Ifosfamide extravasation.

OBJECTIVE

To report a case in which a local reaction is attributed to an ifosfamide extravasation. Previously, extravasated ifosfamide has been considered a nonirritant.

CASE SUMMARY

A 54-year-old woman with a non-Hodgkin's lymphoma in stage IV B developed a local reaction in her right arm after an ifosfamide extravasation. No pressure was prescribed, no bandaging was applied on the affected area, and the limb was elevated to the heart level. In addition, chondroitinsulfatase 150 turbidity-reducing units was administered subcutaneously around the area. This procedure was repeated 12 hours later, resulting in a satisfactory decrease in the inflammatory signs and pain.

DISCUSSION

The local reaction in the patient's arm cannot be attributed to the hypertonicity of the infusing solution or to the vehicle of the infusate. The antidote used was chondroitinsulfatase, an enzyme similar to hyaluronidase. It enhances the systemic uptake of the drug from the tissue.

CONCLUSIONS

Extravasated ifosfamide is a potential irritant. General measures applied after its extravasation can be potentiated strongly by local subcutaneous administration of chondroitinsulfatase or hyaluronidase, repeated if necessary.
