Compensatory response of the radial and ulnar arteries after radial artery cannulation in hypertensive patients

Limited literature exists on the vascular reactivity of the radial and ulnar arteries in hypertensive patients following radial artery cannulation. This study assessed the vascular reactivity of the radial and ulnar arteries by comparing Doppler images and laser speckle contrast imaging (LSCI) obtained from both normotensive and hypertensive patients after radial artery cannulation under general anesthesia.
