Neuropsychological tests can be used to diagnose post-surgery cognitive dysfunction in children. These tests are characterized by attractiveness, accessibility and short duration. Correction tasks, Raven’s matrices, various modifications of words memory tests meet all these requirements. Comprehensive assessment of cognitive functions (including MMSE scale and batteries of computer tests) seems to be optimal.
Background. Surgery under general anesthesia can affect the patients neurocognitive outcome. This problem is of particular relevance in pediatric surgical practice.
Goal. The aim of this study is to determine the spectrum of clinical manifestations and the frequency of cognitive dysfunction symptom development in children after adenotomy and/or tonsillotomy performed under general anesthesia.
Methods. This prospective study included 30 children aged 3 7 years (average age 4.9 1.3 years) who underwent adenotomy and/or tonsillotomy under general, combined, balanced anesthesia. In the preoperative period and a day after the operation, neuropsychological testing was performed: The Raven test, mechanical and associative memory test, Mini-Mental State Examination (MMSE) scale adapted for children from 3 years old, and the Bourdon test. A 20% decrease in function compared with the initial level was considered clinically significant.
Results. One day after surgery, 10% of patients had a clinically significant decrease in attention productivity, 10% had a decrease in attention accuracy, 13.3% had a decrease in attention index, and 16.7% had a decrease in overall productivity and the attention index according to the Bourdon test. Also, 13.3% showed a decrease in attention, 30% had a decrease in memory on the MMSE scale, 20% showed a decrease in mechanical memory, and 10% had a decrease in test results on the Raven test.
Conclusion. Conducting even minor surgical interventions with general anesthesia leads to an impairment of various cognitive functions in 10%30% of children aged 3 to 7 years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
