Impact of serum magnesium levels on critically ill COPD patients: A retrospective study

The relationship between serum magnesium levels and clinical outcomes, including mortality and the need for invasive or non-invasive mechanical ventilation, has yet to be thoroughly investigated specifically in COPD patients admitted to the ICU. This study aims to investigate the impact of serum magnesium levels on mortality and other clinical outcomes—such as mechanical ventilation requirements, ventilation duration, and ICU length of stay—in critically ill patients with COPD, contributing valuable insights into the management of this patient population. Relevant data, including patients’ gender, age, existing co-morbidities, serum magnesium levels on admission, mechanical ventilation status, mortality, and length of stay, will be collected from medical records, with no active participation required from the patients. The observation period will begin on the day of ICU admission and continue until the patient is discharged.
