Lung ultrasound and assessment of fluid overload in peritoneal dialysis

Key Points

Lung ultrasound effectively identifies fluid overload in peritoneal dialysis patients, improving volume status assessment.
Correlations found between B-line scores and overhydration indicated by bioimpedance analysis, with r = 0.625.
This cross-sectional study included 22 patients and utilized a comprehensive 8-zone ultrasound scanning protocol.
Findings highlight the noninvasive nature of lung ultrasound for fluid overload detection, suggesting significant clinical implications.

Abstract

Fluid management remains a major challenge in peritoneal dialysis (PD), particularly due to the difficulty in detecting subclinical hypervolemia. This cross-sectional, single-center study, with a sample of 22 patients, investigated the utility of lung ultrasound (LUS) as a complementary tool for volume status assessment. Using an 8-zone scanning protocol and B-line scoring system, LUS was performed during routine visits alongside inferior vena cava (IVC) evaluation and bioimpedance analysis (BIA). The results showed strong correlations between B-line scores and both overhydration, as measured by BIA (r = 0.625), and IVC collapsibility index (r = –0.722). Notably, half of the patients considered clinically euvolemic exhibited signs of hypervolemia based on ultrasonographic criteria. These findings suggest that LUS is a noninvasive, practical, and effective method for identifying fluid overload not evident through standard clinical evaluation, supporting its integration into routine care for PD patients.
