*************************************************
As MAGIC guideline suggests, with the aid of ultrasound-guided technique, short catheters and midline catheters should be used more often instead of PICCs and CVCs in the case of difficult vascular access.
The dynamic needle tip positioning technique can be applied to ultrasound-guided cannulation of virtually all peripheral vessels, including hemodialysis arteriovenous fistula, upper arm vein for PICC and midline catheter, and radial artery for monitoring. One exception is calcified arteries (e.g., radial artery of dialysis patients): In such cases, the “needle blinking method” may not work because the ultrasound beam does not penetrate the calcified wall.

This is probably the best ultrasound guided access content I've seen. I just wish you had some audio. Great work!

[@Pentamonium]

This essential ultrasound concept is not recognized by many other videos out there.

[@ultrasoundinstructionvideo7767]

Thank you for your kind feedback. I would appreciate it if you could expand the method.

[@JYTS1970]

Dear Tadashi,
Thank you so much for this wonderful resource. Prior to this video, I was struggling to visualise the tip of my needle under ultrasound but now am able to guide the needle (the probe being perpendicular to the needle) the whole journey into the lumen of the vessel. Fan from New Zealand!

[@ultrasoundinstructionvideo7767]

Hi, JYTS1970. Thank you for your kind comment. I'm very glad to be of service.

[@lucyzhang6287]

I always had a problem to visualize the needle tip on the screen, now I know I need to hole the probe tilting a little bit. A great video! Thanks!

[@ultrasoundinstructionvideo7767]

Thank you for your kind comment.

[@isuruabeywickrama1867]

Great explanation. Thank you very much… 👍👏🙏🏿🙏🏻🙏🏻🙏🏻

Very nice.Thanks.

[@hyeoncheolpark9050]

Thank you for this fantastic video

[@ultrasoundinstructionvideo7767]

Thank you for your kind feedback.

[@TheMdmYT]

That was really useful - I will try the orthogonal method

[@ultrasoundinstructionvideo7767]

Thank you for your kind comment. The point
of the orthogonal method is that using a sufficient amount of ultrasound jelly is essential to obtain a good image.

[@mcguigankana]

Thank you for this awesome video. I just got stumped after an annoying failure on a septic pt. Your guide will hopefully improve my technique for the future!

[@ultrasoundinstructionvideo7767]

Thank you for your comment. I'm glad if my video is helpful.

Thanks

[@HassanAlmaateeq]

Thanks. How did you make the phantom?

[@ultrasoundinstructionvideo7767]

The recipe is as follows, but unfortunately, it seems that cuboid konjak is only available in Japan.
1. To make mock vessels, build tunnels through a hard, cuboid konjac jelly by pressing a large straw into it.
2. Place the jelly in a tray whose depth is approximately the same as the thickness of the jelly.
3. Pour water into the tray until the top of the jelly is submerged.
4. Remove the air within the tunnels by squeezing the superior surface of the jelly with fingers.

Where is the sound?

[@ultrasoundinstructionvideo7767]

Sorry, no sound is available. I'll try someday.
