术前留置套管针患者发生静脉炎的原因分析和护理干预

The risk factors and preventive measures of phlebitis in patients with preoperative indwelling needles

目的探讨术前留置套管针患者发生静脉炎的原因和预防对策。方法分析2013年1-6月57例留置套管针的患者术后发生静脉炎的原因,在选择穿刺部位、选择套管针型号、套管针及附件固定、留置套管针穿刺技术等方面进行改进。结果 2013年7-12月术前留置套管针患者发生静脉炎5例（0.2%）,低于干预前的静脉炎发生率（χ2=50.28,P〈0.01）。结论根据患者具体情况、手术类型选择合适的套管针,选择合适的穿刺部位,规范套管针及附件的固定,对护士进行留置套管针穿刺培训,可有效减少患者静脉炎发生率。

Objective To investigate the risk factors and preventive measures of phlebitis in patients with preoperative indwelling needles. Methods The risk factors of phlebitis were retrospectively analyzed based on the data of 57 cases with preoperative indwelling needles from January to June in 2013. Aimed at the risk factors,some preventive measures were carried out in aspects of selection of proper puncture site,the type of indwelling needles,fixation method and puncture techniques. Results The incidence of phlebitis in patients with indwelling needles decreased from 2.8% to 0.2%（P〈 0.01）. Conclusion Selection of proper type of indwelling needles,punc ture site and standardized fixation method can effectively decrease the incidence of phlebitis in patients with preopera-tive indwelling needles.
