“…23 Lastly, greater blood loss denotes decreasing hemoglobin counts and consequently, relative hypoxemia, known to be unfavorable in any major surgical procedure. 24 As could be expected, patients who developed complications had a longer hospital stay likely because more time was required to address the post-operative problems.…”

Objectives: Axial flap surgery is associated with numerous complications. The purpose of this study is to determine the frequency of these complications, and identify possible factors contributory to their occurrence. Methods: Study design: Cross-sectional study Setting: Tertiary public university hospital Subjects: Records of all patients who underwent axial pedicled flap reconstruction at the otorhinolaryngology ward of our tertiary public university hospital from January 2013 to July 2015 were retrospectively reviewed, and data consisting of age, sex, diagnosis, disease stage, smoking history, alcohol intake, co-morbidities, past operations, pre-operative hemoglobin and albumin, total operative time, total blood loss, location and total area of the surgical defect, and length of hospitalization were tabulated. All complications were listed. Data were analyzed for any potential trends. Results: A total of 38 patients underwent axial pedicled flap reconstruction in the study period. Nineteen out of 38 (50%) cases involved complications. The most common complication was infection. Most of the complications occurred in males with history of alcohol intake, advanced cancer stage, significant blood loss, recurrent tumors, low pre-operative hemoglobin and albumin levels, and a large area of surgical defect. Conclusions: The complication rate for axial flap surgery in our series was significant at 50%. Potential risk factors identified were male gender, advanced cancer stage, tumor recurrence, alcohol intake, low pre-operative hemoglobin and albumin levels, significant blood loss, longer operative time, and a larger surgical defect.

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 1 st of June 2013 till 31 th 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.
