be used. (Latex gloves labeled “Hypoallergenic” may not always prevent
adverse reactions.)
• Whenever latex-containing medical devices are used, especially when the
latex comes in contact with mucous membranes, be alert to the possibility
of an allergic reaction.
• If an allergic reaction does occur and latex is suspected, advise the patient
of a possible latex sensitivity and consider an immunologic evaluation.
• Advise the patient to tell health professionals and emergency personnel
about any known latex sensitivity before undergoing medical procedures.
Consider advising patients with severe latex sensitivity to wear a medical
identification bracelet.
The FDA is asking health professionals to report incidents of adverse reactions
to latex or other materials used in medical devices. (See the October 1990 FDA
Drug Bulletin.) To report an incident, call the FDA Problem Reporting Program,
operated through the U.S. Pharmacopoeia toll-free number: 800-638-6725. (In
Maryland, call collect 301-881-0256.)
For a single copy of a reference list on latex sensitivity, write to: LATEX, FDA,
HFZ-220, Rockville, MD 20857.
NOTE
The ultrasound system and transducers described in this document do not
contain natural rubber latex that contacts humans. Natural rubber latex is not
used on any Philips ultrasound transducer. It also is not used on Philips ECG
cables for the products described in this document.
ALARA Education Program
The guiding principle for the use of diagnostic ultrasound is defined by the "as
low as reasonably achievable" (ALARA) principle. The decision as to what is
reasonable has been left to the judgment and insight of qualified personnel. No
set of rules can be formulated that would be sufficiently complete to dictate the
correct response to every circumstance. By keeping ultrasound exposure as low
as possible, while obtaining diagnostic images, users can minimize ultrasonic
bioeffects.
