Outline of Final Research Achievements |
To eliminate puncture-related complications, it is important to select a safe puncture line that allows the needle tip to remain in the vessel even during deep puncture and to avoid losing the needle tip. In this study, the puncture of the confluence of the internal jugular and subclavian veins from the supraclavicular fossa was shown to have the longest overall puncture safety margin and the least contact with the posterior vessel wall compared to other sites because the needle tip was directed toward the brachiocephalic vein. The use of the needle-guide attachment enables simple and safe puncture with less chance of the needle tip coming off the echo section. The appropriate needle length was 70 mm. US with CT data is expected to be an educational and training tool for residents because it can provide information on regions and deep structures that are blinded by US.

Academic Significance and Societal Importance of the Research Achievements |
中心静脈穿刺における、鎖骨上からのアプローチで、内頚・鎖骨下合流部穿刺による穿刺方法の報告はこれまでにみられないもので広く知られていない。この穿刺方法における安全性や有用性の周知は、穿刺合併症低減に大きく寄与できる可能性がある。 また、ニードルガイドアタッチメント併用時の適正な針の長さに関する報告も知る限りみられない。本研究データでの適正な有効長設定は、安全な穿刺付属キットの再考の一助となると思われる。
