Optimal head rotation and puncture site for internal jugular vein cannulation after laryngeal mask airway insertion.

ABSTRACT:

Introduction

We studied the effect of head rotation on the relative position of the right common carotid artery (CCA) and the right internal jugular vein (IJV) in patients with laryngeal mask airway (LMA) insertion to evaluate the accuracy of anatomical landmarks for right IJV cannulation.

Methods

We simulated needle insertion to the right IJV on sonograms via the central landmark approach and an approach using the external jugular vein, in patients with LMA insertion (n = 50) or endotracheal intubation (E-tube, n = 50). Overlap index and successful simulation rates were measured according to the different degrees of head rotation.

Results

The overlap index between the right CCA and the right IJV increased with greater degrees of head rotation. It was significantly gr
