Measurement of Fluid Status Using Bioimpedance Methods in Korean Pediatric Patients on Hemodialysis

Abstract

Adequate fluid management is an important therapeutic goal of dialysis. Recently, bioelectrical impedance methods have been used to determine body fluid status, but pediatric reports are rare. To determine the accuracy of bioelectrical impedance methods in the assessment of body fluid statusof children undergoing hemodialysis (HD), 12 children on HD were studied. A multi-frequency bioimpedance analysis device (Inbody S10) and bioimpedance spectroscopy device (BCM) were used to evaluate fluid status. Fluid removal during a HD session (assessed as body-weight change, ΔBWt) was compared with the difference in total body water determined by each device (measured fluid difference, ΔMF), which showed strong correlation using either method (Pearson's coefficient, r = 0.772 with Inbody S10 vs. 0.799 with BCM). Bioimpedance measurement indicated fluid overload (FO; ΔHS greater than 7%) in 34.8% with Inbody S10 and 56.5% with BCM, and only about 60% of children with FO by bioimpedance methods showed clinical symptoms such as hypertension and edema. In some patients with larger weight gain Inbody S10-assessed overhydration (OH) was much smaller than BCM-assessed OH, suggesting that BCM is more relevant in estimating fluid accumulation amount than Inbody S10. To our knowledge, this is the first report on the use of body composition monitors to assess fluid status in Korean children receiving HD.

Evaluating of altered hydration status on effectiveness of body composition analysis using bioelectric impedance analysis

“…It has been revealed that BIA is a useful, easily applicable, and inexpensive tool for the evaluation of body composition of obese [10], cardiometabolic disorders [1][2][3][4], cancer [8], and hemodialysis patients [18]. Obtaining confidential information with regarding specific proportion of each section of body composition (TBW, FFM, %FM and FM) in health and also some disorder is a continue interest of clinical and scientist.…”

“…Importantly, any impairment of nutritional conditions may have a remarkable effect on the content of body composition and trigger many serious clinical conditions [1,2]. The assessment of body composition has long been used to obtain important information with regard to health status of the individual [3,4]. Thus, the effective measurement of body composition becomes extremely important in clinical medicine.…”

“…To conduct the body composition analyses, an 8-electrode multifrequency bioelectrical impedance analyzer, the InBody S10 Biospace device (Biospace Co, Ltd, Seoul, Korea/Model JMW140), was used according to the manufacturer’s guidelines. 11 The patient was checked in lying position and the electrodes were attached in both ankles for legs and thumbs and middle fingers for arms during a free intake period before fasting by the same nutritionist. Body BCM, FM, FFM, and SM were obtained weekly using the InBody software from baseline until the end of treatment.…”

“…In our current study, we adopted bioelectrical impedance as another index reflecting the severity of LLL. Bioimpedance measurement is a noninvasive technology that can accurately measure a patient's TBW, ECW, and intracellular body water in clinical settings [19,20]. Specifically, InBody is widely used for the diagnosis of lymphedema and monitoring limb edema [21,22].…”
