Application of Ultrasound-Guided Internal Jugular Vein Catheterization in a Non-Classical Position

Objective:To explore the clinical application value of ultrasound-guided internal jugular vein catheterization in a non-classical position.Methods:We retrospectively reviewed the clinical data of 40 cases in our institution from 2010 to 2012.All patients underwent internal jugular vein catheterization in a non-classical position.35 cases were cannulated using the traditional method of anatomic landmarks(Group A),and 33cases' cannulation was guided using an ultrasound imaging(Group B).The success rate,numbers of cannulation attempts,puncture time,and complication were recorded.The relationship of the internal jugular vein to the common carotid artery was compared between the two kinds of position.Results:The cannulation success rate at first attempt in group A and group B was 5.7% and 63.6%,respectively(P0.01),and the total success rate was 20.0% and 90.9%,respectively(P0.01).The number of attempts were less in group B than that in group A(P0.05).And the incidence of complication was 37.1% ingroup A and 3.0%in group B(P0.01).45.7% patients in group A showed internal jugular vein located in anterolateral common carotid artery,which is more than that in group B(15.2%,P0.05).25.7% patients in group A showed internal jugular vein located in anterior of common carotid artery,which is more than that in group B(42.4%,P0.05).Conclusion:Ultrasoundguided internal jugular vein catheterization in non-classical position is superior to the landmarks technique in terms of success rate,and could decrease incidence of complication.
