改进无菌透明敷贴对留置针留置状况的效果评价

Evaluation on effect of improved sterilized transparent dressing on indwelling status of indwelling needle

目的探讨裁剪无菌透明敷贴与未裁剪无菌透明敷贴固定留置针之留置时间的对比分析。方法选择2016年8-12月住院患者236例,住院号尾数是奇数的设为试验组(119例);住院号尾数是偶数的设为对照组(117例)。留置针型号为18GA,穿刺1次成功,输液疗程大于5d,试验组用裁剪无菌透明敷贴固定留置针,将延长管完全暴露于敷贴外,对照组则采用传统的留置针敷贴固定方式。记录两组留置针留置24、48、72、96、>96h因回血堵管率、平均留置时间及静脉炎的发生情况。结果试验组留置48、72、96、>96h回血堵管情况均优于对照组,差异有统计学意义(P<0.05);试验组平均留置时间(72.12±3.25)h,对照组(59.34±3.78)h,差异有统计学意义(P<0.05);试验组发生7例静脉炎,对照组9例,差异无统计学意义(P>0.05)。结论应用裁剪的无菌透明敷贴固定留置针减少了回血,降低了留置针因回血凝固的堵管率,延长了留置针使用时间,提高了患者满意度且不增加静脉炎发生的风险。

Objective To conduct the contrastive analysis on the indwelling time of fixing indwelling needle by cutting sterile transparent dressing and non-cutting sterile transparent dressing. Methods A total of 236 inpatients in this hospital from August tO December 2016 were selected. The patients with odd at last number of admission number served as the experimental group （119 cases）,while the patients with even at the last number of admission number served as the control group（117 cases）. The indwelling needle type was 18GA, the puncture was once success and the fluid infusion course was more than 5 d. The experimental group used the cutting sterile transparent dressing for fixing the indwelling needle and the extension tube was completely exposed to the outside of dressing, while the control group adopted the conventional indwelling needle application fixation mode. The blood returning plug-ging pipe rate,average indwelling time and phlebitis occurrence at 24,48,72,96, 〉96 h after indwelling needle were recorded. Results The blood returning plugging tube situation at 48,72,96,〉96 h after indwelling needle in the experimental group was supe- rior to that in the control group, the difference was statistically significant（P〈0.05）;the average indwelling time in the experimen- tal group was （72.12±3.25）h, while which in the control group was （59.34±3.78）h, and the difference was statistically significant （P〈0.05）. Seven cases of phlebitis occurred in the experimental group and 9 cases in the control group, the difference was not statistically significant（P〉0.05）. Conclusion Applying cutting sterile transparent dressing for fixing the indwelling needle reduces the plugging pipe rate due to returning blood coagulation, extends the indwelling needle use time,increase the patient＇s satisfaction, moreover does not increase the phlebitis occurrence risk.
