Background: Although Transient tachypnea of the newborn (TTN) is one of the most common causes of respiratory distress in the newborn period, there is no laboratory parameter used to diagnose it. Immatur granulocyte (IG) measurement is accepted as a useful indicator that can be used in early detection of many infectious conditions, especially neonatal sepsis. In this study, it was aimed to determine if IG and other complete blood count (CBC) parameters could be used as laboratory findings supporting TTN diagnosis.
Materials and methods: This study, which was retrospectively planned, was conducted in the neonatal intensive care unit (NICU) a public hospital between January 1, 2019 and January 31, 2021. Randomly selected 50 infants, hospitalized with the diagnosis of TTN, constituted the patient group of the study. 50 infants hospitalized with the diagnosis of hyperbilirubinemia and did not have any additional problems accepted as the control group. IG and other CBC parameters of infants in the patient and control groups were compared in the study.
Results: There was no significant difference between the patient and control groups in terms of demographic data and types of delivery (p > 0.05). The rate of delivery by elective cesarean section (C/S) was significantly higher than the rate of normal spontaneous vaginal (NSV) delivery in the patient group (p < 0.001). The IG number and percentage, WBC (white blood cell) count, RDW (red cell distribution width), number and percentage of NRBC (nucleated red blood cell), neutrophil and lymphocyte ratio, count and percentage of basophil and PLR (platelet/lymphocyte ratio) of the patient group was significantly higher than the control group (p < 0.05).
Conclusion: According to the findings obtained in the study, it was concluded that IG and other CBC parameters may be used to support clinical and imaging findings to diagnose transient tachypnea of the newborn.
