The Influence of Perioperative Fluid Therapy on N-terminal-pro-brain Natriuretic Peptide and the Association With Heart and Lung Complications in Patients Undergoing Colorectal Surgery: Secondary Results of a Clinical Randomized Assessor-blinded Multicenter Trial

Objective: To investigate the influence of intravenous (iv) fluid volumes on the secretion of N-terminal-pro-brain natriuretic peptide (NT-Pro-BNP) in colorectal surgical patients and its association with cardiopulmonary complications (CPC). In addition, to examine if preoperative NT-Pro-BNP can predict the risk for postoperative CPC. Methods: Blood samples from patients enrolled in a previously published clinical randomized assessor-blinded multicenter trial were analyzed.1 Included were adult patients undergoing elective colorectal surgery with the American-Society-of-Anesthesiologists-scores of 1–3. Samples from 135 patients were available for analysis. Patients were allocated to either a restrictive (R-group) or a standard (S-group) iv-fluid regimen, commencing preoperatively and continuing until discharge. Blood was sampled every morning until the fourth postoperative day. The primary outcome for this study was NT-Pro-BNP changes and its association with fluid therapy and CPC. Results: The S-group received more iv-fluid than the R-group on the day-of-surgery [milliliter, median (range) 6485 (4401–10750) vs 3730 (2250–8510); P
