Panel A: Data are non parametric and presented as mean and standard error of the mean. * Indicates P < 0.05 for post operative crystalloid and colloid vs. baseline (P=0.013, 0.016 respectively). Panel B: Data are non parametric and presented as mean and standard error of the mean. * Indicates P < 0.05 for post operative crystalloid and colloid vs. baseline (P=0.025, 0.012 respectively). Panel C: Data are non parametric and presented as mean and standard error of the mean. * Indicates P < 0.05 for post operative crystalloid and colloid vs. baseline (P=0.001, 0.004 respectively).
