REDUCTION OF POSTOPERATIVE ADHESIONS IN THE RAT UTERINE HORN MODEL WITH POLOXAMER-407

Adjuvants shown to have significant adhesion prevention capabilities have been based on barrier separation of deperitonealized surfaces. We investigated the adhesion prevention properties of poloxamer 407. This polyol, in the proper concentration, is fluid at room temperature and becomes a firm gel at body temperature. The prevention of postoperative adhesions was evaluated in the rat uterine horn model. Twenty-two rats underwent bilateral surgical injury to the uterine horn and the parietal peritoneum. A random side was treated with a 30% solution of poloxamer 407. Twenty-one days later the animals were sacrificed and evaluated for the presence of adhesions. A highly significant reduction in adhesion formation was documented on the treated side. © 1990.
