| Background: Preoperative anemia is associated with increased morbidity and mortality after cardiac surgery, so we investigated the effect of preoperative hemoglobin levels on early outcome of valve replacement surgeries. Aim of work: Studying the effect of preoperative hemoglobin levels on early outcome of valve replacement surgeries. Patients & Methods: This retrospective cross-sectional study included (782 cases) all patients underwent open heart surgery for valve replacement surgeries, except those with the exclusion criteria (patients with preoperative heart failure, renal impairment, chronic liver disease or chronic obstructive pulmonary diseases), during a duration of 4 years from 1st of June 2013 till 31th of May 2017 in the department of cardiothoracic surgery at Zagazig University Hospitals. Anemia was defined as hemoglobin >12.0 g/dL in women and >13.0 g/dL in men as reported by the World Health Organization (WHO). The items we focused on during our study were ICU stay duration, post-operative bleeding, sternal wound infection, myocardial infarction, hospital stay duration and in-hospital mortality. Results: In patients undergoing open heart surgery, 22% of males had preoperative anemia while 26% of females had preoperative anemia. The group with preoperative anemia was associated with increased incidence of adverse events more than the group with normal preoperative hemoglobin levels. The concluded results showed that: patients who suffered from prolonged ICU stay (59.8% vs. 29.8%), post-operative bleeding (88.0% vs. 54.9%), sternal wound infection (6.0% vs. 2.8%), myocardial infarction (3.9% vs. 2%), prolonged hospital stay (61.5% vs. 31.8%) and inhospital mortality (7.7% vs. 4%) among the anemic and normal group respectively. Conclusions: Our results indicate that preoperative anemia is associated with a significantly increased risk of post-operative morbidity and mortality. | ||||
