Objectives

Narrative objectives1

The risk of perioperative complications tends to increase with the aging of society and the development of surgical techniques and anesthesia methods. However, available medical resources are limited, and it is difficult to allocate the same amount of medical resources to all patients. If perioperative patient risk can be easily assessed, patient outcomes can be improved by focusing medical resources on high risk patients. Currently, risk assessment for each disease and organ is widely performed, but perioperative prognosis is generally judged comprehensively by attending physicians and anesthesiologists based on individual risk assessments, which is not easy to perform and is not accurate. Red cell distribution width (RDW) is an inexpensive measure of red cell size variability that has been associated with hematologic disorders, iron deficiency anemia, and bone marrow dysfunction. Values above the normal range reflect the presence of small and large erythrocytes. Recently, RDW has been reported to be a useful prognostic marker for patients with chronic diseases and is considered a strong independent risk factor for mortality. More recently, RDW has also been reported to be useful as a short and long term prognostic marker for acute illnesses such as sepsis. In the perioperative period, RDW has been studied in adult noncardiac surgical patients, but its usefulness in predicting life expectancy and perioperative complications in a variety of conditions, including cardiac surgery patients, surgical patients with coexisting sepsis, emergency patients, and pediatric surgical patients is not known. To develop a simple short and long term prognostic marker for surgical patients. This study will establish a simple method to predict prognosis in surgical patients.
