ABSTRACT |
BACKGROUND: Catheterization of central vein may cause fetal complications such as cardiac arrhythmia, cardiac temponade, atrial perforation etc. For prevention of these complications, tip of central venous catheter should located in superior vena cava. The purpose of this study was to investigate the optimal positioning of central venous catheters.
METHOD: From March 1996 to Jun 1996, a total of 50 patients who requiring central venous catheters were involved. First, we evaluate the accuracy of predetermined formula of 'Peres'. Second, we hypothesized that height of patients was correlated with optimal length of central venous catheters and we analysed relationship between height and optimal length of central venous catheters using simple regression analysis by SAS.
RESULTS: 1) Predetermined formula of 'Peres' inaccurately predicted required length of central venous catheter. The accuracy was 78%.
2) There were a linear relationships between height and optimal length of central venous catheter. Their relationships was followed, Y=0.09X(Y: optimal length of central venous catheters, X: height, p=0.0001, R2=0.39).
CONCLUSION: Using height of patients, we can accurately predict the optimal length of central venous catheters. |
