Abstract: Objective  To investigate the clinical characteristics in patients with severe heat stroke. Methods  Patients with severe heat stroke were grouped by combining whether or not rhabdomyolysis and  peripheral nerve damage. Furthermore， the specific features of peripheral nerve damage were analyzed by electromyography. Results  The proportion of nerve damage in patients with severe heat stroke was 40.9%. Patients combined with rhabdomyolysis had a higher proportion of nerve damage up to 71.4%(P<0.05). The electromyography of the median nerve， ulnar nerve， tibial nerve and common peroneal nerve in patients with nerve damage showed that both sensory nerve conduction velocity and motor nerve conduction velocity decreased significantly (P<0.05). Conclusion  The patients with severe heat stroke had a high proportion of peripheral nerve injuries， and the sensory and motor nerve conduction velocity decreased significantly.
