Successful Distal Radial Artery Puncture for Invasive Arterial Blood Pressure Monitoring in Hemodynamically Unstable Patients.

Invasive arterial blood pressure (ABP) monitoring is essential for critically ill patients. This case series evaluates the efficacy of distal radial artery (dRA) puncture for invasive ABP monitoring, focusing on procedural success, patient outcomes, and procedural limitations. Three patients with acute coronary syndromes underwent dRA puncture for invasive ABP monitoring after percutaneous coronary intervention. The procedures were successful, with no significant complications. The use of dRA preserved proximal radial artery function and improved patient comfort. dRA is a viable alternative to conventional radial artery access for ABP monitoring; the potential benefits include reduced complications and preserved arterial function. The key points to avoid puncture complications include accurately assessing the location of the arterial pulse, using a modified Seldinger technique, avoiding forceful maneuvers, and applying adequate pressure after catheter removal.
