乙醇脱碘在 PICC 导管维护中的应用效果

目的：观察乙醇脱碘在PICC维护中的效果，探讨PICC维护中乙醇脱碘的必要性。方法将60例PICC置管患者采用抽签法随机分成两组，每组30例。对照组采用常规消毒换药护理，观察组采取常规消毒后，再用乙醇脱碘，待干，最后粘贴透明敷料。比较两组患者穿刺点皮肤表面菌落数、待干时间及换药总时间观察两组维护7d后贴膜卷边情况。结果两组患者穿刺点周围皮肤菌落数比较差异无统计学意义（t＝6．38，P＞0．05）；观察组消毒后自然待干时间（6．41±4．80）min、换药总时间（16．60±2.71）min，均低于对照组，差异有统计学意义（t值分别为6．38，2．89；P＜0．05）；对照组敷贴卷边＞2 cm患者占93．3％，观察组占10．0％，差异有统计学意义（χ2＝41．72，P＜0．05）。结论采用乙醇脱碘的维护方法能有效地缩短消毒液待干时间及换药总时间，提高工作效率，减少透明敷贴的卷边松动情况，减少穿刺点感染的几率，提高PICC置管的安全性。

Comparative research of removal alcohol with iodine or not in PICC maintenance

Objective To observe the effect of removal alcohol with iodine or not in PICC maintenance . Methods Sixty patients who had PICC were randomized into observation group （ n =30 ） and control group （ n=30 ） .Besides routine disinfection method and operation , the observation group used alcohol to remove the iodine.While the control group only received the routine disinfection method and operation .The bacterial cultivation of the skin surface around the PICC insertion site , drying time and time to change the dressing were compared between groups , and observed rolled-up dressing after 7 days of change the dressing .Results The bacterial cultivation of the skin surface around the PICC insertion site were not significantly different between groups （t=6.38,P〉0.05）.The natural air drying time and the total time of change the dressing of the observation group were （6.41 ±4.80） minutes and （16.60 ±2.71） minutes, which were significantly shorter than those of the control group （t =6.38,2.89, respectively;P ＆lt;0.05）.And the rolled-up dressing was 93.3%in the control group and 10.0%in the observation group .The difference was significant （χ2 =41.72, P〈0.05）.Conclusions Using alcohol to remove the iodine in PICC maintenance can shorten the nursing time and improve the work efficiency .It can also decrease the rolled-up dressing, reduce the rate of infection of the insertion site and increase the safety of PICC indwelling .What＆#39;s more, iodine on the skin removed with alcohol makes the patient feel much more comfortable .
