Thyroid function seven days after birth of preterm infants and its influencing factors analysis
Objective To investigate the incidence of abnormal thyroid function seven days after birth of preterm infants,and to analyze the influencing factors.Methods Clinical data of 261 preterm infants born and admitted to the Department of Neonatology,Shanxi Children's Hospital,Shanxi Medical University from March to August 2023 were retrospectively analyzed.According to the results of thyroid function seven days after birth,they were divided into normal group and abnormal group.The influencing factors of abnormal thyroid function seven days after birth of preterm infants were analyzed.Results Among 261 preterm infants,53(20.3%)had abnormal thyroid function.There were statistically significant differences in gestational age,birth weight,delivery mode,gestational hypertension,use of pulmonary surfactant,use of fat emulsion,and combined patent ductus arteriosus(PDA)between two groups(P<0.05).Gestational age(OR=0.187),delivery mode(OR=O.197),and combined patent ductus arteriosus(OR=0.251)were the influencing factors of abnormal thyroid function seven days after birth of preterm infants(P<0.05).Conclusion Thyroid function should be closely monitored clinically in preterm infants with high-risk factors so as to achieve early detection,diagnosis,and treatment,and to improve prognosis.
