• The radial artery is commonly selected because it is superficial, relatively fixed, and has lower distal ischaemia risk than several alternative approaches. — Effects of modified site for radial artery cannulation on the stability of arterial blood pressure monitoring in patients undergoing elective surgery (MoSRAC): protocol for a randomised controlled trial
• Conventional radial artery cannulation is performed near the wrist joint at maximal pulsation adjacent to the radial styloid process. — Effects of modified site for radial artery cannulation on the stability of arterial blood pressure monitoring in patients undergoing elective surgery (MoSRAC): protocol for a randomised controlled trial
• Wrist movement near the conventional site can mechanically disturb the catheter and cause catheter or vessel problems. — Effects of modified site for radial artery cannulation on the stability of arterial blood pressure monitoring in patients undergoing elective surgery (MoSRAC): protocol for a randomised controlled trial
• The modified site is intended to avoid the wrist joint's mechanical stress centre while preserving practical access near the distal radial artery. — Effects of modified site for radial artery cannulation on the stability of arterial blood pressure monitoring in patients undergoing elective surgery (MoSRAC): protocol for a randomised controlled trial
• Prior studies suggest that more proximal radial artery sites may improve some catheter performance or insertion outcomes, but they did not focus on intraoperative catheter function. — Effects of modified site for radial artery cannulation on the stability of arterial blood pressure monitoring in patients undergoing elective surgery (MoSRAC): protocol for a randomised controlled trial
