Ultrasound-guided radial vein cannulation for general anesthesia in cases with difficult peripheral venous access: a report of two cases.

BACKGROUND

Despite advancements in ultrasonography, locating peripheral veins for catheter placement remains a challenge in patients with altered anatomy owing to multiple surgeries. Herein, we highlight the potential of using the radial vein as an alternative site for ultrasound-guided peripheral venous catheterization.

CASE PRESENTATION

We present two cases of patients with extensive surgical histories, including multiple abdominal surgeries, leading to difficult peripheral venous access. Traditional sites for peripheral venous catheterization were unsuitable due to vein narrowing or lack of visibility. In both cases, ultrasonography helped identify the radial vein as the only viable site for catheter placement. The patients underwent successful ultrasonography-guided catheterization of the radial vein without complications, facilitating medical management, including anesthesia induction and intraoperative monitoring.

CONCLUSIONS

The radial vein is a feasible and safe alternative for ultrasound-guided peripheral venous access in patients where traditional venous access sites are compromised.
