Correlation Between Nutritional Status And Pulmonary Infection In Maintenance Hemodialysis Patients

Objective: To provide basis for early intervention and treatment of pulmonary infection in maintenance hemodialysis patients by analyzing the nutritional status of maintenance hemodialysis patients and its correlation with pulmonary infection.Methods: 149 patients with end-stage renal disease and maintenance hemodialysis admitted in the Department of Nephrology of Ningguo people’s Hospital from January2018 to January 2021 were included in the study.According to whether the patients were complicated with pulmonary infection during treatment,they were divided into 68 cases in the pulmonary infection group(group A)and 81 cases in the non pulmonary infection group(group B).The nutritional status of all patients was scored according to the patient self-assessment subjective comprehensive assessment scale.At the same time,the differences in nutritional status and the levels of hemoglobin(HB),serum albumin(ALB),prealbumin(PA),cholesterol(CH)and creatinine(CR)between the two groups were compared,and the correlation between malnutrition and pulmonary infection was analyzed.Results: there was no significant difference in gender,age,course of disease and average dialysis time between the two groups(P > 0.05).The incidence of malnutrition in patients with pulmonary infection was 86.8%,which was significantly higher than59.3% in patients without pulmonary infection(P < 0.05).The levels of hemoglobin(HB),serum albumin(ALB)and prealbumin(PA)in the pulmonary infection group were lower than those in the uninfected group,and the level of serum creatinine(CR)was higher than those in the uninfected group(P < 0.05).Staphylococcus aureus and Streptococcus pneumoniae were the most common pathogens causing pulmonary infection in maintenance hemodialysis patients,accounting for 26.8% and 21.4%respectively.The correlation coefficient between malnutrition and pulmonary infection was 0.489(P = 0.000).Conclusion: 1.The nutritional status of patients with pulmonary infection during maintenance hemodialysis is significantly lower than that of patients without pulmonary infection.2.Pulmonary infection has a negative impact on the dialysis quality of patients;3.There was a positive correlation between malnutrition and the incidence of pulmonary infection.
