Validity of different formulas to predict lengths of the right internal jugular vein catheterization by anterior ap-proach / 局解手术学杂志

ABSTRACT

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 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.
