规范导管维护措施预防早产儿PICC堵管的效果

Effect of standard catheter management for prevention of PICC occlusion in premature infants

目的探讨规范导管维护措施对早产儿经外周置人中心静脉导管（PICC）堵管的影响。方法2009年5月后对留置PICC的早产儿实施规范导管维护措施，比较干预前后PICC堵管发生率。结果干预后早产儿PICC堵管发生率从干预前的13．85％下降到2．94％，差异具有统计学意义（x2=5．209，P〈0．05）。结论规范导管维护措施对预防早产儿PICC堵管有明显的成效。

Objective To explore the effect of standard catheter management to prevent the PICC occlusion in premature infants. Methods After May 2009, PICC nursing teams were organized and trained on improving the methods of flushing and sealing the catheter and the occlusion rates before and after intervention was analyzed. Results The study outcome showed a significant reduction in the catheter occlusion rate, from 13.85% to 2.94%, and the difference was statistically sighificant （ X2 = 5. 209, P 〈 0.05 ）. Conclusions Standard catheter management has remarkable effect in preventing PICC occlusion in premature infants.
