- Abstract
Objectives The purpose of this study was to examine the feasibility of an optical see-through head-mounted display (OST-HMD) to improve ergonomics during ultrasound-guided fine-needle aspiration (FNA) in the neck region. Methods This randomized controlled study compared an OST-HMD with a normal ultrasound monitor during an ultrasound-guided FNA in the neck region. Patients with a neck tumor were recruited and randomized into one of two groups. Two practitioners performed ultrasound-guided FNA with or without the HMD, as indicated. An independent researcher measured the procedure time, the number and time of head movements, as well as the number of needle redirections. In addition, practitioners completed questionnaires after performing the FNA on each patient. Results In 93% of the sessions with the OST-HMD, practitioners performed ultrasound-guided FNA without turning the patients' heads. There was no difference in procedural time and number of needle redirections between the two groups. Results from the questionnaire revealed not only good wearability and low fatigue, but also the practitioners' preference for the HMD. Conclusions The OST-HMD improved the practitioners' ergonomics and can be adopted for performing ultrasound-guided interventional procedures in clinical settings.
