A Novel Plant Based Ultrasound Phantom [PDF]

Journal of Anaesthesia and Critical Care Reports, 2020
Introduction In most of the ultrasound guided regional anaesthesia workshops, anaesthesiologists usually concentrate on identification of nerves & plexus on human volunteers and practice needling techniques on phantom. Proper needle insertion technique and correct manipulation are two important skills for ultrasound-guided peripheral nerve blocks.
