METHOD FOR ASSESSING ADEQUATE GENERAL ANAESTHESIA IN CHILDREN AGED FROM 4 TO 14 YEARS OLD BY LONG-LATENCY AUDITORY EVOKED POTENTIALS Russian patent published in 2014 - IPC A61B5/476 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to anaesthesiology, and may be used in assessing an adequate general anaesthesia in the children aged from 4 to 14 years old. That is ensured by pre-anaesthetic and intra-anaesthetic intraoperative recording of long-latency auditory evoked potentials. That is followed by summing up initial latencies of first three pre-anaesthetic peaks (P1, N1, P2) to calculate sum A, subtracting the sum of the latencies of the first three intraoperative peaks (P1, N1, P2) to calculate sum B. The A to B relation is multiplied by 100. A percentage of the latencies of the intra-anaesthetic peaks P1, N1, P2 to the pre-anaesthetic values is considered as the adequate general anaesthesia. For the children of the first age group of 4-6 years old, the general anaesthesia is considered to be adequate, if the percentage is 140-253%; for the children of the second age group of 7-9 years old, the adequate general anaesthesia is shown by the percentage of 133-253%; for the children of the third age group of 10-12 years old, the adequate anaesthesia is shown by the percentage of 159-190%; and the percentage of 125-271% provides the adequate general anaesthesia for the children of the fourth age group of 13-14 years old.

EFFECT: method provides the adequate and easy assessment of the anaesthesia ensured by reducing a time of examination and simplicity of data interpretation in the form of one three-peak wave.
