Clinical significance of detecting body fluid volume and distribution using human body composition analyzer among perioperative patients

Objective To explore the meaning and clinical value of detecting body fluid volume and distribution using human body composition analyzer among perioperative patients. Methods This study was conducted using the cross-sectional research method. A total of one hundred and twenty-three patients who underwent abdominal surgery in Binzhou Medical University Affiliated Hospital from March to August 2016 were enrolled. The volume of intracellular water (ICW), extracellular water (ECW) and total body water (TBW) was detected by Inbody S10 1 d before operation (PreD1) and 1, 3, 5, 7 postoperatively (POD 1, 3, 5, 7). Furthermore, the effects of ECW/TBW on white blood cells, hemoglobin, albumin and clinical prognosis on POD 1 were analyzed. Results ICW, ECW, and TBW were increased in the early stage of postoperation. On POD 1, ICW/TBW reached the lowest level, ECW/TBW reached the highest, and then gradually recovered to normal. The lower the level of hemoglobin and albumin in patients, the higher the ratio of ECW/TBW (>0.400). The longer the time of postoperative abdominal drainage and hospital stay, the higher the incidence of postoperative complications and mortality. Conclusions The measurement of body fluid content in the perioperative period has important guiding value for evaluating the prognosis of the patients and reducing the postoperative complications. As a reliable tool, human body composition analyzer has important clinical significance. Key words: Body fluids; Body fluid compartments; Component analysis
