OBJECTIVES: The exposure to ultrasound technology in medicine is increasing at multiple training levels. Ultrasound transducers have evolved to provide higher-resolution imaging for more accurate structural identification, with few improvements in ease of use. This study investigated a novel finger ultrasound transducer used by first-year medical students conducting structural identification and practicing an invasive procedure.
METHODS: A literature search was conducted on texts, specialty journals, and websites regarding the anatomy of internal jugular and subclavian vein central line placement with sonographic guidance and the use of a finger transducer. First-year medical students performed timed sonographically guided cannulation on the internal jugular and subclavian veins on a phantom torso and identified the internal jugular and subclavian veins on a healthy volunteer using the finger transducer and a conventional transducer. After exposure to both transducers, a survey was taken regarding transducer preference.
RESULTS: The literature search revealed no studies comparing finger and classic transducers or sonographically guided central line techniques being conducted by first-year medical students. The students identified and cannulated the internal jugular and subclavian veins using both transducers. Survey results revealed that 70% of the students preferred the finger transducer.
CONCLUSIONS: This study showed that first-year medical students could interpret sonographic anatomy while conducting a clinical procedure. The finger transducer proved successful in structure identification and was preferred to the classic transducer because of its combined tactile presence. This pilot study of a novel finger transducer showed the benefits of combining palpatory skills with ultrasound technology in teaching first-year medical students to perform invasive procedures.
