Effects of Postoperative Methycobal Administration on Digital Replantation Based on Stellate Ganglion Stimulation

To study the impact of stellate ganglion block (SGB) on digital replantation and analyze its mechanism. Digital arterial diameter was enlarged after SGB, and the difference in the survival rate of severed finger after replantation was not statistically significant between the two groups (P>0.05). Through the treatment with Methycobal, the recovery of 2-point discrimination (2-pd) of the experimental groups (A, B) was significantly better than that of the negative control group, between which the difference was statistically significant (P<0.01 between Groups A and C, P<0.05 between Groups B and C), indicating that the methyl vitamin B 12 can significantly promote the regeneration of peripheral nerves. Methycobal is of great significance to the postoperative treatment of digital replantation, which is worthy of being widely applied in clinic practice.
