The following issues and situations can affect operator safety when you are using an ultrasound
Repetitive Strain Injury
Repetitive ultrasound scanning has been associated with carpal tunnel syndrome (CTS) and
related musculoskeletal problems. Some investigators have looked at a large population of
sonographers with different types of equipment. An article, with feedback from a smaller
geographical area, makes the following recommendations:
• Maintain your joints in optimum positions with a balanced posture while scanning.
• Allow frequent breaks to give soft tissue a chance to recuperate from awkward positions
and repetitive movement.
• Avoid gripping the transducer with excessive force.
