Abstract
An improved method and composition for preventing adhesions during surgery. Tissue surfaces and surgical articles involved in the surgery are coated with a solution of a hydrophilic, polymeric material prior to manipulation of the tissue during surgery. The composition comprises a solution of a polymeric material having a molecular weight of about 500,000 or above having a concentration of from about 0.01 to about 15%, by weight.
Claims5
A method of preventing post-operative surgical adhesions of tissue in surgery comprising providing surfaces involved in said surgery with a wet coating of a physiologically acceptable aqueous solution of a hydrophilic, polymeric material prior to manipulation of said tissue during said surgery wherein (A) said polymeric material is a water-soluble, biocompatible, pharmaceutically acceptable member selected from the group consisting of PVP, polyethylene glycol, poly-dimethylacrylamide, salts thereof, complexes thereof and mixtures thereof;
- and (B) said hydrophilic, polymeric material (1) has a molecular weight of about 500,000 or above, and (2) has a concentration in said aqueous solution in the range of from about 0.01% to about 15% by weight, said molecular weight and concentration having values such that said aqueous solution is capable of providing wet coatings on said tissue.
