RESUMO
There are many contradictory data available in the literature on the trends of diagnosed congenital malformations, including those requiring emergency treatment in neonatality. An examining specialist must make use of the algorithm to determine the condition of a neonate, which allows him to qualitatively define the time of surgical treatment and to predict the further course of disease, including its postoperative course. Problems can be solved in the context of evidence-based medicine. To compare the degree and causes of the critical condition of neonatal infants with developmental malformations, the authors have developed a severity rating scale for the newborn with developmental malformations at a gestational age of 35 weeks and a body weight of more than 2 kg, treated at an intensive care unit, by using the results of clinical, laboratory, and morphological studies and estimating the scores. Infants with esophageal atresia, diaphragmatic hernia, anterior abdominal wall and intestine were used as an example to determine changes and causes of the severity of neonates before and after surgery, by taking into account their scores.
