Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Measure the anatomical parameters of the radial artery and radial nerve in the forearm using ultrasound, summarize the relevant anatomical factors that affect the placement of radial artery catheterization, and find the optimal puncture range that is both safe and accurate for radial artery catheterization.

A total of 100 surgical patients were included. Ultrasound was used to measure the transverse diameter (TDA) of the radial artery, the vertical distance (VDA) between the radial artery (center) and the skin, and the distance (D) between the superficial branch of the radial nerve and the radial artery at the midpoint between the radial styloid process point, 2.5cm, 5cm, 7.5cm, 10cm from the radial styloid process point, 2.5cm below the center of the elbow fossa, and 10cm from the radial styloid process point and 2.5cm below the center of the elbow fossa. The radial artery was compared on both sides of the patient, as well as on different genders and ages Differences in anatomical parameters and spatial relationships of the radial nerve. Patients were randomly divided into a distal group (Group A, 33 cases), a mid distal group (Group B, 33 cases), and a proximal group (Group C, 33 cases). Group A underwent radial artery puncture and catheterization within 0-5cm of the proximal end of the radial styloid process; Group B underwent radial artery puncture and catheterization within 5-10cm of the proximal end of the radial styloid process; Group C underwent radial artery puncture and catheterization within a range of 10cm proximal to the styloid process of the radius and 2.5cm below the center of the cubital fossa. The success rate, puncture time, puncture frequency, and puncture related complications of the first ultrasound-guided radial artery puncture and catheterization were recorded for three groups of patients.
