Objective This study compares the utility of palpation-based and ultrasound-guided teaching techniques for subclavian central venous access using formalin-embalmed cadavers. Methods The subclavian veins of 20 formalin-embalmed cadavers were imaged with ultrasound to evaluate vein patency and sonographic clarity prior to venous access. Twenty-three first-year medical students were trained to access the subclavian vein using palpation-based techniques. Training involved ten minutes of didactic orientation and ten minutes of hands-on practical instruction using cadavers. Participant confidence was measured using a 10-point Likert scale on pre- and post-training questionnaires. Objective skills testing for each participant included quantifying the number of skin punctures and recording the time elapsed from skin puncture to fluid flashback into the syringe. Results Participant confidence significantly increased following training in both ultrasound and palpation training groups across all questionnaire items (p p p |
