When there is risk of extravasation taking place the patient will be seen by a plastic surgeon who will perform a number of different methods depending on the progress of the extravasation. The first stage that will be taken if the problem is not yet severe will be the monitoring of the extravasation.
If the problem becomes severe the main option to help is a saline washout which uses chemicals to try and reverse the extravasation. Often extravasation will result in sensitivity, colour change and swelling to the tissue damaged, if any of these symptoms occur a referral must be made to a plastic surgery team.
Due to limited research on the matter of extravasation there is little that can be done after it has taken place other than to deal with the issue of the damaged tissue post-extravasation.
