GETTI
NG STARTED
Transrectal access
Examinations should be performed with more cautions because heating of
the transducer has the potential to produce additional heat to adjacent tissue.
The ALARA principle should be observed when adjusting controls that affect
the acoustic output and transducer dwell times should be considered.
Intraoperative and Laparoscopic access
Laparoscopic ultrasound-related morbidity is low and has been reported to
range between 0% and 4%.
Equipment cleaning and disinfection should be performed according to
institutional/hospital approved infection-control guidelines utilizing vendor-
recommended disinfection products.
Ultrasound transducers used in image-guided interventional procedures are
generally classified as semi-critical items (objects that come into contact with
mucous membranes or skin that is not intact). Direct transducer contact with
critical medical products should be avoided during the procedure despite the
use of sterile, disposable transducer covers. Critical medical products, which
include ultrasound transducers that are used intraoperatively, or through
which a needle will be introduced (e. g. for abscess drainage or PTCD) must
be sterilized. After every examination, residual US gel should be carefully
removed with a disposable towel and the transducer cord wiped with a towel
moistened with cleanser, followed by disinfection with a virucidal agent. The
sterilization process should always conform to standard operating
procedures.
The ALARA principle should be observed when adjusting controls that affect
the acoustic output and transducer dwell times should be considered.
Neonatal
During neonatal diagnostic ultrasound examinations capillary hemorrhaging
in lung may occur in neonates, especially if they are pre-term.
Ultrasound exposure of the neonatal brain may lead to a significant
temperature elevation at the bone-brain, which can potentially alter neuronal
structure and function and affect behavioral and cognitive function.
The ALARA principle should be observed when adjusting controls that affect
the acoustic output and transducer dwell times should be considered.
