Infants included were randomly assigned into two groups, Group A who were subjected to LRM using HFOV (20 cases) and Group B who were subjected to LRM using VTV\/AC (20 cases). TGF-\u03b21 level was measured in BAL samples of all studied infants at two time points; before lung recruitment maneuver and at day 5 after lung recruitment or just before extubation if extubation occurs earlier than 5 days.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Lung recruitment maneuver had no significant effect on time to extubation.
