ObjectiveTo investigate the relationship between the coma scores-Glasgow coma scale (GCS), Sequential Organ Failure Assessment (SOFA), and Acute Physiological and Chronic Health Assessment (APACHE-II)-in intensive care unit (ICU) patients and the percentage of macrocytosis (%MAC), immature granulocyte (IG), cellular haemoglobin concentration (cHGB), nucleated red blood cell (NRBC), nucleated red cell/ white cell ratio (NR/W), hyperchromic ratio (%HPR), and platelet distribution width (PDW) values.Study DesignA descriptive comparative study. Place and Duration of the Study: Medicine Faculty, University of Harran, Turkiye, from December 2020 to May 2022.MethodologyThe hemogram parameters of the patient groups with a GCS of 3-8 (n=51) and a GCS of 9-15 (n=43) and a control group of 55 healthy volunteers were measured using the new-generation hemogram autoanalyzer AlinityHQ (Abbott, USA). These parameters were compared with the coma scores (GCS, SOFA, and APACHE-II) of the patients.ResultsThere was a statistically significant difference in IG, %MAC and PDW values (p-values were 0.025, 0.011, and 0.004, respectively) and an inverse correlation with GCS scores (correlation coefficients were -0.247, -0.264, and -0.297, respectively) was observed. There was also a significant correlation between the SOFA scores and %HPR and cHGB (correlation coefficients were 0.234, -0.358, p-values were 0.025, 0.001, respectively), and the APACHE-II scores and NRBC and NR/W values (correlation coefficients were -0.270, -0.247, p values were 0.009, 0.017, respectively).ConclusionWhile other haematological parameters other than PDW were not associated with coma scores, parameters measured using new-generation haematological devices (%MAC, IG, cHGB, NRBC, NR/W, and %HPR) were found to be associated with estimated coma scores. These parameters can therefore be used as simple, rapid prognostic biomarkers and assist researchers in the development of new scoring models.Key WordsICU, Hyper, Coma, Sofa, Apache.
