Summary
Contact dermatitis from Bispectral Index (BIS) monitor electrodes is rare. This case highlights the potential for allergic reactions to BIS sensors, similar to those seen with electroencephalography electrodes.
Area of Science:
- Anesthesiology
- Dermatology
- Medical Device Technology
Background:
- Contact dermatitis is an uncommon complication associated with electroencephalography (EEG) electrodes.
- The specific incidence and characteristics of contact dermatitis from Bispectral Index (BIS) monitor electrodes remain poorly understood.
Purpose of the Study:
- To report a case of contact dermatitis attributed to Bispectral Index (BIS) monitor electrodes.
- To raise awareness of potential allergic reactions to BIS monitoring sensors.
Main Methods:
- A case study of a 38-year-old female patient undergoing tooth extraction under general anesthesia with BIS monitoring.
- Clinical observation of post-operative erythema and pigmentation.
- Patch testing to identify specific allergens.
Main Results:
- The patient developed erythema on the forehead three days post-surgery, peaking on the fifth day.
- Post-operative pigmentation was noted at 42 days.
- Patch testing confirmed positive reactions to the BIS sensor and other allergens.
Conclusions:
- Allergic contact dermatitis can occur with Bispectral Index (BIS) monitor electrodes.
- These reactions may be similar to those reported with electroencephalography (EEG) electrodes.
- Clinicians should consider BIS electrodes as a potential cause of contact dermatitis.
