Study of Serum Magnesium Levels in Patients Admitted with Sepsis in Intensive Care Unit
Patil PSG, Aslam SS
Abstract: Background
Magnesium plays an important role in sepsis, and this could be attributed to its
effects on the immune system, which are important in the pathogenesis of sepsis.
Magnesium deficiency, one of the underrated electrolyte abnormalities, is observed
in critically ill patients admitted to intensive care unit (ICU).
Objective
To find the association of serum magnesium with the outcome, duration, and need
for ventilation.
Method
The hospital-based prospective observational study included patients > 18 years
(N=150) with sepsis admitted to intensive care unit. Patients were divided into
normomagnesemia (n=75) and hypomagnesemia (n=75) groups. Sequential Organ
Failure Assessment Score (SOFA) score, length of intensive care unit stay, need and
duration of mechanical ventilatory requirement, and outcomes were compared
between the two groups.
Result
The mean Sequential Organ Failure Assessment score (5.87 ± 2.31 vs. 3.85 ± 1.75),
mean duration of intensive care unit stay (in days) (7.21 ± 1.74 vs. 5.24 ± 1.38), the
mean duration of mechanical ventilatory requirement (in days) (4.05 ± 3.47 vs. 1.13
± 1.98), and mortality rate were (33% vs. 4%) were higher in the hypomagnesemia
group when compared to the normomagnesemia group (p < 0.001 for all).
Conclusion
The study concludes that hypomagnesaemia is a significant electrolyte abnormality in
critically ill sepsis patients. Hypomagnesaemia, Sequential Organ Failure Assessment
Score, and mechanical ventilation are the factors that independently predicted
mortality in intensive care unit patients. Hence, clinicians should regularly monitor
the occurrence of hypomagnesemia in intensive care unit patients to reduce its poor
clinical outcomes.
