Objective. To evaluate a new haemostasis method using an ultrasound probe to compress the radial artery and haemostasis under direct vision to replace traditional manual compression of the radial artery. Methods. According to a random number table, 240 patients with gastrointestinal tumours who had undergone arterial puncture were divided into Group A (120 cases) and Group B (120 cases). In Group A, patients were under the guidance of ultrasound to confirm the vascular port, determine the compression position of the ultrasound probe, observe the degree of vascular deformation, and press the radial artery puncture port with pressure to stop bleeding under direct vision. In Group B, traditional manual compression was used. All patients received 5 min of compression for haemostasis, and haemostasis conditions were recorded after compression and 24 hours postoperatively. Results. The incidence of bleeding, haematoma, and skin ecchymosis at the puncture site after 5 minutes of compression in Group A was lower than that in Group B ( P < 0.05 ). No significant difference was found between the two groups at 24 hours after the operation ( P > 0.05 ). Conclusion. The method using an ultrasound probe to guide radial artery compression to haemostasis is better than traditional manual compression when applied for compression haemostasis after removing the radial artery catheter.
