Abstract：Objective: To study the relationship between serum hemoglobin (HB), serum albumin (ALB), body mass index (BMI) and pulmonary infection in maintenance hemodialysis patients and the risk factors of pulmonary infection. Methods: A total of 81 patients with maintenance hemodialysis in our hospital from January 2016 to January 2020 were selected as the research objects. According to whether pulmonary infection occurred in patients during hemodialysis treatment, all patients were divided into infection group (23 cases) and non-infection group (58 cases). Gender, age, BMI, length of first dialysis stay, vascular access, hypertension, diabetes, smoking history, Hb and ALB expression levels were compared between the two groups. ROC curve was used to analyze the value of serum Hb, ALB and BMI in predicting pulmonary infection in maintenance hemodialysis patients; Non- conditional logistic stepwise regression was used to analyze the influencing factors of pulmonary infection in maintenance hemodialysis patients. Results: By univariate analysis, compared with the non-infection group, the proportion of patients with age ≥ 60 years, diabetes mellitus and smoking history in the infection group was higher, and the BMI, Hb and ALB levels in the infection group were higher, and the differences were statistically significant (P<0.05); ROC analysis showed that the area under the curve of BMI, Hb and ALB in predicting pulmonary infection in maintenance hemodialysis patients was 0.804, 0.804 and 0.850, respectively, and the differences were statistically significant (P<0.05); Logistic regression analysis confirmed that age ≥ 60 years old, BMI ≥ 24.205kg/m2, diabetes mellitus, smoking history, Hb ≤ 82.875g/l, ALB ≤ 33.445g/l were the risk factors of pulmonary infection in maintenance hemodialysis patients, the differences were statistically significant (P<0.05). Conclusion: Age, diabetes and smoking history are independent risk factors for pulmonary infection in maintenance hemodialysis patients. BMI, Hb and ALB have certain predictive value for pulmonary infection in maintenance hemodialysis patients
