Objective Exploring the role of arterial puncture and catheterization in the monitoring of invasive blood pressure in critically ill patients. Methods Collect data from 100 critically ill patients who underwent IBPM from July 2024 to July 2025. Divided into control group and observation group according to different puncture methods. The control group used conventional radial artery puncture catheterization (n=50 cases). The observation group used radial artery puncture and catheterization through the snuff bottle area (n=50 cases). Compare the arterial puncture related indicators, wrist joint function, retention and compression time, and pain level between the two groups. Results The arterial puncture related indicators, wrist joint function, retention and compression time of the observation group were significantly better than those of the control group patients, and the pain level was significantly lower, with statistical significance (P<0.05). Conclusion The use of arterial puncture and catheterization through the snuff bottle area for invasive blood pressure monitoring can improve the success rate of puncture, reduce the number, duration, and compression hemostasis time of puncture, prolong the retention time, reduce patient pain, and have minimal impact on wrist joint function.
