Effect of hyperperfusion on successful collection of arterial blood gas specimens in patients with acute heart failure

Abstract

Aim: This study aimed to explore the effect of radial artery flow hyperperfusion on the successful collection of radial artery blood gas specimens in patients with acute heart failure.

Methods: From February 2023 to December 2024, 548 patients with acute heart failure in the database of the emergency rescue room of our hospital were divided into two groups: non-hyperperfusion group and hyperperfusion group. In the hyperperfusion group, arterial blood gas was collected using the radial artery hyperinfusion method. The primary endpoint was the success rate of one-time puncture and the success rate of total puncture. Secondary endpoints included puncture frequency of >3 times, puncture time, pain, puncture site hematoma, puncture site bruise, and patients’ satisfaction.

Results: In total, 548 patients were included, including 223 in the non-hyperperfusion group and 325 in the hyperperfusion group. The hyperperfusion group exhibited a significantly higher success rate of one-time puncture (63.4% vs. 83.4%, p< 0.001) and success rate of total puncture (82.5% vs. 94.6%, p < 0.001) compared to the non-hyperperfusion group. Additionally, the hyperperfusion group experienced a significantly reduced number of patients with puncture frequency >3 times (26.2% vs. 9.9%, p < 0.001) and puncture time (48.59 ± 7.83s vs. 26.43 ± 6.44s, p < 0.001). This approach also effectively decreased the risk of puncture site hematoma (2.2% vs. 0.0%, p = 0.045), arm puncture place bruise (5.5% vs. 0.4%, p<0.001), and pain (3.0 [3.0,4.0] vs. 2.0 [1.0,2.0], p <0.001) and improved patients’ satisfaction after adopting the radial artery hyperinfusion method.

Conclusions: Radial artery hyperperfusion improved the success rate of puncture for radial artery blood specimen collection in patients with acute heart failure, reduced puncture complications, and improved patients’ satisfaction.
