Description of intervention(s) / exposure
We enrolled consecutive 104 patients between the age of 18 and 79 years. Patients’ demographic data, preoperative and postoperative complete blood count, rate of blood and blood product transfusions and complications were recorded during surgery. Additionally, other laboratory tests, surgery type, re-exploration, length of stay at hospital and intensive care unit were determined and recorded at first 48 hours after surgery. We classified patients into two groups: patients with anemia (n=29) and patients without anemia (n=75). According to the World Health Organization, anemia is defined as a hemoglobin level less than 12 g/dL in women and less than 13.0 g/dL in men.We took these reference levels into consideration for diagnosis of preoperative anemia in our study.
