Intravenous Access Using Infrared Laser

Peripheral Intravenous Cannulation With Support of Infrared Laser Vein Viewing System in Obese Patients

Peripheral venous access is a prerequisite for anesthesiological for surgical patients.It is often difficult to establish and potentially painful in obese patients (Body mass Index > 35). AV300 uses near infrared laser light to improve visibility of peripheral veins and could help cannulating them. The aim of this study was to examine if use of Accuvein(®) AV300 vein viewer could facilitate venous cannulation in obese patients (surgical and obstetric).
