Abstract:
A method of protecting tissue and prevention tissue damage 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 polypeptide; polysaccharide, excluding hyaluronic acid having a molecular weight above about 1,500,000; synthetic polymer; or a salt complex or mixture thereof; and B) said polymeric material has a molecular weight of about 50,000 D or above, and the concentration in said aqueous solution of said polymer is 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 surfaces involved in said surgery.
