Traditional anatomical landmark technique for vascular cannulation, have been a
source for various failures and complications.

On the other hand, ultrasound-guided vascular cannulation has been shown to improve
first pass success, reduce the number of attempts, improve patient’s satisfaction
and reduce overall procedure-related complications.

### ** Which ultrasound scanner is best for vascular cannulation? **

Since vascular structures are superficial, a linear array transducer (7–10MHz) [SIFULTRAS-5.34](https://sifsof.com/product/linear-wireless-ultrasound-scanner-sifultras-5-34/)
is commonly used to recognize the vessels, with the selection of a preset corresponding
to veins or arteries, as the case may be.  

Ultrasound-guided vascular cannulation is becoming the modality of choice to obtain
tool to obtain a secure vascular access in critical care patients.

 Depth, gain and focal zones are the most important machine parameters that practitioners
always need to optimize to carry out the best possible evaluation on the vessels.
Preferably, tissue harmonic imaging must be switched off, especially for further
needle recognition.

Nonetheless, to summarize and simplify the fundamental sonographic aspects at the
moment of deciding and executing an ultrasound-guided vascular access, and it also
intends to highlight some aspects related to the optimal training for this practice.
It goes as follows;

 After recognizing the vascular structures, the next step is selecting an adequate
vessel to be successfully cannulated In all cases, the selected vessel must be permeable,
must be as superficial as possible, and have a secure pathway regarding the predicted
travel of the needle, avoiding possible damage of key structures.

 Once a target vessel is selected, cannulation can be executed using an static technique
or using a dynamic or real-time technique, consisting in observing the screen for
direct or indirect signs of the needle entering into the vesse. Both US techniques
are more successful for cannulation in comparison with the landmark technique.

Ultrasound guidance can be used for placing central venous catheters as well as 
for placing peripheral venous catheters. Clinicians who place central venous access
devices (occasionally or frequently) are strongly encouraged to learn ultrasound-
guided techniques.
