ABSTRACT
The relationship between the number of platelet and the outcome of trauma is not clearly known. The purpose of this study was to determine the relationship between the number of platelet and the outcome of trauma in traumatic patients [Abdomen and chest] referred to hospital and mortality and morbidity rates after trauma. This deh1ive-analytical study was performed on 300 patients with torso trauma admitted in Al-Zahra hospital in Isfahan Iran in 2005. Injury Severity Score [ISS] complete Blood Count [CBC] and platelet count were measured from all the patients at their arriving to the hospital. We also evaluated the patients for the duration of hospitalization need to stay in ICU duration of ICU care thrombo-embolic events such as deep vein thrombosis [DVT] and respiratory emboli and finally for the outcome of the trauma [death or recovery]. Data were analyzed using student t-test Chi-square and regression. The mean age of patients was 32 +/- 17.51 years from those 78% were men. We found a direct significant relationship between the duration of hospitalization and platelet count and ISS [P0.05]. Our findings suggest that platelet counting in traumatic patients at the beginning of their hospitalization is a good predicting factor to estimate the duration of the hospitalization
