Abstract
We examined the relationship between measured colloid osmotic pressure (COP), and COP calculated from serum total protein concentration (TP). Serum COP and TP were measured in 40 patients with severe abdominal sepsis. Measured COP values were not significantly different from values calculated using three separate formulas. The correlation rate between measured COP and TP (r = .83, p < .01) was lower than that between calculated COP and TP (r = .99, p < .01). All three formulas were fairly reliable. Alternatively, a table of predicted COP values may be useful in severely ill patients.Keywords
