RESUMEN
A combination of electrical anesthesia with calypsol and nitrous oxide has been developed and used in neurosurgical operations performed to 142 children aged 8 days to 15 years, who were divided into two groups. Group 1 included 89 children administered electrical anesthesia in combination with calypsol and nitrous oxide, Group 2 consisted of 53 children, to whom only routine calypsol and nitrous oxide anesthesia was administered. The Lennar apparatus was used to administer electrical anesthesia. The adequacy of anesthesia was estimated on the basis of the clinical data and laboratory findings. The results have shown that a combination of electrical analgesia with calypsol and nitrous oxide provided sufficient protection of a child from surgical stress, was not associated with significant changes of the hypothalamo-hypophyseo-adrenal and thyroid functions and permitted a significant reduction (by 80.8%) of the drug load.
