title: The technique of radial artery cannulation. Tips for maximizing results while minimizing the risk of complications.
abstract: Arterial cannulation is usually performed to allow continuous blood pressure monitoring or frequent arterial blood sampling. Relative contraindications to the procedure include bleeding abnormalities and peripheral vascular disease. The radial artery is the site most frequently used because the hand generally has good collateral circulation. Percutaneous cannulation is the preferred method of insertion. To avoid transecting the artery, advance the needle-catheter assembly slowly; blood return confirms arterial placement. there should be no resistance to needle advancement. Bleeding is the most common complication of arterial cannulation, but ischemia and infection have greater clinical significance.
