早产儿PICC送管体位与导管异位关系研究

The Study of Relation Between Position of Delivery PICC and Catheter Displacement in Premature

目的探讨早产儿PICC(Peripherally Inserted Center Catheter,PICC)穿刺时送管体位与导管异位关系。方法将实施PICC置管的早产儿随机分为平卧位组和坐位组。平卧位组送管时患儿平卧,穿刺侧手臂外展大于90°,当导管位置到达肩部时助手将患儿头偏向穿刺侧,下颌贴近锁骨;坐位组在导管送入肩部时助手托起患儿,头偏向穿刺侧,下颌贴近锁骨,躯干与操作台面垂直。结果平卧位组48例患儿中导管末端位于上腔静脉37例,导管异位率22.92%;坐位组47例患儿中导管末端位于上腔静脉30例,导管异位率36.17%;两组资料比较差异无统计学意义,P>0.05。结论早产儿PICC导管细、软、轻,重力作用小,平卧位送管操作简单、方便。

Objective To explore the relation between position of delivery catheter and catheter displacement during PICC for premature infants. Methods 95 cases who received peripherally inserted center catheter were divided into supine group and sitting group randomly. The infants were put in supine when delivery the catheter of PICC, the arm of puncture side was outreach greater than 90° ,the head shift to puncture side and the jaw was close to clavicle when the catheter were pass shoulder in supine group. The assistant hold up the premature make his trunk vertical to the console, the head shift to puncture side and the jaw was close to clavicle when the catheter was pass shoulder in sitting group. Results The rate of catheter displacement was 22.92% （37/48） in supine group and 36.17% （30/47） in sitting group, the different between was not significant（ P 〉 0.05 ）. Conclusion The catheter of PICC which applied in premature was fine, soft, and light, with small gravity. It＇ s simple and convenient that make the premature in supine position when delivery the catheter of PICC.
