极低出生体重儿行PICC置管时患儿体表测量长度和理想置管深度的关系

Relationship analysis of length of body surface measurement and ideal depth of tube detaining in very low birth weight infant with PICC

目的：分析极低出生体重儿（VLBWI）行PICC置管时患儿体表测量长度（LBSM）和理想置管深度（IDTD）的关系。方法选择2012年5月-2014年1月于徐州市儿童医院新生儿重症监护室上肢植入PICC的40例贵要静脉置管及24例头静脉和肘正中静脉PICC置管的VLBWI患儿。分析对行PICC置管时LBSM和IDTD的关系。结果40例贵要静脉置管结果表明，获得理想深度的比例最高，为67.50豫；置入过深次之，置入过浅的比例最低，仅为12.50豫。 Pearson相关性分析显示，除左侧头静脉的LBSM与IDTD无相关性之外（r =0.397，P=0.512），其余各处静脉均有相关性。经回归分析，LBSM与IDTD的回归方程如下：右侧的贵要静脉：Y =-6.23±1.01X；右侧的头静脉：Y =-14.36±1.15X；右侧的肘正中静脉：Y =4.12±0.82X；左侧的贵要静脉：Y =2.86±0.84X；左侧的肘正中静脉：Y =-19.52±1.23X。结论在VLBWI右侧的贵要静脉进行置管时LBSM与IDTD的具有较好的相关性，临床治疗时应予以重视。

Objective To study the relationship of length of body surface （LBSM ） measurement and ideal depth of tube detaining （IDTD） in very low birth weight infant （VLBWI） with PICC. Methods From May 2012 to January 2014, in NICU of the Children＆#39;s Hospital of Xuzhou City, 40 VLBWI with upper PICC and 24 VLBWI with cephalic vein and cubital vein PICC were selected. The relationship of LBSM and IDTD at PICC was analyzed. Results The results of 40 VLBWI with upper PICC showed that the highest was IDTD acquired, for 67.50%, the next was followed placed too deep, the lowest was too shallow into the lowest percentage, only 12.50%. The result of Pearson correlation analysis showed except the left cephalic vein of LBSM had no correlation with IDTD （r=0.397, P=0.512）, the rest were corre-lated throughout the vein. By regression analysis, LBSM and IDTD regression equation was as follows, the right side of the vein：Y =-6.23±1.01X;the right of the cephalic vein：Y =-14.36±1.15X;the right of the median cubital vein;Y =4.12±0.82X; the left side of your vein; Y = 2.86±0.84X; the left of the cubital vein： Y = -19.52±1.23X. Conclusion When the right side of VLBWI vein catheterization to have a good correlation with IDTD LBSM, the clinical treatment should be valued.
