OBJECTIVE: To investigate the clinical effect of @entity7049 membrane in prevention of @entity2318 and adhesion. METHODS: From July 1998 to April 2000, 62 @entity1 with @entity1798 herniation were randomly assigned into two groups. All were treated surgically with discectomy by fenestration or laminectomy. One group were placed with a thin of @entity7049 membrane covering the interlaminar space(n = 32). The thickness of the film was 0.1 mm. The other group was blank control(n = 30). After 2 weeks of operation, we observed the local and systemic reactions. After 6 months clinical symptoms were revaluated and the degrees of @entity2318 and adhesion were determined by CT scans. RESULTS: After 2 weeks, we found no adverse systemic reactions in all @entity1 . Wound healing was excellent. No @entity8 as well as blood for routine were found. Temperature after operation was normal. After 6 months, the curative effects were as follows in experimental group and in control group: excellent in 27 @entity1 and in 24 @entity1 , good in 4 @entity1 and in 4 @entity1 , fair in 1 @entity1 and in 1 @entity1 , and poor in 0 @entity1 and in 1 @entity1 , respectively. There are no significant difference between two groups. The CT scans showed no adhesion between the @entity2318 and the dural sac in all @entity1 of experimental group. There existed various extents of adhesion in control group. CONCLUSION: The results demonstrate that the @entity7049 membrane can effectively prevent the @entity2318 with a good biocompatibility and no toxity. Its clinical application was promising.
