The aim of the study was to assess the level and depth of various types of anesthesia by studying the BIS-index in intraocular operations in children.
The data of the study of the dynamics of the BIS-index and, accordingly, the depth of sedation indicated the effectiveness of the anesthesia options used, including the use of inhaled anesthetics sevoflurane and isoflurane in the anesthetic support of intraocular operations. The following combinations were used to provide anesthetic protection in 46 children with intraocular surgery: fentanyl with sevoflurane (group 1), fentanyl with isoflurane (group 2). At the stage of basic anesthesia in patients of group 1, the BIS index was in the range of 45,8-57,4, in group 2, the BISindex was in the range of 37,61- 53,6.
All the proposed options of anesthesia provide a sufficient level of sedation of patients during intraocular operations and can be used in practice. Thus, conducting anesthesia using BIS-monitoring allows you to reduce the doses of drugs used, reduce the amount of excessively deep and superficial anesthesia, and reduce the time of recovery of consciousness after the end of the operation
