Clinical evaluation of the right internal jugular vein puncture and catherization guided by ultrasound diagnostic location

Objective:To evaluate the clinical value and safety of the right internal jugular vein puncture and catherization guided by ultrasound diagnostic location.Methods:Two hundred and four patients scheduled by operation with the right internal jugular vein puncture and catherization guided by ultrasound diagnostic location were divided into the conventional surface mark positioning(group A),long axial group(group B),long-short axial group(group C) and short axial group(group D) according to the random number table(51 cases each group).Puncture conditions in four groups were recorded.Results:The differences of the puncture success rates between four groups were statistically significant(P<0.01),the differences of the puncture success rates between A,B and C groups were not statistical significance(P>0.05).The puncture condition in A group was worse than that in B,C and D group,the differences of which were statistically significant(P<0.05 to P<0.01).The differences of test times and number of puncture site between B,C and D group were not statistically significant(P>0.05).The differences of adjusting direction times,puncture time and technical difficulty score between B,C and D group were statistical significance(P<0.05 to P<0.01),but in B and C groups,the difference of which was not statistically significant(P>0.05).The incidences of complications in group B and C were lower than that in group A(P<0.05),while the difference of which between A and D group was not statistically significant(P>0.05).Conclusions:The right internal jugular vein puncture and catherization guided by ultrasound diagnostic location is safe,high successful rate.The long-short axial puncture method has the advantages of both long and short axis,which can improve the successful rate,efficacy and safety,and is worthy of clinical promotion.
