- Normal distributed data are given as mean ± SD. The EL, E and L groups demonstrated differences in blood gas values. The pH, PaO2, HCO3
− and BE values in the EL group were higher than that in the E group (PH: EL vs. E, P = 0.021; PaO2: EL vs. E, P < 0.001; HCO3
−: EL vs. E, P = 0.004; BE: EL vs. E, P = 0.004). The PH and BE values in the EL group were higher than that in the L group (PH: EL vs. L, P = 0.024; BE: EL vs. L, P = 0.01). The blood lactate value in the EL group were lower than that of the E or L group (EL vs. E, P = 0.018; EL vs. L, P = 0.001). There were no differences between EL group and L group in the PaO2 and HCO3
− values (P > 0.05). *
