早产儿应用经外周静脉置人中心静脉导管非正常拔管的原因

目的分析早产儿经外周静脉置入中心静脉导管（PICC）术后非正常拔管的原因。方法回顾性分析了104例应用PICC导管早产儿的临床资料，对其非正常拔管原因进行分析。结果104例早产儿中，93例（89．4％）为正常拔管，11例（10．6％）为非正常拔管。非正常拔管组患儿PICC管尖端位于锁骨下静脉比例明显高于正常拔管组患儿（x2=24．931，P=0．000）。非正常拔管组患儿的平均置管长度为（8．4±2．2）cm，明显低于正常拔管组的（10．2±1．6）em（t=3．391，P=0．001）。结论导管尖端未达到腔静脉可能是导致PICC非正常拔管的主要原因。

Causes of non-elective removal of percutaneously inserted central venous catheters in premature infants

Objective To analyze the causes of non-elective removal of pereutaneously inserted central venous catheters (PICC) in premature infants. Methods We retrospectively collected the clinical data of 104 premature infants and analyzed the causes of non-elective removal of PICC. Results PICC was removed when the treatment was finished (n = 93, elective removal group) or due to complications ( n = 7, non-elective removal group). In non-elective removal group, the percentage of catheter tip located in the subclavian jugular was signifi-cantly higher in non-elective removal group than in the elective removal group (X2 = 24.931, P = 0. 000 ). The length of inserted catheter was ( 8.4 + 2.2 ) cm in the non-elective removal group and ( ( 10.2:1:1.6) cm in the elective removal group ( t = 3. 391, P = 0. 001 ). Conclusion The main cause of non-elective removal of cathe-ters in premature infants may be that catheter tip fails to reach the vena cava.
