Box plot for serum BNP levels of all 209 patients who underwent hepatectomy after implementation of the brain natriuretic peptide (BNP)-guided hepatobiliary fluid protocol (2014–2016). The y-axis scale is changed to highlight the therapeutic range in which changes to fluid balance can be made based on serum BNP levels. From postoperative day 0 to day 5, BNP was >200 pg/ml or < 100 pg/ml an average of 75% of the time.
