Summary
A cost-effective gelatin model effectively trained radiology residents in ultrasound-guided fine needle puncture. The simulation significantly improved procedure time and accuracy, boosting physician confidence.
Area of Science:
- Medical Education
- Radiology
- Ultrasound Technology
Background:
- Ultrasound-guided fine needle puncture is a crucial skill for radiologists.
- Effective and affordable training models are needed to enhance procedural competency.
- Current training methods may not adequately prepare residents for thyroid nodule punctures.
Purpose of the Study:
- To assess the efficacy of a novel, inexpensive training model for ultrasound-guided fine needle puncture.
- To evaluate the impact of this training on resident physicians' procedural skills and confidence.
Main Methods:
- A training program involving theoretical instruction and practical simulation using a cost-effective, reproducible model was implemented.
- Twenty resident radiology physicians participated in the study.
- Performance was assessed by measuring procedure time, number of punctures, and confidence levels via questionnaire.
Main Results:
- The gelatin-based model successfully simulated thyroid tissue echotexture and was easy to reproduce.
- Significant reductions in procedure time (p<0.0001) and superficial punctures (p<0.0001) were observed post-training.
- Residents reported subjective improvements in performance and confidence.
Conclusions:
- An inexpensive, easy-to-reproduce gelatin model provides adequate training for ultrasound-guided fine needle puncture.
- This simulation model effectively improves resident physicians' skills and confidence in performing the procedure, even with brief training.
