Effect of Improved Subclavian Vein Puncture on Success Rate

Objective To probe into the method of subclavian vein puncture and intubation,seek optimal site of puncture to improve the success rate of one-time puncture.Method Applying new site of puncture in the Improvement Group-Puncture at the cross area between the lower edge of the middle of clavicle and 0.5～1 cm away from 1cm above the second rib edge,the needle aimed to the upper notch of the sternoclavicular joint bone,slowly and steadily advance the needleunderneath the clavicle into the depth of 3～4 cm,intubation depth:12 ～15 cm;While applying traditional puncture site-Subclavian vein puncture in the Traditional Group:Puncture at a distance of 0.5～1 cm from the lower edge of the middle of clavicle,needle aimed to the sternoclavicular joint,intubation depth:12～15 cm.Follow-up assessment was conducted on the success rate and complications.Result Among 45 cases in the Improvement Group,44 cases were successful with one-time puncture,1 case was successful with a second time puncture,puncture success rate was 100%;while among 45 cases in the Traditional Group,29 cases were successful with one-time puncture,10 cases were successful with a second time puncture,6 cases failed,puncture success rate was 86.67%.There's an obvious difference between the groups on puncture success rate(χ2=4.4643,P0.05). Conclusion Improved subclavian vein puncture is simple to locate,lock in place,nurse and operate with high success rate of one-time puncture,which will not affect the movement of the patients'neck,upper and lower limbs and deserves clinical application.
