Co-relation of Hypomagnesemia With Clinical Outcomes in Critically Ill Patients Admitted to a Tertiary Care ICU in Bangladesh

Magnesium is an essential electrolyte involved in numerous physiological processes, including maintaining cellular integrity, regulating muscle tone, supporting cardiovascular function, and modulating immune responses. Despite its critical role, magnesium is often overlooked in clinical practice, earning it the title of the "forgotten electrolyte." Hypomagnesemia, defined as serum magnesium levels below 1.5 mEq/L, has been associated with adverse clinical outcomes such as increased mortality, prolonged ICU stays, and higher requirements for mechanical ventilation. Critically ill patients are particularly vulnerable to hypomagnesemia due to various underlying conditions, gastrointestinal losses, and renal complications. However, limited data are available from Bangladesh on the burden and clinical impact of hypomagnesemia in ICU settings. This study aims to assess the correlation between hypomagnesemia and clinical outcomes, including length of ICU stay, need for mechanical ventilation, and mortality among critically ill patients in a tertiary care ICU in Bangladesh.
