Sugary band-aid may help heal post-operative tissue
Date:5/31/2010

NEW YORK (May 31, 2010) -- A compound found in sunless tanning spray may help to heal wounds following surgery, according to new results published by plastic surgeons from NewYork-Presbyterian Hospital/Weill Cornell Medical Center in New York City and biomedical engineers at Cornell University in Ithaca, N.Y., where the novel compound was developed.

Results published today in the Proceedings of the National Academy of Sciences show that a sticky gel composed of polyethylene glycol and a polycarbonate of dihydroxyacetone (MPEG-pDHA) may help to seal wounds created by surgery.

Procedures to remove cancerous breast tissue, for example, often leave a hollow space that fills with seroma fluid that must typically be drained by a temporary implanted drain. "This is an unpleasant side effect of surgery that is often unavoidable," explains Dr. Jason Spector, co-author of the study and plastic surgeon at NewYork-Presbyterian Hospital/Weill Cornell Medical Center.

The gel could potentially be used in all different reconstructive surgeries to prevent seroma formation. "The new substance would act to glue together the hole left behind to prevent seroma buildup," says Dr. Spector.

DHA is a compound that sticks to compounds in biological tissues, called amines. The sticky properties of DHA are what allows sunless tanner to adhere to the skin without being wiped off. However, it is biodegradable and water soluble as well, which means that the compound does not stay tacked onto the body's tissues forever. Currently used "bio-glues" are made from animal products and take a long time to degrade in the body -- both factors that raise the risk of infection.

"DHA is a compound that is naturally produced in the body," explains Dr. David Putnam, the study's senior author and a biomedical engineer from Cornell University's Department of Biomedical Engineering and School of Chemical and Biomolecular Engineering. "The glue is broken do
