Comparison between clinical judgment and integrated lung and inferior vena cava ultrasonography for dry weight estimation in hemodialysis patients

Introduction: Correct dry weight estimation is very crucial for hemodialysis (HD) patients to maintain euvolemia. Most dialysis centers practice clinical judgment for dry weight estimation, which is subjective and can differ significantly from the actual weight. We designed this study to redefine the clinically estimated dry weight of patients on HD using integrated lung–inferior vena cava (IVC) ultrasonography (USG) and compare the symptoms arising due to volume overload and/or volume depletion before and after modifying the dry weight. Methods: Breathlessness and orthostatic giddiness were scored and documented for 2 weeks while patients were on HD based on clinically estimated dry weight and again for 2 weeks after redefining dry weight using lung–IVC USG. New dry weight was defined as the weight of the patient at which the number of B‐lines was
