What are the safety issues in ultrasound practice?
Room set-up, equipment maintenance, patient compliance, and bioeffects of ultrasound
What are the bioeffects of ultrasound?
Thermal effects (heating) and mechanical effects (cavitation) on tissues
What do thermal effects of ultrasound depend on?
Power output, frequency, exposure time, field of view, and tissue absorption coefficient
What do mechanical effects of ultrasound, such as cavitation, depend on?
Tissue characteristics, exposure time, pulse duration, and PRF
What does the ALARA principle emphasize in ultrasound practice?
Ultrasound should be medically indicated, with efficient scanning and awareness of safety indices
What does cross-infection prevention in ultrasound practice involve?
Universal precautions, hand hygiene, personal protective equipment, and disposal of sharps and waste
What are the recommended transducer hygiene practices?
Removing gel, wiping with alcohol, using chemical disinfection, and using sterile covers for broken skin and open wounds
What should be done with intra-cavity transducers for TV/TR scanning after procedures?
They should be covered and disinfected
What may work-related musculoskeletal disorders (WRMSD) in ultrasound practice cause?
Persistent pain and discomfort, necessitating attention to ergonomic practices and workplace safety
Why are universal precautions important?
To prevent cross infection
Identify which actions reduce WRMSD (Work-Related Musculoskeletal Disorders):
Allow the patient to lie comfortably
What are the 2 main biological effects of US (Ultrasound)?
Tissue heating and cavitation
If a patient after lying on the bed for an abdominal ultrasound suddenly jumps up and attempts to leave the exam room, what would you do?
Explain the importance of completing the exam and encourage the patient to stay
What are the advantages of US (Ultrasound) vs CT imaging?
Higher resolution and better soft tissue contrast
What are the symptoms of WRMSD (Work-Related Musculoskeletal Disorders)?
Aching, stiffness, burning, pain
What can help prevent WRMSD (Work-Related Musculoskeletal Disorders)?
Ergonomically designed equipment
What should be done if resting arm on patient during scanning?
Seek permission from the patient
