目的比较超声引导下18G粗针与21G细针脾穿刺活检的安全性和有效性。方法53例行超声引导下脾穿刺活检的患者,局灶性病变35例,弥漫性病变18例。18G粗针组35例应用组织切割针配以自动活检枪;21G细针组18例应用手动活检针。结果46例明确了诊断,7例假阴性,准确率86.8%,2组比较进针次数和诊断准确率均有显著差异(P=0.017,P=0.037);1例并发出血,2组比较并发症的发生率没有统计学差异。结论18G针和21G针行超声引导下经皮脾穿刺活检均安全。18G粗针活检能够获得较多而完整的组织条,诊断的准确率较高,是获得病理诊断的有效方法。  相似文献

目的探讨INTIMA封闭式留置针替代普通输液针进行临床输液治疗的应用效果,以利推广使用.方法50例患者为观察组用INTIMA封闭式留置针进行静脉输液,70例患者为对照组用普通输液针进行静脉输液治疗,对两种输液方法的穿刺次数和液体渗漏等情况进行比较.结果两组输液方法的穿刺次数经t检验,P<0.01,差异有高度显著意义;对照组的渗漏率达62.86%,观察组的渗漏率为16.∞%,经卡方检验,P<0.01,两组差异有高度显著性意义.结论以INTIMA封闭式留置针替代普通输液针,其操作简便,成功率高,副作用小,减少静脉穿刺次数,延长每次静脉穿刺的间隔时间,有效提高护理工作效率,应在临床上广泛推广应用.  相似文献

木针介绍     
木针为作者1992年初创制的一种无创痛新型针具。该针由木材做成,有两种针型,四种针头。本文介绍了木针的针型、规格、持针方法、用针方式、用针方向、行针手法、刺激强度、施术时间、疗程安排等。临床试用表明,木针既能单独治疗不少病症,也能配合其它疗法综合施治;既能用于治疗,也能用于保健,除具有毫针和指针的共同优点外,木针较之毫针无损伤、无创痛,易为人们所接受;较之指针更便于准确取穴和持久操作。木针易学好用,除针灸医生外,还适合个人和家庭在针灸医生指导下进行自我或相互治疗、康复或保健。  相似文献

目的:探讨INTIMA封闭式留置针替代普通输液针进行临床输液治疗的应用效果,以利推广使用。方法:50例患者为观察组用INTIMA封闭式留置针进行静脉输液,70例患者为对照组用普通输液针进行静脉输液治疗,对两种输液方法的穿刺次数和液体渗漏等情况进行比较。结果:两组输注方法的穿刺次数经t检验,P<0.01,差异有高度显著意义,对照组的渗漏率达62.86%,观察组的渗漏率为16.00%,经卡方检验,P<0.01,两组差异有高度显著性意义。结论:以INTIMA封闭式留置针替代普通输液针,其操作简便,成功率高,副作用小,减少静脉穿刺次数,延长每次静脉穿刺的间隔时间,有效提高护理工作效率,应在临床上广泛推广应用。  相似文献

Conventional mediastinoscopy has a small but definite morbidity and mortality. Our continuing study was done to determine whether needle aspiration during mediastinoscopy is a safe and reliable procedure. In 14 consecutive patients having mediastinoscopy, needle aspiration biopsy was also done. There was a 100% correlation between diagnosis made by needle cytology and the final diagnosis, with neither false-positive nor false-negative results. This correlation was only 75% in the forceps biopsy group. In 90% of the cases, the cytopathologist correctly identified the final cell type. There were no complications, even in cases of superior vena caval (SVC) obstructions. The distinct advantages of the technique include high specificity, better tissue sampling, immediate availability of results, reduced morbidity, expanded indications in SVC syndromes, and higher yield than conventional punch biopsies.  相似文献

Needle emboli to lung following intravenous drug abuse   总被引:1,自引:0,他引:1  
Presented is the case of a 36-year-old man using central venous sites for injection of street drugs. X-ray study revealed numerous retained subcutaneous needles as well as a needle that had embolized to the lung periphery. This represents, to the best of our knowledge, a previously unreported complication of central venous injection of street drugs.  相似文献
