Investigating the relationship between hemodynamic and metabolic parameters in portal triade occlusion following...

To determine whether metabolic and hemodynamic parameters are "mathematically" coupled in rats submitted to portal triad occlusion following controlled hemorrhagic shock state.

Pearson's coefficient (r-value) analysis was performed. Differences considered significant at p < 0.05 and -0.50 > r > 0.50.

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).

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.
