The wECV\/TBW ratio was determined by \u2018classical\u2019 wrist\u2010to\u2010ankle whole body bioimpedance spectroscopy (wBIS); in addition, a novel whole body model (WBM) based on wBIS was used to predict normal hydration weight (NHW<jats:sub>WBM<\/jats:sub>).<\/jats:p><jats:p><jats:bold>Results:\u2003<\/jats:bold> Twenty\u2010one haemodialysis patients were studied; 11\u2003\u00b1\u20036 measurements were performed per patient. Nine patients reached DW<jats:sub>cBIS<\/jats:sub> (DW<jats:sub>cBIS<\/jats:sub> group), while 12 patients remained fluid\u2010overloaded (non\u2010DW<jats:sub>cBIS<\/jats:sub> group). Change in wECV as measured by wBIS accounted for 46\u2003\u00b1\u200323% in DW<jats:sub>cBIS<\/jats:sub> group, which was higher than in non\u2010DW<jats:sub>cBIS<\/jats:sub> group (33\u2003\u00b1\u200348%, <jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05) of actual weight loss at the end of study. In both groups the wECV\/TBW ratio did not change significantly between baseline and study end. Mean predicted NHW<jats:sub>WBM<\/jats:sub> at baseline was 3.55\u2003\u00b1\u20031.6\u2003kg higher than DW<jats:sub>cBIS<\/jats:sub>. The difference in DW<jats:sub>cBIS<\/jats:sub> and NHW<jats:sub>WBM<\/jats:sub> was 1.97\u2003\u00b1\u20031.0\u2003kg at study end.<\/jats:p><jats:p><jats:bold>Conclusion:\u2003<\/jats:bold> WBM could be useful to predict a target range of normal hydration weight particularly for patients with substantial fluid overload. The cBIS provides an accurate reference for the estimation of DW so that combined use of cBIS and WBM is promising and warrants further studies.<\/jats:p>","DOI":"10.1111\/j.1440-1797.2011.01526.x","type":"journal-article","created":{"date-parts":[[2011,9,28]],"date-time":"2011-09-28T01:45:50Z","timestamp":1317174350000},"page":"131-140","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Determination of fluid status in haemodialysis patients with whole body and calf bioimpedance techniques"],"prefix":"10.1111","volume":"17","author":[{"given":"LI","family":"LIU","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FANSAN","family":"ZHU","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JOCHEN","family":"G RAIMANN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"STEPHAN","family":"THIJSSEN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MURAT H","family":"SIPAHIOGLU","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GREGORY","family":"WYSTRYCHOWSKI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"THOMAS","family":"KITZLER","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CIRO","family":"TETTA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PETER","family":"WABEL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PETER","family":"KOTANKO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"NATHAN W","family":"LEVIN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,1,19]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"crossref","first-page":"1882","DOI":"10.1093\/oxfordjournals.ndt.a027898","article-title":"\u2018Dry weight\u2019 in dialysis: The history of a concept","volume":"13","author":"Charra B","year":"1998","journal-title":"Nephrol.
