Abstract:Objective After transradial angiography, based on the non-invasive blood pressure of the patient's healthy upper limb after surgery, the adjustmenf of the pressure value of the radial artery hemostat airbag can achieve both hemostasis and reduce the occurrence of finger swelling on the puncture side, improve the patient's comfort. Methods A total of 274 postoperative patients received coronary angiography at Nanjing Jiangbei Hospital from February to November 2022 were selected and randomly divided into control group and observation group (n=137, each). The control group was adjusted by instructions of the radial artery hemostat, while the observation group adjusted the hemostatic pressure of the radial artery hemostat balloon based on the non-invasive arterial blood pressure value of the patient's healthy upper limb. The situation of hand swelling, bleeding, and patient pain scores in both groups of affected limbs were observed. Results The degree of swelling, bleeding, and pain in the affected limbs and hands of the observation group was better than those of the control group (P＜0.05). Conclusion After transradial angiography, adjusting the hemostatic pressure value of the radial artery hemostatic balloon according to the non-invasive arterial blood pressure value of the patient's healthy upper limb at different time periods can reduce the degree of hand swelling, bleeding and pain in the affected limb.
