉留置针的患儿为122例,针对年龄1个月～3岁,需要输液治疗3d以上、静脉穿刺难度大及危重患儿,并对在使用中存在的问题进行分析。

静脉留置针在手术麻醉中应用的体会

在手术麻醉过程中,有效的静脉输液输血是保证手术顺利进行的重要措施之一,保证静脉输液顺利进行是对麻醉手术病人护理工作的重点,近几年来,我科采用静脉留置针为病人进行输液输血,避免了手术过程中因不能有效地建立静脉通路或因病人体位变动,管理不当等原因造成液体补充不足,穿刺针位置移动,液体外漏等现象.也便于手术中用药和抢救,同时因留置针管腔大也可使药物在短时间内进入体内达到预期效果,及时补充液体量,及时纠正各种生理功能失调及液体不足情况,确保麻醉手术病人的安全.     

引针在小儿静脉留置针中应用的效果分析

静脉输液是治疗耳科疾病的常用方法,但儿科静脉穿刺一直是儿科护理工作中的一大难点[1]传统的金属头皮针,不能有效地保证补液用药的需要,直接影响正常工作的进行。反复多次的静脉穿刺,既造成患儿的痛苦,又易使浅表静脉受到破坏,使以后的静脉穿刺更加困难,同时也增加了护士的工作量,静脉留置针的普及应用有效地解决了这一问题。[2]在解决这个问题的同时,为了使患儿痛苦降到最低,使留置针的使用寿命更长,更好地体现其价值,我科使用了在留置针上接引针(引针就是在2.5ml或5ml的注射器上去掉针头换上头皮针,用生理盐水抽吸,并排尽空气)的方法对患者进行穿刺,结果大大提高了穿刺率,有效地提高了留置针的寿命。     

一体式负压静脉留置针在泌尿外科的临床应用研究

目的：对一体式负压静脉留置针在泌尿外科中的临床应用效果展开分析。方法：选取天津市第三中心医院泌尿外科于2020年3月～2021年3月收治的108例住院患者,随机分为观察组和对照组,各54例;对照组采用静脉分体式留置针,观察组采用一体式负压静脉留置针,比较两组的应用效果。结果：经治疗,观察组的留置时间为（79.12±10.51）h,高于对照组的（68.52±14.38）h(P<0.05);观察组的一次穿刺成功率为98.15%,高于对照组的88.89%(P>0.05);观察组的并发症发生率为3.70%,低于对照组的14.81%(P>0.05)。观察组的满意度为96.30%;高于对照组的87.04%(P<0.05)。结论：一体式负压静脉留置针具有更好的防菌、防感染效果,降低并发症发生率。     

Characteristics of injection drug users who utilize tuberculosis services at sites of the baltimore city needle exchange program

Objective To describe characteristics of needle-exchange program (NEP) participants who utilized tuberculosis services from an NEP site. Methods Between June 1998 and May 1999, tuberculosis services were advertised and offered to Baltimore, Maryland, NEP participants. Demographic and tuberculosis-specific data were collected on participants who self-selected into services. Analyses were based on being tuberculin skin tested, returning for a skin test reading, and testing tuberculin positive. Results Among 691 contacts with NEP participants, this service performed 296 tuberculin tests, with an 84% return rate for skin test reading. Participants were 32% female, 87% African American, and 11% employed. Higher frequency of NEP visits was positively associated with requesting tuberculosis services and returning for skin test reading. Among those who returned for skin test reading, longer smoking duration and problems getting food in the past year due to a lack of money were associated with a positive test. Conclusions Utilization of a tuberculosis service and high return rates can be achieved among NEP participants without formal recruitment strategies. Frequent exchange appears to facilitate return visits for NEP-based tuberculosis screening, which may imply accessibility for frequent exchangers. More extensive health services at sites of the Baltimore NEP appear to be warranted, with particular attention paid to effectiveness for frequent exchangers.     

Crystal methamphetamine use associated with non-fatal overdose among a cohort of injection drug users in Vancouver

OBJECTIVES: To evaluate the prevalence and correlates of non-fatal overdose among a polysubstance-using cohort of injection drug users (IDU) in Vancouver. STUDY DESIGN/METHODS: We evaluated factors associated with non-fatal overdose among participants enrolled in the Vancouver Injection Drug Users Study (VIDUS) using univariate statistics. Self-reports of the awareness of drugs taken and drug potency, polysubstance use, and assistance received at the time of non-fatal overdose were also recorded. RESULTS: From 1 December 2003 to 1 June 2005, 551 participants who were active injectors were followed. In total, 37 (6.7%) individuals reported experiencing a non-fatal overdose in the previous 6 months. Factors positively associated with non-fatal overdose included public injecting (odds ratio (OR)=4.74, 95% confidence interval (CI) 2.35-9.37, P<0.001), crystal methamphetamine use (OR=4.11) and injection (OR=3.63), morphine injection (OR=3.55), non-injection opiate use (OR=3.30), frequent heroin injection (OR=2.28) and sex trade work (OR=2.12). Factors negatively associated with non-fatal overdose included participation in methadone maintenance therapy (OR=0.31) and injecting alone (OR=0.36). Sixty-two percent of individuals were unaware of drug potency, 64.9% of IDU were taking other drugs at the time of overdosing, with crack being the main drug (37.0%). Fifty-four percent were assisted by ambulance personnel, 56.8% were taken to accident and emergency or hospital, 38.1% left accident and emergency or hospital before being released, and 35.1% were given Naloxone. CONCLUSION: Structural interventions are needed that seek to modify the social and contextual risks for overdose, increased access to treatment programmes, and trials of novel interventions for crystal methamphetamine users.
