Back­ground. In the assess­ment of ­fluid ­status ­after car­diac sur­gery, we ­applied bio­electrical impe­dance anal­ysis (BIA) to ­measure the ­total ­body ­water (TBW), extra­cel­lular ­fluid (ECF), and intra­cel­lular ­fluid (ICF), and eval­u­ated its ­validity.
­Methods. ­Thirty ­patients who under­went car­di­o­pul­mo­nary ­bypass (CPB ­group) and 19 sur­gical ­patients not ­receiving CPB (non-CPB ­group).
­Results. The ­change of BIA ­values (­ΔTBW, ­ΔECF, ­ΔICF), ­body ­weight and cumu­la­tive ­fluid bal­ance ­were deter­mined for 120 post­op­er­a­tive ­hours, and the rela­tion­ship ­between BIA ­values and ­body ­weight and ­fluid bal­ance ­were eval­u­ated. Post­op­er­a­tive ­changes in BIA ­values in the CPB ­group ­were com­pared ­with ­those in the non-CPB ­group. ­Finally the ECF/ICF ­ratio and hemo­dy­namic param­e­ters ­were com­pared. ­ΔTBW and ­ΔECF cor­re­lated ­with ­changes in ­body ­weight and ­fluid bal­ance, respec­tively. Espe­cially ­there was a ­high cor­re­la­tion in ­each ­case ­although ­large devi­a­tions in the ­slope of the regres­sion ­lines ­were ­observed. TBW and ECF ­increased ­from imme­di­ately ­after oper­a­tion up to 96 ­hours (the max­imum ­value was at day 2). On the ­other ­hand, ICF ­decreased ­from 48 to 72 ­hours ­after oper­a­tion. ­There ­were sig­nif­i­cant ­high ECF/ICF in the CPB ­group com­pared ­with the non-CPB ­group ­from 12 to 72 post­op­er­a­tive ­hours. We ­found ­that ECF/ICF cor­re­lated ­inversely ­with ­mean ­blood pres­sure, ­mixed ­venous ­oxygen sat­u­ra­tion and col­loid ­osmotic pres­sure, and pos­i­tively ­with cen­tral ­venous pres­sure and pul­mo­nary ­artery ­wedge pres­sure.
Con­clu­sions. It was con­sid­ered ­that BIA was ­useful for eval­u­ating the rel­a­tive ­changes in TBW and ­fluid dis­tri­bu­tion, and ECF/ICF ­might be a new param­eter for ­abnormal ­water metab­olism ­after car­diac sur­gery.
