Intensive care units are medical units where patients are closely monitored 24 hours a day due to critical health problems that threaten their lives and where rapid interventions are made when necessary. The clinical conditions of patients in these units can change rapidly. There are many studies in the literature indicating that inflammation indicators such as Neutrophil/Lymphocyte, Platelet/Lymphocyte and C-Reactive Protein/Albumin ratios and blood gas values such as Lactate and Base Deficit are simple, cheap and rapid biomarkers that can provide an early idea about the clinical course of patients.

The researchers aimed to evaluate the relationship between Neutrophil/Lymphocyte, Platelet/Lymphocyte and C-Reactive Protein/Albumin ratios and biomarkers such as Lactate and Base Deficit with the clinical course and survival of trauma patients admitted to the ICU and to see the compatibility of our data with the existing literature.
