Application of multifunctional pulse wave sphygmomanometer combined with constant temperature ice in patients with forearm hematoma after coronary intervention.

AIM: This study aims to investigate the effects of combining a multifunctional pulse wave sphygmomanometer with constant temperature ice on patients with forearm hematoma following coronary intervention.

METHODS

Patients who developed forearm hematoma after undergoing coronary intervention from March 2021 to March 2023 at our hospital were selected as the study cohort. Using a random number table, they were divided into two groups the control group and the research group. The control group received cuff compression treatment using a multifunctional pulse wave sphygmomanometer. The primary endpoint was the effective rate of one compression. Secondary endpoints included body surface temperature, pain, comfort, arm measurements, and swelling value.

RESULTS

A total of 190 patients were included, with 95 in the control group and 95 in the research group. The research group showed a significantly higher effective rate of one compression compared to the control group (87.2% vs. 95.8%, p = 0.035). Additionally, the research group experienced significantly reduced pain (2.0 [2.0,3.0] vs. 1.0 [1.0,2.0], p < 0.001) and improved comfort levels. This approach also effectively reduced body surface temperature (32.91 ± 0.83℃ vs. 12.09 ± 1.09℃, p < 0.001), arm measurements (274.32 ± 9.56 mm vs. 271.15 ± 8.82 mm, p = 0.019), and swelling value (12.40 ± 1.95 vs. 11.07 ± 2.13, p < 0.001) after compression.

CONCLUSIONS

The combined use of a multifunctional pulse wave sphygmomanometer for cuff compression on forearm hematoma with simultaneous constant temperature ice application demonstrated more benefits. This approach effectively reduced pain, improved comfort levels, and enhanced compression-based hemostasis and reduction of swelling.
