PURPOSE To determine whether metabolic and hemodynamic parameters are "mathematically" coupled in rats submitted to portal triad occlusion following controlled hemorrhagic shock state. METHODS Pearson's coefficient (r-value) analysis was performed. Differences considered significant at p < 0.05 and -0.50 > r > 0.50. RESULTS It was observed that there is a direct proportional relationship to HCO3- with pCO2 (r = 0.66), base deficit (r = 0.87) and inverse with serum lactate (r = -0.54). pCO2 was directly associated with MAP (r = 0.51), and inversely with pH (r = -0.64). Hematocrit was directly associated with HR (r = 0.72) and CI (r = 0.76), and serum lactated was inversely associated with base deficit (r = -0.61). CONCLUSION In rats submitted to Pringle's maneuver during 15 minutes following hemorrhagic shock state, there is a mathematical coupling with a very good correlation between several hemodynamic and metabolic variables.
