Effect of Modified Radial Artery Cannulation Site on IABP Monitoring Stability

China486 participantsStarted 2025-09-15

Plain-language summary

Invasive arterial blood pressure (IABP) monitoring is critical for perioperative and critically ill patients, yet traditional radial artery cannulation near the wrist joint is prone to catheter dysfunction (e.g., kinking, occlusion) due to positional changes, compromising accuracy and patient safety. This trial hypothesizes that modifying the cannulation site to 1.5-2.5 cm proximal to the radial styloid process may enhance catheter stability.

Inclusion criteria

✓. Patients 18-75 years of age undergoing elective surgery who require radial artery cannulation;
✓. Patients positioned in supine, lithotomy, or other face-up surgical postures;
✓. American Society of Anesthesiologists (ASA) physical status classification: Grades I to III.

Exclusion criteria

✕. Abnormal results from the modified Allen test;
✕. Patients with a history of radial artery cannulation within the past 3 months, or with infection/trauma at or adjacent to the puncture site;
✕. Coagulopathy or hypercoagulable state;
✕. Patients undergoing anticoagulant therapy;
✕. Comorbid vascular diseases (e.g., vasculitis);
✕. Patients undergoing surgical procedures involving the same anatomic region;
✕. Preoperative hemodynamic instability (including patients already on vasoactive medications, or with atrial fibrillation, atrial flutter, atrioventricular block of grade II or higher, multifocal ventricular premature beats, or ventricular premature beats with R-on-T phenomenon);
✕. Patients lacking legal capacity to sign informed consent.
