Background This study evaluates the short-term impact of fluid administration during gastrectomy for cancer. Methods A multi-institutional database of patients undergoing gastrectomy for cancer from three tertiary centers was reviewed. Logistic and linear regression analyses were performed. Results 205 patients were included. The majority of patients (n = 116, 57%) underwent proximal or total gastrectomy. Median anesthesia time was 280 min (range 95–691 min). Median intraoperative crystalloid administration was 2901 ml (range 500–10,700 ml). Median colloid administration was 0 (range 0–3835 ml), although only 66 patients (32%) received colloid. On multivariate analysis, patients who received <10.0 ml total fluid per minute of anesthesia had a significantly higher risk of complications (OR 4.12, p = 0.010). Crystalloid and total fluid administration ratios did not significantly affect LOS or discharge disposition. Conclusions Restricting intra-operative fluid resuscitation to <10 ml total fluid per minute anesthesia is associated with an increased risk of complications in patients undergoing gastrectomy for cancer.
