Role of Lung Ultrasound In Assessment Of Recruitment Maneuvers In Ventilated Preterms with Respiratory Distress Syndrome and Its Correlation with tracheal IL-6 Level

Abstract

ur study is a randomized controlled study. We hypothesized that it would be beneficial to use lung ultrasonography in detecting opening and closing lung pressures in ventilated preterm neonates with respiratory distress syndrome as it allows a regional analysis of lung recruitment in dependent and nondependent lung regions (Bouhemad et al., 2011). Our study also determined optimization of lung volume and its correlation with pulmonary inflammatory reaction as evidenced by IL-6 level in tracheal aspirate. The studied population included 44 preterm infants. Anthropometric measurements, gestational age, sex, mode of delivery, maternal disease and Apgar score were matched in the two studied groups indicating successful randomization as seen in these balanced demographic variables between the groups. The studied population included 44 preterm infants. Then they were allocated randomly to one of 2 groups in order by admission:  Group A: 22 patients underwent LUS guided RM.  Group B: 22 patients underwent non-LUS guided RM. This is considered the control group. Our study showed improvement in both CXR and LUS grades after applying recruitment maneuver. This proves the
