title: [Accurate placement of central venous catheter--ECG-guided method vs patient height method].
abstract: Correct positioning of central venous catheters (CVC) is important. We compared the positioning of CVCs by ECG-monitoring via the guidewire and that by method using patient height. "Certofix" triple-lumen CVCs were inserted in 60 cardiac surgical patients via right internal jugular puncture. Of these, 30 were placed with ECG guidance via the guidewire (Group ECG), and 30 with reference to patient height (modified Pere's method) (Group H). The distance from CVC tip to the superior vena cava/right atrial junction (C-J distance) was measured by postoperative chest X-ray. There was no difference in height between the two groups. The depth of insertion of CVC and C-J distance (cm) were 15.1 +/- 0.3 and 3.6 +/- 2.0 in group H and 14.3 +/- 1.5 and 4.9 +/- 1.2 in group ECG, respectively, with no statistically significant differences between the two groups. In one case of group H, the catheter tip was placed in the right atrium. In group ECG, there was a significant correlation between height and the depth of insertion of CVC. In conclusion, ECG guidance via the guidewire is useful for avoiding CVC displacement.
