Objective To explore the effect of continuous cuff compression in improvement of forearm hematoma in patients with percutaneous coronary intervention.

Methods A total of 94 patients with coronary intervention for acute myocardial infarction in the hospital from September 2021 to September 2024 were selected as research objects, and they were divided into control group and observation group according to the random number table method, with 47 cases in each group. The control group adopted a customized sphygmomanometer combined with a conventional cuff for intermittent compression of the forearm hematoma, and the observation group adopted a customized sphygmomanometer combined with a double-balloon hollow cuff for continuous compression of the forearm hematoma. The cyanosis of the hand, wrist skin temperature, numbness and swelling of the hand, the forearm painand heart rate during the cuff compression of the hematoma, as well as the arm circumference and cuff secondary compression, and direct nursing time of the patients after releasing the cuff compression were compared between the two groups.

Results During the period of cuff compression of hematoma, the cyanosis of hand, wrist skin temperature, numbness and swelling of hand, the forearm pain and heart rate of the observation group were significantly better than those of the control group (P < 0.05); after releasing the cuff compression, the arm circumference and cuff secondary compression and direct nursing time of the observation group were significantly better than those of the control group (P < 0.05).

Conclusion Application of customized sphygmomanometer combined with double-balloon hollow cuff for continuous compression of forearm hematoma can improve patient's comfort degree and cuff compression effect, and reduce nursing workload.
