Post-operative nausea and vomiting (PONV) represents a serious and vexing problem after bariatric surgery. We hypothesized that liberal administration of IV fluid administration may influence PONV.
50 patients were recruited from a bariatric surgery clinic in an academic hospital.

Outcomes measured included urine output, creatinine, and nausea scores by Visual Analogue Score. Observers were blinded to which IV fluid regimen was employed. Categorical and continuous variables were compared by Chi-Square and T- test respectively with P
