Neonatal respiratory distress syndrome (RDS) is the most common cause of respiratory failure in the first few days in life. It is characterized by the tendency of alveoli and terminal bronchioles to collapse due to the lack of surfactant. RDS is inversely related to gestational age and remains a dominant clinical problem encountered among preterm infants.
The reduction in tidal volume secondary to alveolar collapse may result in alveolar derecruitment, cyclic opening and closing of atelectatic alveoli and distal small airways leading to inflammation and lung injury). On the other hand, the use of high positive end expiratory pressure (PEEP) may be associated with excessive lung parenchyma strain and unfavorable hemodynamic effects. Therefore, lung recruitment maneuvers have been proposed and used to open collapsed lung while managing with low pressure PEEP. However, the best recruitment maneuver technique is currently unknown.
Proinflammatory cytokines are synthesized by alveolar macrophages, type II pneumocytes and other local pulmonary cells causing inflammation that starts a cascade leading to lung injury. Nevertheless, they are released systemically and can lead to injury of other organs.
This study aims to measure inflammatory cytokines in the serum of premature infants who receive and do not receive sustained lung inflation. The study hypothesis is that, in premature infants supported with CPAP, the use of sustained inflation is associated with decreased inflammatory biomarkers and improved respiratory outcomes.
The study includes infants with gestational age of 28-24 weeks during the first 6 hours of life who will be randomly assigned to either receive (or do not receive) sustained inflations. Serum concentrations of cytokines (IL-6, IL-8, IL-1β and TNF-α) will be measured at enrollment and at 96 hours. The primary outcome of this study will be the change in serum cytokine concentrations after intervention in both groups. Clinical respiratory outcomes will be monitored.

Experimental: Group A
Infants in the group receive CPAP for respiratory support in the delivery room. In addition, they receive a total of 15 sustained lung inflations in the first 96 hours of life; 6 in the first day, 3 in the second day, 3 in the third day and 3 in the forth day of life.
Procedure: Sustained lung inflation
Preterm infants will receive a total of 15 sustained lung inflations during the first 4 days of life as follows:
Experimental: Group B
Infants in the group receive CPAP for respiratory support in the delivery room. No sustained lung inflation will be applied.
Procedure: Continuous positive airway pressure (CPAP)
Preterm infants will receive CPAP for respiratory support.
Other Name: CPAP
Active Comparator: Group C
Infants in this group are intubated in the delivery room and supported with mechanical ventilation.
Procedure: Mechanical ventilation
Preterm infants in this group will receive mechanical ventilation for respiratory support
