The role of inferior vena cava diameter and collapsibility index assessment of fluid status among hemodialysis dependent patients : A cross sectional comparative study

Introduction: Accurate assessment of fluid status in hemodialysis dependent patients to achieve a euvolumic state remains the cornerstone of Chronic Kidney disease management. There are various clinical and physical examination parameters for optimal estimation of fluid status in CKD patients. This research focuses on studying the comparison between inferior vena cava diameter and compressibility index with physical signs for fluid manage in pre and post dialysis patients. Methods and results: A cross sectional comparative study was conducted out at the department of medicine and dialysis unit of Combined Military Hospital (CMH) Malir. A total of 45 participants were inducted in the study. The sample was predominantly male i.e. 62.20% (n=28) with 37.80% (n=17) being female. The mean age of the patients was 50.47 years (SD = 11.8). Comorbidities were prevalent, with hypertension present in 93.30% of patients, followed by diabetes (40.00%) and ischemic heart diseases (17.80%). Conclusion: Based on the research findings we concluded that ultrasound is a significantly reliable method for estimation of the fluid status in pre and post HD patients as compared to physical signs.
