Surface Landmarks and C-length as Predictors of Depth of Right IJV Catheter Insertion: A TEE-Guided Study

No results posted yet for this study

Summary

The primary aim of this study is to derive a prediction rule to estimate the required length for placement of the CVC tip at the mid-point of the SVC from simple anatomical landmarks that are consistent with the known surface projections of the great veins. The accuracy of this rule will be examined using TEE and is intended for adult patients undergoing cannulation of the right IJV utilizing a middle approach. As a secondary aim, we will examine the performance of this suggested rule as contrasted with two other popular methods for estimation of the CVC length, the Peres formula and the C-length method.

Conditions

  • Catheterization, Central Venous
  • Echocardiography, Transesophageal
  • Anatomic Landmarks
  • Radiography

Interventions

PROCEDURE

Catheterization of internal jugular vein

The right internal jugular vein will be cannulated under transesophageal echocardiographic (TEE) guidance in order to place the catheter tip in the mid-SVC. The length of the catheter required to place the tip at the mid-SVC as guided by TEE will be regressed on the C-length or on the distance from the entry point to the surface point corresponding to the mid-SVC on the chest wall in order to obtain a predictive equation. The accuracy of either equation will be assessed by estimation of the standard error of the estimate (SEest).
