PICC在低出生体重儿不同血管穿刺置管效果的研究

The effect of different blood vessel puncture and canula of PICC on the low weight infants

目的研究经外周静脉置人中心静脉导管（Peripherally Inserted Central Catheter，vice）应用于低出生体重儿作为中长期静脉通道不同部位穿刺时问、留置时间、完成治疗情况、护理以及并发症的发生率及处理。方法对2007年1月至2008年10月在NICU中所有置人PICC的低出生体重儿进行前瞻性研究，详细记录研究期间NICU应用PICC导管的低出生体重儿临床资料，并对资料进行统计学分析。结果研究期间有20例低出生体重儿置入PICC导管20根，以提供静脉营养、抗感染治疗、血管活性药物。急救是放置PICC导管的常见原因，经腋静脉置管导管平均放置（14．00±1．50）d，经肘部静脉（肘正中静脉或贵要静脉）置管导管平均放置（24．00±8．19）d，不同静脉置管并发症的发生率有显著差异。结论PICC导管为低出生体重儿提供了可靠安全的中长期静脉通道，降低了护理人员的工作量，避免了反复外周静脉穿刺给患儿造成的不良刺激，贵要静脉置管系首选静脉。

Objective To research about puncture time, indwelling time, cure situation, nursing, frequency and disposal of syndrome when PICC applied on different position puncture in long ＆ medium vein channels for low weight infants. Methods Foreground research and detail record on the clinic materials on low infants with PICC in NICU form January 2007 to October 2008 were statistical analyzed. Results 20 canulas of PICC were placed in 20 low weight infants respectively to provide vein nutrition, anti - infectious cure and active medicines for blood vessel. The reason of placing PICC canulas was the need for first aid, the average time of containing PICC through axillary vein was 14. 00 d, and 24. 00 d through basilica vein. The frequency of syndrome for different veins had different. Conclusions PICC provides reliable and safe long ＆ medium time vein channels for low weight infants, and decreases the burdens of nursing staff and avoids the ill stimulation of repetitive around vein puncture for infants. The vein lays first choice among vein canulas system.
