Kinetic changes of lactate and its clearance rate.

	Lactate in the Shenfu group (N = 102)	Lactate in the control group (N = 97)	Lactate clearance in the Shenfu group (N = 85)	Lactate clearance in the control group (N = 74)
0 h	3.83 ± 2.32	3.99 ± 2.87
6 h	3.45 ± 2.19	3.59 ± 2.84	−0.07 ± 0.44	−0.10 ± 0.32
12 h	3.29 ± 2.24	3.30 ± 2.76	−0.13 ± 0.36	−0.15 ± 0.41
24 h	2.93 ± 2.40	2.83 ± 2.52	−0.22 ± 0.55	−0.28 ± 0.35
48 h	2.51 ± 2.28	2.67 ± 2.53	−0.34 ± 0.52	−0.33 ± 0.36
144 h	2.37 ± 2.81	2.60 ± 2.52	−0.40 ± 0.59	−0.33 ± 0.39

Lactate clearance was calculated and compared only in patients with elevated lactate. There was no difference at each time point between the two groups.
