Maintenance of cardiac output in normal range to assure tissues and vital organ perfusion is one of the most important tasks of anesthetists. Hemodynamic and cardiac indices(e.g. cardiac output) change due to either anesthetic drugs or changes in body position during various surgical operations and they have also been important and notable problems. The goal of the present study was to determine the preference of one of volatile or intravenous anesthetic methods in patients in sitting position in terms of adequacy of perfusion to vital organs. We studied combination of two different factors: sitting position and anesthesia regimen in 38 patients undergoing the same type of surgical operation on shoulder(rotator cuff repair). Patients were anesthetized in two different methods after similar induction of anesthesia, and then they were randomly assigned into volatile(Halothane) and intravenous(Propofol) groups. Patients’ cardiac output was measured in several minutes in sitting position during surgery. Finally, it was found out that there was no distinctive difference between mean cardiac output in two groups and no hypothesis was proved for preference of one of these methods of anesthesia to another.
