BackgroundFluid therapy in the perioperative period varies greatly between anesthesia providers and may have a negative impact on surgical outcomes.MethodsWe conducted a retrospective analysis of 705 elective colorectal cases consisting of colectomies, ileocolic resections, and low anterior resections at an academic institution from January 1, 2010 to May 29, 2015, collected by our electronic medical record before implementation of Enhanced Recovery After Surgery (ERAS®) pathways.ResultsThe mean for total crystalloid administration was 2578 mL with a standard deviation (SD) that was approximately 50% of the mean value. A combination of both normal saline and lactated Ringer's solution was used in almost all cases without a clear rationale for fluid choice. Fluid administered to patients was disproportional to measured intraoperative fluid losses (estimated blood loss and urine output) by a factor of 10. The average rate of fluid given was 1050 mL/h with an SD of nearly the same amount (951 mL). There was a variability of over 67% in total crystalloid administered based on both ideal body weight and total body weight.ConclusionsWe found that a wide variability in the amount and type of fluid therapy administered existed at our institution before implementation of a colorectal ERAS pathway or routine use of goal-directed fluid therapy (GDFT). ERAS pathways with GDFT protocols could lead to more rational and consistent fluid therapy leading to improved outcomes.
