[Stress analgesia in experimental burn shock].

Experiments with curarized and slightly anesthetised adult cats with burn shock have demonstrated pronounced depression of excitation transmission in associative and nonspecific afferent systems during somatic, sound and light stimulation. Effects controlling the activity of the cardiovascular system were facilitated in efferent systems. In white rats, burn shock led to an increase in the somatic and visceral pain threshold during the first 5 days.
