after treatment with indomethacin there were significant decreases in pulmonary artery pressure ( mean +/- sem ; 48 +/- 1 to 22 +/- 3 mm hg , p less than 0.001 ) , pulmonary artery wedge pressure ( 7.5 +/- 1.3 to 2.2 +/- 0.4 mm hg , p less than 0.001 ) and thromboxane b2 ( 6.51 +/- 1.56 to 1.01 +/- 0.27 ng/ml , p less than 0.01 ) and an increase in dynamic lung compliance ( 1.10 +/- 0.10 to 1.28 +/- 0.14 ml/cm h2o/kg , p less than 0.01 ) over the study period .
