Introduction

The importance of magnesium as an essential nutrient in health and disease has been recognized for many years [1]. Our previous studies showed the presence of a high incidence of hypomagnesemia in critically ill patients [2]. The aim of the present study is to assess the incidence of hypomagnesemia in the patients admitted to the Emergency Department.

Methods

One hundred patients admitted to the Emergency Department of Clinica São Vicente were studied. All patients had serum electrolyte concentrations measured at admission. Correlation between electrolyte levels was obtained by linear regression.

Results

The finding of hypomagnesemia was found to correlate significantly with hypocalcemia (r = 0.2098, P = 0.038), with hypophosphatemia (r = 0.3244, P = 0.001), and with hypokalemia (r = 0.253, P = 0.012)

Conclusions

Low magnesium concentrations are common in patients admitted to the Emergency Department. The presence of hypomagnesemia is associated with hypocalcemia, with hypophosphatemia, and with hypokalemia.
