Approach to Hypomagnesemia in the ICU
摘要
Magnesium is an essential mineral that plays a pivotal role in numerous physiological processes. Serving as a cofactor in over 300 enzymatic reactions—including ATP synthesis and DNA replication—it is fundamental to energy production, muscle and nerve function, and the immune response. Magnesium’s influence extends from cellular metabolism to the maintenance of normal heart rhythm and bone health. Hypomagnesemia, defined as low serum magnesium levels, is a common electrolyte disturbance not only in the intensive care unit (ICU) but also among patients with chronic illnesses such as diabetes, cardiovascular diseases, and gastrointestinal disorders.
