Bioelectrical Impedance Analysis for Preoperative Volemia Assessment in Living Donor Hepatectomy

Abstract

Donor safety remains an important concern. We introduced preoperative bioelectrical impedance analysis (BIA) in living donor hepatectomy, as it is a practical method for volemia assessment with the advantages of noninvasiveness, rapid processing, easy handling, and it is relatively inexpensive. We analyzed 51 living donors who underwent right hemihepatectomy between July 2015 and May 2022. The ratio of extracellular water:total body water (ECW/TBW; an index of volemic status) was measured. ECT/TBW p p = 0.045) and decreased operative duration (240.5 ± 45.6 vs. 276.5 ± 54.0 min, p = 0.016). A cleaner surgical field (surgical field grade 1) was significantly associated with decreased operative duration (p = 0.001) and estimated blood loss (p p = 0.007). In conclusion, preoperative volemia assessment using BIA can improve operative outcomes by creating a favorable surgical environment in living donor hepatectomy.
