摘　　要：目的探讨估测右颈内静脉前路法置管长度最适宜的公式。方法选取2013年1月至2013年6月我科经右颈内静脉留置深静脉导管患者67例,分别用4种公式对置入导管长度进行估测,并与实际置入至正确位置的长度进行比较,分析4种公式的准确性。结果 4种公式估测置入长度的误差百分比均在15%以内。公式1估测长度与实际长度无明显差异(P>0.05);其余3种公式的估测长度均明显小于实际长度,有明显差异性(P<0.05)。在对不同身高患者置管长度的预测中,公式4的平均绝对误差明显高于公式1,有明显差异性(P<0.05);公式2、公式3与公式1的绝对误差平均值比较均无显著性差异(P>0.05)。结论4种公式预测长度误差均在15%以内,其中公式1简单、准确、实用、误差小,更适用于右颈内静脉置管前路法长度的估计。Objective To explore the most effective formula to predict the catheterization length of the right internal jugular vein by an-terior approach. Methods Sixty-seven cases performed with right internal jugular vein catheterization from January 2013 to June 2013 were enrolled in this study and 4 formulas were selected to predict the catheterization lengths. Comparing their predicted lengths with the actual lengths defined as the lengths of the internal catheters which terminals were inserted to a accurate position,and analyse their predictive validi-ty. Results The predictive error percentages of the 4 formulas were all less than 15%. Comparing the predicted lengths and the actual lengths, there was no difference between the predicted length of the 1st formula and the actual one（P〉0. 05）,and the predicted lengths of the other three formulas were significantly less than the actual ones（P0. 05）. Conclusion The predictive error of all the 4 formulas is less than 15%, and the 1st formula is＆nbsp;simple,practical and associated with a much smaller error,more suitable to estimate the length of the right internal jugular vein catheterization by anterior approach.
