Predictive Role of Glucose/Potassium Ratio on Mortality in Major Burns.

Major burns, especially electrical burns, facial burns, inhalation burns, burns with large burn surface areas, and deep burns, have a high mortality risk. Early detection of this risk may be critical to reducing mortality rates. For this reason, trauma centers are working on rapid and effective prognostic markers. In trauma and stress situations, glucose levels rise while potassium levels fall due to increased catecholamines. The literature reports that hyperglycemia, also known as the glucose-potassium ratio, can rapidly and effectively predict morbidity and mortality in patients suffering from subarachnoid hemorrhage, pulmonary embolism, traumatic brain injury, or blunt abdominal trauma. Many publications show that increased glucose is associated with mortality and morbidity in critical illnesses and trauma. The isolated glucose-potassium ratio has a higher predictive ability for mortality and morbidity compared to glucose and potassium levels. In this study, investigators aimed to examine the prognostic value of the glucose-to-potassium ratio in participants with major burn trauma.
