Comparison of the effects of modified puncture and traditional puncture on subclavian vein puncture

Abstract

Objective To compare the success rate of puncture and complications in subclavian vein puncture between modified puncture and traditional puncture, and explore a safer and more effective subclavian puncture method. Methods From June 2016 to June 2017, 200 patients (100 males and 100 females) who underwent subclavian vein catheterization were randomly divided into traditional group, modified group, traditional ultrasound group and modified ultrasound group 50 patients in each group. The traditional puncture method and modified puncture method, ultrasound-guided traditional puncture and ultrasound-guided were used to improve puncture line subclavian vein catheterization. The puncture success rate, puncture time, punctures frequency and related complications were compared between the 4 groups. Results (1) The successful rate of puncture assembly in the modified group was 98.0%(49/50) and the success rate of primary puncture was 90.0%(45/50), which were significantly higher than those in the traditional group [94.0%(47/50) and 64.0%(32/50), all P values 0.05). Conclusions Ultrasound guided descending subclavian vein catheterization is safer, with high success rate and fewer complications, especially for patients with difficult puncture. The improved puncture method has obvious advantages over the traditional puncture in the clinical application of subclavian vein puncture, the puncture success rate is higher, less complications, it is worth promoting. Ultrasound guided descending subclavian vein catheterization success rate, less complications, more safe and efficient, especially for patients with puncture difficulties, there is an important clinical value.
