Abstract
Due to the changes in major trauma epidemiology, the management of thoracoabdominal trauma evolved in time. The thoracoabdominal major lesions were treated in the past by emergency laparotomy or tocachotomy. The morbidity associated with nontherapeutic laparotomies or thoracotomies lead to an increase of using conservative ways of treatment. We accomplished a retrospective study in which we included 234 patients, all of them diagnosed with thoracoabdominal trauma who were hospitalized in the General Surgery Ward. The objective of this study is to determine whether there is a correlation between the value of hematocrit and hemoglobin at patient admission and the values at discharge, in patients who required blood transfusion during hospitalization.
