Contact Dermatitis
|September 1, 1987
Summary
Allergic contact dermatitis can occur after ultrasound procedures due to conducting gels. Patch testing confirmed the allergy, with propylene glycol identified as a cause in some cases.
Area of Science:
- Dermatology
- Medical Device Materials Science
Background:
- Ultrasound investigations are common diagnostic procedures.
- Conducting gels are essential for ultrasound imaging.
- Allergic reactions to medical materials are a growing concern.
Observation:
- Four patients presented with allergic contact dermatitis following ultrasound examinations.
- The dermatitis appeared after the patients underwent ultrasound investigations.
Findings:
- Patch testing revealed positive reactions to the conducting gels used during ultrasounds.
- Propylene glycol was identified as the causative agent in two of the four patients.
- Similar allergic reactions to gels are documented in electrographic and transcutaneous electrical analgesia practices.
Implications:
- Healthcare providers should be aware of potential allergic reactions to ultrasound gels.
- Further investigation into the hypoallergenic properties of conducting gels is warranted.
- Consideration of alternative conducting agents may be necessary for sensitive individuals.
