cannulation
Pronunciation: kan-yoo-LAY-shun
Surgical placement of tubes (cannulae) into blood vessels to establish cardiopulmonary bypass circuit.
Full Definition
Cannulation is the surgical procedure of inserting cannulae into major blood vessels to establish the cardiopulmonary bypass circuit. Arterial cannulation is typically performed in the ascending aorta or femoral artery for blood return, while venous cannulation involves the right atrium or vena cavae for blood drainage. Proper cannulation technique and positioning are critical for adequate bypass flow and prevention of complications such as air embolism or vessel injury.
Usage
Usage note: Specify arterial and venous cannulation sites in documentation for clarity.
