Brief summary

The effects of preoperative anemia incidence on postoperative mortality and morbidity in patients undergoing thoracic surgery Preoperative anemia; it is directly related to blood transfusions in the perioperative period, it increases the risk of transfusion-related side effects and complications. The aim of this prospective study was to determine the incidence of preoperative anemia in patients undergoing thoracic surgery and to determine the mortality and morbidity rates that may be related. Preoperative anemia is a risk factor for transfusion of blood and blood products in patients undergoing thoracic surgery. There are three major risk factors for development of preoperative anemia in thoracic surgery: hospital-acquired anemia, iron deficiency anemia, and anemia of chronic disease. Our hypothesis in this study was that anemia may be related to increased perioperative complications, bleeding and transfusion rate.

Interventions

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.
