[Effects of small volume resuscitation on the hemodynamics and extravascular lung water of septic shock dogs].
OBJECTIVE
To observe the effect of small volume resuscitation by hypertonic-hyperoncotic solution on the hemodynamics and extravascular lung water of septic shock dogs.


METHODS
Lipopolysaccharide of E. coli was injected to 24 healthy dogs via femoral vein to induce septic shock. These septic shock dogs were resuscitated with hypertonic salt solutions (HS, 6 ml/kg, n = 6), 6% hydroxyethyl starch in combination with HS (HSS, 6 ml/kg, n=6), normal saline (NS, 100 ml/kg, n=6), and 6% hydroxyethyl starch solutions (HES, 33 ml/kg, n=6), respectively. The changes of hemodynamics and extravascular lung water were observed.


RESULTS
After resuscitation, all the solutions improved the hemodynamics of septic shock dogs with significant differences (P<0.05). The effects were superior in HS group and HSS group when compared with in NS group. The extravascular lung water increased in NS group, while no obvious changes were found in the other three groups.


CONCLUSIONS
All these four solutions can improve the hemodynamics of septic shock dogs. Small volume hypertonic-hyperoncotic solution has a similar effect in hemodynamics as NS, HS, and HES. Meanwhile, it does not increase the extravascular lung water.
