Needle | FUJIFILM Sonosite

The video introduces the use of vascular access ultrasound as an adjunct for peripheral vein access, particularly useful in cases where standard palpations may not suffice due to factors like arm edema or obesity. The linear array transducer is selected for its high-frequency imaging capabilities suited for superficial structures like veins. The Venous preset is chosen, and examination begins at the antecubital fossa, where a superficial vein is easily identified. Adjustments are made for depth and gain to optimize visualization. Deeper veins such as the brachial and basilic veins are also examined, with emphasis on catheter size selection and precautions against catheter dislodgement. The presence of arteries and nerves in proximity to veins is noted, informing decisions on optimal cannulation sites to avoid complications.

How To Perform A Supraclavicular Nerve Block

The Sonosite SII ultrasound machine supports regional anesthetic techniques used during supraclavicular blocks – serving as an alternative or adjunct to general anesthesia needed for postoperative pain control for upper extremity surgeries (mid-humerus through the hand). Anesthesiologist Dr. David Auyong MD of Seattle, Washington here reviews scanning techniques and sonographic landmarks for the ultrasound guided nerve block. Dr. Auyong highlights patient position, the type of transducer used, the needle position and injection technique. The ability to image the plexus, rib, pleura, and subclavian artery increases safety due to improved monitoring of anatomy and needle placement.
