Abstract

 


During the last few years it has been shown that osmolality more than hydrostatic or oncotic pressures effects the water movements' trough the blood brain barrier. The goal of the present study was to compare the effect on plasma osmolality of the infusion of different currently used solutions. Patients scheduled for lumbar intervertebral disc surgery received either NaCl %0.9, Ringer Lactate Dextrose 5% or Hydroxyethyl- Starch 10%. All of the selected solutions maintain plasma osmolality. We did not find any statistically different plasma osmolality changes between groups. We must take into account that dextrose in Ringer Lactate is harmful for patients cerebral ischemia susceptible.
