[The adequacy of patient protection from surgical trauma under spinal anesthesia].
Efficiency of various methods of anesthesia in prevention of the CNS segmented structures hyperreactivity induced by surgical trauma ware studied in 554 patients during planned orthopedic operations and operations on the pelvic organs. Spinal anesthesia played the crucial role in prevention of induced hyperreactivity of nociceptive neurons of the posterior spinal horns. A notable alleviation of postoperative pain in patients operated on under spinal anesthesia was a clinical confirmation of this fact. Analysis of the time course of the amplitudes of the control and test H-reflexes before and after the intervention showed that spinal anesthesia largely prevented perioperative changes in the spinal neuromotor stimulation and, from this viewpoint, can be regarded as the optimal method of anesthesia in surgery on the lower part of the trunk.
