ANATOMICAL POSSIBILITIES OF ACCESS TO AND BLOCKADE OF N-FEMORALIS IN THE DOG

The anesthesia (blockade) of canine n, femoralis may be performed eith er from lumbar or inguinal region. The insensibility of skin in the me dial part of the thigh, tibia and tarsus as well as the akinesia of m, quadriceps femoris are attained by the anesthesia. The blockade of n, femoralis from the lumbar region often attains n. obturatorius as wel l. If the blockade of n femoralis and n, ischiadicus was performed at the same time, almost all muscles of the hind limb (except m. pectineu s, m. gracilis, n. obturatoris internus and m. adductor) would be inac tivated which may considerably facilitate minor:surgical and postopera tive. interventions on the canine hind leg. Acces to femoral nerve fro m lumbar can be recommended because of better results and easier perfo rmance and after the aplication of anesthetic the effect is faster and more efficient. The signs of the obturator nerve blockade were obtain in some dogs especially in dogs with long legs.
