Risk Factors for Sepsis in Postoperative Patients
Main Article Content
Abstract
Sepsis is a severe acute infection that can lead to organ failure and mortality in 30-50% of patients. It ranks among the top 10 causes of mortality in the United States and has increased significantly since the 1970s. Postoperative sepsis, the primary type of sepsis, accounts for almost one-third of all sepsis cases.
Postoperative sepsis is a major cause of illness and death for hospitalized patients, often leading to multiple organ failure and mortality. A study found that patients aged 18 years or older who have undergone surgical interventions and have been hospitalized for at least 4 days after the operation have a higher likelihood of developing sepsis. The most prevalent complication after radical gastrectomy for stomach cancer is postoperative infection, which occurs through leukocyte depletion in transfusion patient.
Being male or over 65 significantly increased the likelihood of having postoperative sepsis. Sex hormones significantly influence the body's response to sepsis, and elderly individuals may be more susceptible due to deterioration of immune system function and age-related immunosenescence. Chronic renal illness, diabetes, and chronic heart failure have the highest risks of developing postoperative sepsis, ranked first, second, and third, respectively.
Dysfunctions in the cardiovascular and hematological systems also have the highest probability of leading to the development of postoperative sepsis. These findings suggest potential areas for future research to decrease the impact of the disease.
