ObjectiveTo investigate the application value of the intravenous indwelling needle in radionuclide imaging examination. MethodsA total of 120 patients underwent single photon emission computed tomography for bone and kidney dynamic imaging between October 2012 and April 2013 were randomly divided into group injected by venous indwelling needle (observagtion group) and group injected by traditional steel needle (control group), with 60 cases in each. We calculated the one-time success rate of venipuncture, the leakage rate of intravenous injection, residual radioactive dosage within the syringe and average exposure time of medical staff to radionuclide in the two groups of patients. ResultsThe one-time success rate of venipuncture in observation group was similar to that in the control group (P > 0.05). During the injection, no leakage was found in observation group, while 4 leakage in 37 patients underwent bone imaging and 3 leakage in 23 patients underwent kidney dynamic imaging in the control group were found; there was no significant difference between the two groups (P > 0.05). The residual radioactive dosage within the syringe in observation group was lower than that in the control group, and the exposure time of medical staff to radionuclide in observation group was also lower than that in the control group (P < 0.01). ConclusionsIntravenous indwelling needle for venous puncture can avoid leakage of radioactive imaging agent, reduce the residual radiological dosage within the syrings, increase the one-time puncture success rate and imaging resolution of dynamic scan, and improve the diagnostic accuracy and work efficiency effectively. Besides, the intravenous indwelling needle technique can reduce average exposure time of medical staff to radionuclide, acheaving the goal of optimized protection.
目的:观察艾灸联合芦荟、红花、当归酒精提取液治疗输液并发静脉炎的临床疗效。方法:将60例静脉炎患者随机分为两组,观察组采用艾灸联合芦荟、红花、当归酒精提取液治疗,对照组采用50%硫酸镁治疗,并进行疗效对比。结果: 观察组痊愈22例、显效6例、有效2例、无效0例,有效率100%;对照组痊愈13例、显效8例、有效3例、无效6例,有效率80%;两组相比差异有统计学意义(Plt;0005)。结论:艾灸联合芦荟、红花、当归酒精提取液具有活血化瘀、散结止痛、抗炎解毒、促进损伤组织细胞修复作用。
目的 探讨静脉留置针封管用肝素诱导的血小板减少症（HIT）的临床特点。 方法 分析2010年1月－2011年12月，在1 215例静脉留置针肝素封管患者中发生的14例HIT患者的临床表现，血小板（PLT）、HIT抗体的变化，氯吡格雷、阿加曲班、地塞米松等治疗的结果。 结果 1 215例患者中：发生HIT 14例，发生率1.15%；HIT并血栓形成综合征4例，发生率0.33%。14例HIT患者中：经典型12例，占85.7%。出血7例，发生率50.0%，其中1级、2级出血发生率分别为42.9%（6/14）、7.1%（1/14），分别占出血的85.7%（6/7）、14.3%（1/7）。血栓形成4例，发生率28.6%，其中静脉血栓3例，占血栓形成的75.0%。14例均发生于肝素封管后第1～14天，其中第6～7天8例，占57.1%。PLT降低到最低值的时间为肝素封管后2～10 d内，其中2～5 d内13例，占92.9%。PLT降低的最低值为（1.81～101）×109/L，其中PLT（20～70）×109/L12例，占85.7%；PLT降至最低时下降的比值为51.1%～90.1%，其中50%～80%10例、占71.4%。1例至28 d死亡时血小板没有恢复至肝素封管前水平，其余13例患者PLT减少持续时间5～13 d，其中5～10 d 10例，占76.9%。14例（100%）HIT患者HIT抗体阳性，其中13例（92.9%）在PLT开始减少时即阳性，1例在PLT减少2周后呈阳性。14例HIT患者中12例（85.8%）痊愈，1例（7.1%）脑血栓后遗症，1例（7.1%）死于急性肺栓塞。 结论 静脉留置针封管用肝素可导致HIT，PLT减少及血栓、HIT抗体是诊断的可靠依据。及时停用肝素，必要时抗凝、抗PLT、类固醇激素治疗效果好，部分患者进展快，死亡率高。
目的：通过经外周静脉穿刺中心静脉置管（PICC）或锁骨下静脉置管与前臂静脉留置针在血液病患者并发深部真菌感染时应用两性霉素B中的比较，探讨如何减少患者静脉炎及并发症发生率和再次静脉穿刺的发生率，从而提高患者生活质量。方法：80例血液病患者分为两组，40例PICC置管或锁骨下静脉置管组为A组，40例前臂静脉留置针为B组，记录静脉炎、疼痛发生情况、留置时间。结果：A组留置时间30～68天，B组留置时间1～5天；A组静脉炎率5%，B组静脉炎率45%；A组疼痛率5%，B组疼痛率35%；结论：在血液病患者并发深部真菌感染时应用两性霉素B治疗中，选用PICC置管或锁骨下静脉置管效果明显优于前臂静脉留置针，值得临床推广。
