NPO Time Compared to Fluid Requirements by Goal-Directed Fluid Therapy. Regression lines for twelve different approaches to fluid-administration estimation. Each row represents a different calculation of amount administered: top row – total ml; middle row – ml/hour; bottom row – ml/kg/hr. The first column shows treatment of crystalloid to colloid on a 1:1 basis. The second column shows treatment of crystalloid to colloid on a 3:1 basis. The third and fourth column are again 1:1 and 3:1 treatment, but instead of total amount administered look instead at fluid balance (amount administered minus urine output and blood loss). None of the regressions indicate a significant relationship between longer NPO time and higher fluid requirements by GDFT protocol
