Surgical Patients Clinical Trial
Official title:
Clinical Research Plan for the Safety and Accuracy of Ultrasound-guided Radial Artery
By observing the anatomical relationship and influencing factors of the radial artery through ultrasound, the optimal puncture location is selected, and puncture catheterization is guided to reduce the number of punctures, reduce complications, and improve safety and accuracy.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Measure the transverse diameter of the radial artery at each anatomical point | The patient is in a flat lying position, with both upper limbs abduction, palms facing upwards, and wrist joint angle of 45 °. A portable ultrasound instrument (probe frequency 13-6MHz, Sono Sound Company) is used, and the ultrasound probe is in vertical contact with the forearm in the short axis direction, Explore the relative anatomical sites of the radial artery (confirmed by Doppler) on the left and right sides of the body surface projection line of the radial artery (from 2.5cm below the center of the cubital fossa to the inner side of the radial styloid process), with a relative distance of 2cm. There is no significant compression of the radial artery during scanning to maintain the normal shape and location of the blood vessels. | Before anesthesia surgery |
