Urine NT-ProBNP in Neonatal Respiratory Distress

Study Overview
=================
Brief Summary
-----------------
There is a need for a biochemical marker in addition to clinical condition which will help the physician to understand the clinical progress of the disease. Urine Nt-proBNP, which does not need any blood sampling and can be collected easily, has not been evaluated for respiratory distress in newborn. The investigators aim to evaluate the prognostic value of urine NT-proBNP in respiratory diseases in newborns by a controlled trial.

Detailed Description
-----------------
Neonatal diseases such as respiratory distress and transient tachypnea of newborn may require high level of intensive care. On the other hand, some minor difficulties in respiration can resolve within hours. Therefore, there is a need for a biochemical marker in addition to clinical condition which will help the physician to understand the clinical progress of the disease. Serum NT-ProBNP level has been evaluated in transient tachypnea of newborn and found compatible with the clinical progress. Urine NT-proBNP has recently been evaluated in patent ductus arterioses and found compatible with the cardiac progress. However, urine Nt-proBNP, which does not need any blood sampling and can be collected easily, has not been evaluated for respiratory distress in newborn. The investigators aim to evaluate the prognostic value of urine NT-proBNP in respiratory diseases in newborns by a controlled trial.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Respiratory distress group<br>Newborns with respiratory distress will constitute the study group. All patients will be evaluated by Urine NT-proBNP and echocardiography on postnatal days 1-2 and 5-7. | |
| Control Group<br>Newborns without any respiratory and cardiac diseases will constitute the control group, and will be evaluated by urine Nt-proBNP and echocardiography on postnatal days 1-2 and 5-7. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| severity of respiratory distress | Severity of respiratory distress will be evaluated by requirement of supportive treatment such as continuous positive airway pressure, need of intubation, mechanical ventilation and duration of support (hours) | 7 days |
