Summary
Preclinical medical students gained significant confidence in vascular access procedures after a novel ultrasound-guided cadaver training program. This accessible training improved understanding of anatomy and clinical ultrasound use.
Area of Science:
- Medical Education
- Surgical Skills Training
- Point-of-Care Ultrasound
Background:
- Preclinical medical curricula often lack comprehensive training in advanced ultrasound-guided vascular access.
- Limited exposure hinders student proficiency in essential procedural skills.
- Developing effective teaching methods for vascular access is crucial for early medical training.
Purpose of the Study:
- To evaluate the impact of a novel ultrasound-guided cadaver-based training program on preclinical medical students' confidence.
- To assess improvements in understanding vascular anatomy and clinical ultrasound application.
- To determine the efficacy of cadaver labs in teaching complex vascular access techniques.
Main Methods:
- A cohort of 15 preclinical medical students participated in an ultrasound-guided cadaver-based vascular access training program.
- Confidence scores were assessed using pre- and post-training surveys.
- The training focused on femoral, radial, and internal jugular catheterizations.
Main Results:
- Significant increases in confidence were observed across all assessed areas post-training (P < .05).
- Students reported enhanced understanding of vascular anatomy.
- Confidence in clinical ultrasound use and performing specific catheterizations improved markedly.
Conclusions:
- Ultrasound-guided cadaver-based training is an effective and accessible method for teaching vascular access skills to preclinical medical students.
- This approach significantly boosts student confidence in procedural competency.
- Cadaver training offers a promising avenue for enhancing procedural skills education in early medical training.
