Abstract:
Objective To explore the effect of the ropivacaine combined with sufentanil on neuropathic pain in rats.Methods The constriction injury method was performed to establish rat neuropathic pain model and 40 neu-ropathic rats were produced in accordance with the above modeling methods,which were divided into group A(ropiva-caine and sufentanil combined administration,n =10),group B(ropivacaine administration,n =10),group C(sufen-tanil administration,n =10)and group D(no administration,n =10).A total of 10 healthy rats without any treatment, the normal feeding,named as group E.At 1,3,7,11,14,21d after operation von -Frey filaments determination of mechanical hyperalgesia(MWT),and the Hargreaves method for the determination of thermal hyperalgesia(TWL) were measured and the ELISA Kit (IL -6 and TNF -α) were used to detect serum IL -6 and TNF -αconcentrations.Results Before and at 1 day after the operation mechanical allodynia and thermal hyperalgesia and allergy treatment had no significant difference(all P >0.05).Mechanical allodynia and thermal hyperalgesia of group A,B and C were significantly lower than those before the treatment and at 1 day after operation(all P <0.05),and mechanical hyperalgesia and thermal hyperalgesia of group A was significantly lower than those of group B and C (all P <0.05).The serum IL -6 and TNF -αconcentrations of 7,14 and 21 days in group A were significantly lower than those of group B and C(t =7.10,5.84,9.11,all P <0.05).Conclusion The effects of ropivacaine combined with sufentanil analgesic on neuropathic pain of rats was significantly higher than that of ropivacaine or sufentanil alone in the treatment.
