Abstract:
Objective To establish the animal model of cervical pain induced by formalin injection and explore the effect of cervical pain on cervical vertigo.Methods Formalin of 40 mL/L was injected near the nerve root of left side of neck to establish the model of cervical pain in rabbits.A total of 30 rabbits were divided randomly into two groups.Formalin-induced pain group(15 rabbits): indexes related to the vertebral artery were observed respectively before 2 mL of formalin injection and after it at 5,10 and 30 minutes.Lidocaine-blocking pain group(15 rabbits): pain induced by formalin was blocked by lidocaine of 10 g/L after 15-minute drug administration and the same indexes were observed at the same time and position of the neck.Results In formalin-induced pain group,vertebral artery systolic velocity,diastolic velocity and pulsatility indexes were decreased whereas resistance index was increased(P
