✦ Synopsis
Summary Oesophageal Doppler monitoring allows non‐invasive estimation of stroke volume and cardiac output. We studied the impact of Doppler guided fluid optimisation on haemodynamic parameters, peri‐operative morbidity and hospital stay in patients undergoing major bowel surgery. Fifty‐seven patients were randomly assigned to Doppler (D) or control (C) groups. All patients received intra‐operative fluid therapy at the discretion of the non‐investigating anaesthetist. In addition, Group D were given fluid challenges (3 ml.kg^−1^) guided by oesophageal Doppler. Group D received significantly more intra‐operative colloid than Group C (mean 28 (SD 16) vs. 19.4 (SD 14.7) ml.kg^−1^, p = 0.02). Cardiac output increased significantly for Group D whilst that of controls remained unchanged. The mean difference between the groups in final cardiac output was 0.87 l.min^−1^ (95% confidence interval 0.31–1.43 l.min^−1^, p = 0.003). Five control patients required postoperative critical care admission. Fluid titration using oesophageal Doppler during bowel surgery can improve haemodynamic parameters and may reduce critical care admissions postoperatively.
