Parameters of physical development of term newborns with Intrauterine Growth Retardation, born in a 3B Level Perinatal Centre of St. Petersburg State Pediatric Medical University in 2022

Abstract

BACKGROUND: Intrauterine growth retardation of a newborn child is an current problem in neonatology, obstetrics and pediatrics. Due to intrauterine development disorders, these newborns have increased morbidity and mortality rates. In the presence of Intrauterine growth retardation, the likelihood of developing complications in the early neonatal period increases (birth asphyxia, meconium aspiration, hypoglycemia, polycythemia, etc.), and the risk of developing infections and neurological disorders) is increased. AIM: The aim of this study is to study the parameters of physical development of term newborns born in the Perinatal Centre 3B level of the St. Petersburg State Pediatric Medical University in 2022 year, to determine the frequency and structure of disorders associated with Intrauterine growth retardation and malnutrition depending on the gestational age of term newborns for a differential approach in the management of children with Intrauterine growth retardation by neonatologists and paediatricians. MATERIALS AND METHODS: There were analyzed 1000 hospital neonatal records of newborns children born at the Perinatal Centre of Level 3B of St. Petersburg State Pediatric Medical University in 2022 year. Of these, 55 term babies were born with Intrauterine growth retardation. The study examined the physical development of term newborns, determined the frequency and structure of disorders associated with intrauterine growth retardation and malnutrition, depending on the gestational age of term newborns. RESULTS: Retardation of intrauterine growth and development in newborn children born in level 3B centres are represented by low body weight in relation to gestational age in 63.6% of cases, trophic disorders with normal body weight and reduced weight/length ratio in 34.6% of cases, and low height index with normal body weight in 1.8% of cases. Severe physical developmental disorders were found only in children with low body weight: in 13% of cases of low birth weight for gestational age, and in 55% of cases of small fetal size for gestational age. CONCLUSIONS: the distribution of physical development disorders (ICD code P05.2) in term infants, depending on the degree of maturity has a linear trend and occurs with maximum frequency (50%) in late term newborns, which is associated with the onset of aging of the placenta and the intensification of existing, even compensated, placental insufficiency.
