Abstract

Abstract The present invention provides a method for treating burns. The method includes injecting an effective amount of a surface-active copolymer into a human or animal with a burn. The surface-active copolymer can be an ethylene oxide-propylene oxide condensation product with the following general formula: HO(C2H4O)b(C3H6O)a(C2H4O)bH where a is an integer such that the hydrophobe represented by (C3H6O) has a molecular weight of approximately 950 to 4000, preferably approximately 1200 to 3500, and b is an integer such that the hydrophile portion represented by (C2H4O) constitutes approximately 50% to 90% by weight of the compound.
