Abstract

Abstract : Background and aims: Advancement in ultrasononography has increased the interest among anesthesiologists to learn regional anesthesia techniques. Commercially available phantom models like gelatin based phantom and agar based phantoms, though inexpensive, have a shorter shelf life. We devised a novel and cost effective learning phantom using I gel for needling training using ultrasound-guided (USG) with good visibility of needle. Methods: I gel is placed over a flat surface and the hollow of the I gel is filled with transparent jelly and both sides of I gel is closed using adhesive tape (figure 1 ).The USG probe is placed longitudinally along the long axis of I gel just proximal to the non-inflatable cuff (figure 2 ). This will create a hyperechoic linear artefact which simulates the target on the sonoimage (figure 3 ). The 16G needle is placed near the USG probe at around a 30-degree angle to the surface of I gel and try to pierce the I gel and the needle will pass smoothly through the I gel surface. Results: You will find the entire length of needle passing through the I gel and a linear hyperechoic line will be seen as the target. This will create a real time simulation of parenchymal tissue. Needling can be repeated several times without damaging the I gel. Conclusions: I gel phantom can be a cost effective and durable training phantom for learning needle manipulation under USG guidance especially for novice interested in USG guided peripheral nerve blocks.
