Clinical application of lung ultrasound in volume assessment of hemodialysis patients
Objective To explore the application value of lung ultrasound B-line in the assessment of volume status in hemodialysis patients.Methods A total of 93 maintenance hemodialysis patients in the dialy-sis center of our hospital from January 2022 to June 2023 were selected.Ultrasound was used to measure the number of B-lines and inferior vena cava diameter(IVCD)before and after dialysis.The changes of the two before and after dialysis were compared,and the correlation between the number of B-lines and IVCD before and after dialysis was analyzed.At the same time,62 patients with hypertension were selected,and the tradi-tional clinical evaluation method and lung ultrasound B-line evaluation method were used to adjust the dry weight of dialysis.The number of B-lines,the degree of dry weight loss,blood pressure and the incidence of di-alysis hypotension were compared between the two groups.Results The number of B-lines,IVCD and body weight after dialysis were lower than those before dialysis,and the differences were statistically significant(P<0.05).The number of B-lines before dialysis was positively correlated with IVCD(r=0.536,P<0.05).Compared with the traditional evaluation group,the degree of blood pressure decline and dry weight loss in the lung ultrasound B-line group were greater,and the incidence of dialysis hypotension was lower,the differences were statistically significant(P<0.05).Conclusion In hemodialysis patients,the application of lung ultra-sound B-line detection for volume assessment has good clinical value.
