Design outcomes

Primary

Measure	Time frame
Radial artery occlusion. Timepoint: Barbeau test and arterial ultrasound are both performed 24 hours after the study to find the main result. Method of measurement: Radial artery occlusion is measured by Barbeau criterion or arterial ultrasound.	—

Secondary

Measure	Time frame
The amount of heparin. Timepoint: The amount of heparin is measured by the operator during the operation and recorded immediately after. Method of measurement: The operator's heparin usage is pooled and announced by unit.;Prothrombin time. Timepoint: Immediately after the intervention. Method of measurement: Prothrombin time by the Fisher brand laboratory kit.;Partial Thromboplastin time (PTT). Timepoint: Immediately after the intervention. Method of measurement: Partial Thromboplastin time by the Fisher brand laboratory kit.;International unit ratio (INR). Timepoint: Immediately after the intervention. Method of measurement: International unit of dividing pt by the expected amount of the person at the desired age.;Bleeding time. Timepoint: Immediately after the intervention. Method of measurement: Bleeding time by the bt kit of bt-labtatory company.	—
