Background In enhanced recovery protocols (ERP), a restrictive fluid regimen is proposed. Patients who undergo major surgery have an increased risk of post‐operative acute kidney injury (AKI). This combination may pose difficulties when ERP is used for patients undergoing major surgery. The aim of this study was to evaluate whether patients undergoing pancreatic surgery and treated with a restrictive fluid regimen are at greater risk of post‐operative AKI. Furthermore, if there was an increased risk of AKI, we aimed to identify its cause. Methods We reviewed the medical records of patients who underwent pancreatic surgery during 2014 (preERP, n = 58) and 2015 (ERP, n = 65). Fluid balance, the administration of cyclooxygenase‐2 inhibitors, creatinine levels and mean arterial pressure were recorded. The Kidney Disease: Improving Global Outcomes criteria were used to define AKI. Results The incidence of AKI was higher in the ERP group than in the PreERP group (12.5% vs. 1.8%, respectively, P = 0.035). The increased incidence of AKI could not be explained by differences in comorbidities, age, pre‐operative creatinine or perioperative hypotension. Administration of coxibs was higher in the ERP group and was associated with increased incidence of post‐operative AKI ( P = 0.018). The combination of coxibs and restrictive fluid regimen seems particularly harmful. Conclusion Pancreatic surgery with a restrictive fluid regimen carries an increased risk of post‐operative AKI if patients are also treated with cyclooxygenase‐2 inhibitors. It is therefore suggested that in protocols including a restrictive fluid regimen for open pancreatic surgery, the use of cyclooxygenase‐2 inhibitors should be avoided.
