目的 调查在院前急救中医患双方对留置针使用的满意度，并就留置针在急救中应用的合理性进行研究。 方法 将我院急诊科2011年6月－8月院前急救的患者，按出诊顺序分为两组，观察组患者使用留置针穿刺建立静脉通道，对照组则采用一次性静脉输液针，并调查患者或亲属、穿刺操作护士就两种穿刺方法的满意度。 结果 观察组留置针一次穿刺成功者达198例（94.29%），对照组一次穿刺成功者为206例（88.79%），两组比较差异有统计学意义（P＜0.05）；护士对留置针使用满意度明显高于一次性静脉输液针；患者及家属对留置针在保持静脉通道通畅、输液肢体舒适的满意度较一次性静脉输液针高。 结论 静脉留置针在院前急救中能提高医患双方的满意度，值得推广使用。
Objective To evaluate the effects of peripheral venous remaining needle sealing with heparin vs. saline in China. Methods A comprehensive, systematic bibliographic search of medical literature from databases of CNKI (1994 to December, 2009) and Wanfang (1990 to December, 2009) was conducted to identify randomized controlled trials (RCTs) related to catheter sealing with saline vs. heparin. The remaining time of venous needle, the incidence of phlebitis and the catheter blockage were compared, and the quality of RCTs was assessed and meta-analyses were conducted by RevMan 5.0 software. Results Nine RCTs involving 1 770 patients were included. The results of meta-analyses showed that: a) There was a significant difference between heparin sealing and saline sealing in catheter blockage (OR=0.44, 95%CI 0.32 to 0.62, Plt;0.05). The heparin sealing was much better to prevent catheter blockage; b) There was no significant difference between saline sealing and heparin sealing in the incidence of phlebitis (OR=1.26, 95%CI 0.64 to 2.50, Pgt;0.05); and c) The average remaining time of venous catheter between saline sealing and heparin sealing had significant difference (WMD=0.24, 95%CI 0.04 to 0.43, Plt;0.05). Heparin sealing had better effect than saline sealing. Conclusion The meta-analyses of current medical literature in China show that heparin sealing can reduce the incidence of catheter blockage and prolong the remaining time of catheter, although there is no significant effect in the aspect of the incidence of phlebitis.
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。
ObjectiveTo reduce patients' adverse events caused by needle indwelling through quality control circle (QCC) activities, in order to ensure the effectiveness and safety of intravenous fluids. MethodsGuided by the QCC theory, we set up QCC, selected the topic related to reduction of patients' adverse events caused by needle indwelling, and worked out the plans from September 2012 to April 2013. Then, we adopted Plan-Do-Check-Act (PDCA) cycle method to set up goals, formulate measures, and inspect and improve the results. ResultsThe incidence of needle-related adverse events reduced from 44.8% to 9.8% by implementation of quality circle activities. There was a significant statistical difference between the two groups (χ2=148.16, P<0.05). ConclusionQCC activity can not only reduce the adverse events incidence of needle indwelling, but also improve the nurses' working enthusiasm and responsibility, problem-solving skills and accomplishment, and promote team cohesion.
