The aim of the study is to investigate MPV (mean platelet volume) showing platelet reactivity if it is associated with the severity of the critical illness or mortality in ICU patients. Study group (130 patients) was formed from survivor group (68 patients) and non-survivor group (62 patients). Platelet counts and MPV values were compared between two groups in the first five days of hospitalization. MPV correlation was studied with APACHE II score, age, haemoglobin level, duration in the ICU and as an independent risk factor in mortality. Mean age and APACHE scores were significantly higher in non-survivor group compared to survivor group (p<0.05). There was no significant difference between two groups according to MPV and platelet counts in first five days of hospitalization. There was a unique positive correlation between MPV and APACHE score (r: 0.34, p< 0.05). Only age was independent risk factor in mortality. In our study, we found positive correlation between severity of critical illness and MPV. However, there was no relation between MPV and mortality in heterogenic critical patients. Subgroup analysis of patients in ICU might be useful in assessing prediction for mortality.
