Lung injury score (LIS) and pulmonary function
lung injury
SECONDARY
LIS was measured by a pulmonary ultrasound, which was examined by a Sonosite portable color ultrasound machine according to the pulmonary BLUE protocol to monitor pulmonary extravascular fluid content and predict the degree of lung injury. Oxygenation was quantified by calculating the PaOAll the parameters of secondary outcomes were measured at the time of beginning infusion (T0) and 1 h (T1), 2 h (T2), and 3 h (T3) after infusion in the operating room.
