Abstract
Objective: To develop an ultrasound-guided internal jugular vein model for residency training
Materials and Methods: The researcher invited seven medical professionals within the Faculty of Medicine Siriraj Hospital who had experience in ultrasound-guided internal jugular vein procedure with real patients and had at least 3 years of teaching and training as resident physicians, aged between 35 - 60 years, to test the performance and features of an ultrasound-guided internal jugular vein model. The objective was to test the properties of silicone rubber suitable for viewing ultrasound images before producing a mannequin. This model consisted of interesting three parts: subcutaneous fat, subcutaneous silicone rubber, skin, and blood vessels. The properties and performance of the model were tested according to the procedure using ultrasound-guided internal venous catheter insertion in the jugular, and a satisfaction assessment form from seven medical specialists was used to evaluate the model.
Results: All seven medical professionals tested the properties of silicone rubber and found that silicone rubber E is suitable for replacing the subcutaneous fat layer, silicone rubber F is suitable for replacing the skin, and J silicone rubber is suitable for replacing blood vessels. The test of the model's properties indicated a level of satisfaction at the "very satisfied" level. The evaluation of the model's effectiveness in the ultrasound-guided internal venous catheter insertion procedure was at the level of satisfaction, ranging from "good".
Conclusion: The researcher has successfully developed a qualified ultrasound-guided internal jugular vein model that can be effectively used for teaching and learning purposes.
