Method, Transducer And Needle Selection, And Ergonomics

Method, transducer and needle selection, and ergonomics

The first step in planning an ultrasound guided procedure (after performing limited diagnostic ultrasound) is to properly position the patient. When performing any surgery, keep the patient on his back to avoid the possibility of a vasovagal reaction. Next, plan the general needle approach and transducer plane before marking and cleaning the skin. When performing limb surgery, it is usually necessary to choose to enter the needle along the flat surface or curved surface of the limb. There are several advantages to letting the needle enter along the curved surface, including more working space in the space close to the limbs instead of working directly on the flat surface of the limbs. Another advantage is that the distance between the puncture site and the transducer can be increased. This is helpful because the needle can be more perpendicular to the sound beam (and therefore more conspicuous), and the needle does not directly touch the transducer, depending on the level of aseptic technique.
