[The disturbance of the magnesium management in patients in grave clinical status].

The analysis included 46 patients (27 men and 19 women), aged 41 to 76 years, who required intensive medical care because of a grave clinical state. In all af them, as in a group of patients treated because of illnesses identical to those of the basic group but not requiring intensive medical care (CG), as well as in a reference group (RG)--blood donors, the determinations were conducted of the magnesium concentration in the serum with the flame atomic absorptive spectrometry method. It was confirmed that in the patients in grave clinical state the average concentration in the serum of that element was statistically significantly lower that in the other groups (CG and RG). The average magnesium concentration also differs statistically really between the CG and RG. A critical value was also determined of the magnesium concentration in the serum raising 5.78 micrograms/ml, which may be the prognosis of the metabolic disturbances leading to a grave clinical state.
