Mathematical substantiation of the main symptoms role in diagnostics of natal injury consequences of the cervical spine

Abstract

Recently, according to the literature, the trauma of the cervical spine in newborns takes the leading place among thenewborn natal injuries. According to available information, out of every 3 births, two newborns are injured in the cervical spine segment during labor. We have studied 136 cases of children who were in the intensive care unit of newborns in Republican Mother and Child Center. As a result of systematization of complaints, disease anamnesis, objective examination, 52 factors related to this disease were collected. The task was to find out the most important factors determining the prognosis of the consequences of the natal trauma of the spine. Algorithm to solve this problem: - study of tables of initial experimental data and measures of tightness of linear regression between factors; - construction, analysis of correlation matrices, splitting of factors into pleiads; - application of expert methods - direct ranking and weighting factors of importance; - tabulation of weakly correlated factors. The mathematical analysis led to reduction of the factor space dimension from the original 49 to 4 units without changing the information capacity. Conclusions: 1. As a result of the calculations, we have established 4 factors containing the greatest information load in the natal trauma of the cervical spine. These factors are the symmetry of the shoulders, the sucking reflex, the weighed gynecological anamnesis, the caesarean section. 2. Based on these four factors, it is planned to construct a probabilistic model for the consequences prognosis of the natal injury of the spine.
