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.
