The relationship between magnesium levels and mortality in the respiratory intensive care unit

Magnesium deficiency is defined as a pathophysiologic factor in numerous illnesses. This study aims to define the effects of magnesium levels on patients in the intensive care unit (ICU) regarding length of stay in the ICU, length of mechanical ventilation (MV), and 28-day mortality. The following data were collected during initial assessment of patients admitted to the ICU with acute respiratory failure (ARF). Demographic data, magnesium and potassium levels, Charlson's Comorbidity Index (CCI), Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) scores, length of MV, length of hospital stay in the ICU, 28-day mortality, and ICU discharge status. In the initial serum analysis prior to treatment of patients in the ICU, the mortality rate of the patient group with hypermagnesemia was found to be statistically significant when compared with other magnesium levels (P = .018). Apart from renal failure, ICU mortality is higher in the hypermagnesemia group than other groups. Hypermagnesemia is an electrolyte abnormality that is generally seen in older individuals and those with serious comorbidity and it can be used in mortality prediction.
