[Effect of local hypothermia on H- and M-responses after spinal cord contusion in dogs]. quadratus plantae in dogs before and after experimental spinal cord contusion with and without following local intraoperative hypothermia.  Our results demonstrate that local hypothermia applied after spinal cord contusion reduces amplitude of both M- and H-responses and also H(max)/M(max) ratio that may indicate depression of motorneurons excitability.  After spinal cord contusion without following hypothermia the excitability of the spinal motorneurons during post-traumatic period, in opposite, was significantly increased.  These results support a conclusion that intraoperative hypothermia after spinal cord contusion can delay development of functional excitability of the motoneurons and protect from further changes in H- and M-responses.
