An experimental study on injured peripheral nerves repaired by adhesion of fibrin glue / 中国微创外科杂志

ABSTRACT

Objective To compare the effects of fibrin glue adhesion or epineurium suture on repairing injured peripheral nerves. Methods 20 male rats were randomly divided into two groups group fibrin glue adhesion (n=10) and group suture (n=10). Left sciatic nerves of rats were made repaired nerves models. The nerves of 8 rats in each group underwent electrophysiological and histological examination at the 8th week postoperatively. The nerve specimens of other 2 rats in each group were examined under transmission electron microscope. Results Nerve fibers alignment in group adhesion was more regular than that of group suture at the 8th week after operation. There were significant differences in delayed ratio of latency of motor nerve, nerve fibers cross ratio, recovery ratio of sectional area of myelinated fibers and recovery ratio of muscle wet weight between the two groups( t =2 32, P =0 032; t =2 43, P =0 029; t =2 39, P =0 030; t =2 36, P =0 031). Conclusions Adhesion of fibrin glue for the repair of injured peripheral nerves is an effective method.
