Localización de la punta del cateter venenoso central mediante control electrocardiográfico, Hospital Vicente Corral Moscoso, Cuenca 2010

Abstract

Use of central venous catheter (CVC) has become general, there are several techniques applied for its positioning and depends, to a great extent, of the preference and experience of places who it. Once installed a central line, correct location of the tip of catheter is importance very much. In this point the guide with electrocardiographic control assures a suitable location and greater effectiveness in relation to the methods classically used.

Objective: To validate cardioscopía as method for the suitable location of the tip of CVC in the of subclavian vein catheterization in front of the chest radiograph control applied in patients of the Hospital Vicente Corral Moscoso. Methods: A study of validation of diagnostic test for the location of the tip of CVC by subclavian via was realized, 142 were included patients.

Results: Central venous catheterization by subclavian vein via was realized to the study population, of them was reached a positive result in the electrocardiographic guide in 90 patients (63.4%). The location of the tip of CVC was verified according to the standard method used in our means, the thorax x-ray and it was observed that the 77.78% of the electrocardiogram-guided central venous catheterization were correctly placed, whit a RP of 3.67 (IC 95% = 2.15 -6.28 p = 0.000), demonstrating the validity of the method in study. Also one determined that the distance skin/tip of the catheter average for the population in study is of 11.5 ±1.27cm

Conclusions: Use of Electrocardiogram-guided central venous catheterization technique is most reliable that method done blindly, to ensure an adequate placement of tip of CVC.

Key Words: Venous central catheterization, electrocardiographic monitoring.
