Between groups , comparing with the time point T@ , the amplitude of variation of MAP , COR , and E at T@ in group C were significantly less ( P < @ ) ; the amplitude of variation of HR , MAP , and COR at T@ in group C were less significantly , when compared with the time point T@ ( P < @ ) ; the amplitude of variation of HR , MAP , COR , E , and Glu at T@ and T@ in group C were less significantly , when compared with the time point T@ ( P < @ ) .
