Data are presented as the median (interquartile range). aMann-Whitney rank sum test: p < 0.05 versus PCV. b-dFriedman repeated measures analysis of variance on ranks with all pairwise multiple comparison procedures (Student-Newman-Keuls method): bversus Tbaseline, cversus TALI, dversus T6 h (p < 0.05). PCV, pressure-controlled ventilation; PCV+R, pressure-controlled ventilation with recruitment manoeuvre; T6 h, time point 6 hours after randomisation; T18 h, time point 18 hours after randomisation; T24 h, time point 24 hours after randomisation; TALI, time point after lung injury; Tbaseline, baseline time point. | ||||||
