Bronchopulmonary Dysplasia Clinical Trials

In adults and children low or high blood chloride levels are linked to the risk of death. The aim of this observational study is to determine whether there is a relationship between low or high blood chloride levels and the risk of death or long-term lung problems. We will also learn the risk factors and associated conditions of high or low blood chloride levels. We will include infants born before 32 weeks of pregnancy or have a birth weight of less than 1500 grams in the study. The main question it aims to answer is: Is there a relationship between low or high blood chloride levels in the first 4-6 weeks of life and risk of death or long-term lung problems in premature babies? We will examine the medical reports of babies who were followed up in neonatal intensive care unit over the past 5 years.
