This retrospective study aims to analyze the relationship between biochemical changes occurring in newborns with sepsis proven by positive blood culture (BC) and possible correlations with 1 min Apgar score, 5 min Apgar score, gestational age (GA), and birth weight (BW). We included in the study all infants ≤7 days of life with positive BC that were admitted to the Neonatal Intensive Care Unit (NICU) and Neonatology Department (ND) of the County Emergency Clinical Hospital of Târgu Mureş, a tertiary level hospital, between 2014-2018. The analyzed parameters are: day of life for blood sampling (0-7 days of life), gender, Apgar score (1 and 5 minute), GA, BW, urea, creatinine, total bilirubin, direct bilirubin, aspartate aminotransferase (AST/GOT), alanine aminotransferase (ALT/GPT), c-reactive protein (CPR), bacteria involved, empiric antibiotics administered before blood sampling, temperature of the newborn on the day of BC. We found there is a statistically significant negative correlation between 1 and 5 min Apgar score and creatinine, between GA and urea and also between BW, GA and Direct Bilirubin. We found a statistically significant positive correlation between BW, GA and GPT.
