Accuracy of Classical Anatomical Landmark Technique ( Anterior, Central, and Posterior Approach) for Internal Jugular Vein by Ultra-sound Technique / 医学研究杂志

ABSTRACT

Objective To explore the accuracy rate of classical anatomical landmark technique ( anterior , central , and posterior ap-proach) for internal jugular vein (IJV) by ultrasound technique.Methods Sixty-four patients with selective operation were included in this study.The anesthetist marked the anterior approach , central approach, and posterior approach for internal jugular vein at 0°(neu-ral), 30°,and 80°of head rotation, respectively.The accuracy of each anatomical landmark were examined by other anesthetist with ul -trasound technique .Results The accuracy rate of anterior approach and central approach were significantly higher than posterior ap -proach at 0°of head rotation, respectively.The accuracy rate of anterior approach was higher than posterior approach at 30°of head rota-tion.The accuracy rate was similar among anterior , central, and posterior approach at 80°of head rotation.Conclusion The accuracy rate was different in different approach of anatomical landmark for internal jugular vein .
