Solute equilibrium over the extracellular fluid space in haemorrhagic hypotension: a study in a cannulated thoracic duct model.
Haemorrhagic hypotension, 50 mm Hg, has been inflicted on non-starved rats. Osmolar and solute developments have been followed in lymph and arterial plasma to assess diffusion and equilibration characteristics of the initial stages of haemorrhage. Lymph flow changes have reflected an intracellular fluid mobilization to the interstitium, caused by an osmotic gradient due to the elevated levels of glucose. A fluid homeostatic effect of pseudodiabetes associated with stress and haemorrhage is postulated.
