The appearance and concealment of puncture needle under ultrasound

With the continuous popularization of ultrasound equipment, more and more clinical medical staff can use ultrasound to carry out visualization work. People who say they don't know how to do ultrasound-guided puncture are embarrassed to say hello to their peers. However, from the author's observation of some clinical use, the popularity of ultrasound equipment and ultrasound visualization can not be directly equated. In the case of ultrasound-guided puncture in the area of vascular access, many people are actually in the stage of pretending to understand, because even though there is an ultrasound, you can't see where the needle is. In true ultrasound-guided puncture technology, the first thing is to ensure that the position of the needle or tip can be seen under ultrasound, rather than making a rough estimate, and then "blind penetration" under ultrasound guidance. Today we will talk about the appearance and concealment of the piercing needle under ultrasound.

Ultrasound-guided puncture is generally divided into in-plane puncture and out-of-plane puncture. In the field of vascular access, both puncture techniques have applicable scenarios, and it is best to master them. The following is an excerpt from the Practice Guidelines for ultrasound-guided vascular access Surgery of the American Academy of Ultrasonic Medicine that describes both puncture techniques.
