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(P<0. 05). Comparing the mean absolute predictive errors of the 4 formu-las in the 3 height groups of 150~159 cm,160~169 cm and 170~179 cm,respectively,those of the 4th formula were all significantly higher than those of the 1st formula in all the 3 groups(P<0. 05);and no differences between those of the 2nd or the 3rd formula and those of the 1st formula were observed(P>0. 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.
