Use of portable ultrasound for ultra-sound guided regional anesthesia

Regional anesthesia is now frequently superior to general anesthesia for many different surgeries like for instance out-patient surgery, orthopedic surgery and also in improving the overall quality of post-operative analgesia.
When making peripheral nerve blocks it is necessary to inject the local anesthetic in close vicinity of nerve trunks in order to interrupt the nerve impulses. Safety requires the ability to avoid injecting intraneurally and intravascularly and to reduce the injected doses.
Ultrasound-guided regional anesthesia has allowed reaching the safety standards as never before. When using ultrasound-guidance the anesthesiologist is able to identify the various anatomical structures and thus adapt the procedure to inter-individual anatomy. Furthermore, ultrasound-guidance allows real-time needle guidance and assessment of local anesthetic spread around neural structures. Visualizing the spread of local anesthetic allows a rapid and early diagnosis of intraneural or intravascular injection as well.
Ultrasound-guidance therefore decreases the number of vascular punctures as well as reduces the injected volumes, while increasing the overall success rate of peripheral nerve blocks. Moreover, ultrasound-guided regional anesthesia improves patient comfort.

The ultrasound scanners EXAGO andEXAGYNE are perfectly well adapted for use in ultrasound-guided regional anesthesia: a high-quality image and all the standard imaging modes B, CFM, PW and M, concentrated in a small volume. EXAGO and EXAGYNE are ultra-mobile devices, very light-weight and working with a long-lasting battery.

EXAGO, the ultra-portable scanner weighs only 3.2 kg and boots up in 20 seconds/ It provides a high-quality image with an excellent contrast and also both colour Doppler and Pulsed Wave. EXAGO works on a battery with an excellent autonomy that enables you to work for more than 5 hours in the operation theatre without any concern about electricity.

EXAGYNE, the portable scanner, makes the work of the anesthesiologist a lot easier: a very good image quality, a good Doppler with a remarkable sensibility and specific and user-friendly presets for all different types of blocks. The more advanced functions like trapezoidal image and two types of zoom are appreciated by anesthesiologists working with ultrasound-guided regional anesthesia.
