| description | <p>Abstract</p> <p>Background</p> <p>Despite continuous improvements in materials and perfusion techniques, cardiac surgery still causes lung injury and a delay of pulmonary recovery. Currently, there is no gold standard for quantifying cardiac surgery induced lung injury and dysfunction. Adding objective measures, such as plasma biomarkers, could be of great use here. In this study the utility of lung epithelium specific proteins as biomarkers for lung dysfunction was evaluated.</p> <p>Methods</p> <p>Serial measurements of plasma concentrations of Clara cell 16 kD (CC16) protein, Surfactant protein D (SP-D), Elastase and Myeloperoxidase were performed on blood samples from 40 patients who underwent coronary artery bypass grafting with cardiopulmonary bypass (CABG, n = 20) or without cardiopulmonary bypass (OPCAB, n = 20).</p> <p>Results</p> <p>The increase of SP-D and CC16 between pre-operative concentrations and concentrations at the end of cardiopulmonary bypass, correlated with the Aa-O<sub>2</sub> gradient at 1 hour on the ICU (R<sub>s</sub> = 0.409, <it>p</it> = .016 and R<sub>s</sub> = 0.343, <it>p</it> = .043, respectively).</p> <p>Furthermore, SP-D and CC16 were higher in CABG than in OPCAB at the end of surgery [8.96 vs. 4.91 ng/mL, <it>p</it> = .042 and 92 vs. 113%, <it>p</it> = .007, respectively].
