Abstract
Disclosed are methods for draping a surgical site prior to surgery. Specifically, the methods of this invention involve the in situ formation of a cyanoacrylate polymeric drape on the skin surface of a patient peripheral to the surgical site. Surgery is then conducted at the surgical site.
Claims16
A method for forming an adherent, surface conforming drape peripheral to a surgical site of a patient which method comprises:
- (a) defining a surgical site on the patient;
- (b) applying a sufficient amount of a cyanoacrylate composition comprising polymerizable cyanoacrylate ester monomers and/or oligomers to the skin surface of the patient peripheral to the surgical site defined in (a) above;
- (c) polymerizing the cyanoacrylate ester so as to form a flexible, waterproof, adhesive polymer layer which adheres to the area(s) where the composition was applied;
- and
- (d) conducting surgery on the patient at the surgical site defined in (a) above.

A method for forming an adherent, surface conforming surgical incise drape peripheral to a surgical site of a patient which method comprises:
- (a) defining a surgical site on the patient;
- (b) applying a sufficient amount of a polymerizable cyanoacrylate composition comprising polymerizable cyanoacrylate ester monomers and/or oligomers onto the skin surface peripheral to the surgical site defined in (a) above wherein the polymerizable cyanoacrylate ester, in monomeric form, comprises:
- (i) polymerizable n-butyl cyanoacrylate which, in monomeric form, is represented by formula II:
- ##STR5## (ii) from 18 to 25 weight percent of dioctylphthalate based on the total weight of the composition absent polyvinylpyrrolidone iodine;
- (iii) from 5 to 40 weight percent of polyvinylpyrrolidone iodine based on the total weight of the composition;
- (c) polymerizing the cyanoacrylate composition thereby forming a flexible, waterproof, adhesive polymer layer which adheres to the area(s) where the composition was applied;
- and
- (d) conducting surgery on the patient at the surgical site defined in (a) above.
