Comparative efficacy evaluation of an original ultrasound-guided technique for peripheral venous catheterization in the prevention of surgical complications

In patients with difficult venous access, the chance of peripheral catheterization failure and local complications significantly increases. Ultrasound guidance reduces the risks, but optimal probe orientation remains a matter of debate. Objective. The aim of the study is to compare traditional short-axis and long-axis probe placement methods with the author’s novel oblique placement technique. Materials and Methods. This open-label, randomized study included 300 patients (426 catheterizations) from various departments of a multi-speciality hospital. Participants were divided into 3 groups (100 in each): short-axis, long-axis, and oblique placement. The authors evaluated the number of attempts until successful catheterization, procedure time, and complications. Results. The oblique placement technique provided a higher first-pass success rate and shorter catheterization time compared to both the short-axis and long-axis probe placement methods. The complication rates did not differ significantly. Conclusion. The oblique ultrasound transducer placement technique for peripheral vein catheterization in patients with difficult venous access increases the first-pass success rate and shortens the procedure time not increasing complication rates. The data obtained support the wider implementation of the approach into clinical practice.
