Effects of fluid resuscitation on MAP in the three groups. MAP in all patients was registered by professional statisticians in the hospitals. There were no differences in MAP among the three groups at all the six time points. Comparing MAP in the same group, MAP at T₆₀, T₉₀, T₁₂₀ and T_8h was significantly higher than that at T₀ in the Ns group; the parameter at T₉₀, T₁₂₀ and T_8h was higher than at T₀ in the Hs group; and MAP at T₃₀, T₆₀, T₉₀, T₁₂₀ and T_8h were higher than that at T₀ in the Sb group (*p < 0.05). MAP increased earlier in the Sb group than in the Ns and Hs groups.
