• The primary outcome defines arterial catheter dysfunction as the proportion of enrolled participants with abnormal catheter function in each group. — 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
• Catheter dysfunction includes kinking, dislodgment, lumen occlusion, waveform damping, and loss of blood withdrawal. — 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
• Catheter dysfunction can distort blood pressure readings, require catheter replacement, and create patient-safety risks. — 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
• Movement can produce position-dependent waveform abnormalities, abnormal damping, or signal loss through mechanisms such as spasm, kinking, or tip apposition. — 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
• A prior survey reported that most anaesthesiologists had encountered partial arterial catheter occlusion and many had encountered complete occlusion. — 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
