Preventing dura mater adhesion by continuous irrigation after laminectomy;

8 mm×5 mm dura mater was exposed, and covered with improved chitosan membrane in group A, with sodium hyaluronate in group B, left uncovered in group C.

Methods 45 adult rabbits were established as the experimental models undergoing L5 laminectomy, with 12mm×5mm dura mater exposed.
