Influence of different qualitative composition of infusion solutions on cerebral hemodynamics in patients with acute...

The aim: Investigate the effect of 0.9% NaCl, HES 130, HAES-LX-5% and mannitol 15% on cerebral hemodynamics in patients with AIS.

Materials and methods: The study included 100 patients with AIS. As the investigated solutions were used: isosmolar 0.9% NaCl, hyperosmolar mannitol 15%, colloid-isoosmolar HES 130, colloid-hyperosmolar HAES-LX-5%. The control group received only 0.9% NaCl compared: 0.9% NaCl+HES 130, 0.9% NaCl+HAES-LX-5%, 0.9% NaCl+mannitol 15%. Evaluation of cerebral hemodynamic (indexes of cerebral blood flow) was performed using doppler ultrasound of cerebral arteries.

Results: The dynamics of specific volume velocity of blood flow per 100 grams of brain substance indicates that in the group of 0.9% NaCl and 0.9% NaCl+mannitol is the tendency to decrease the blood flow of the brain during 7 days of treatment, respectively: 2.8% and 7.5%. In patients with HES 130 solution cerebral blood flow increases by 14.2%, whereas when applied HAES-LX-5% during 7 days, it increases by 43.2% (p=0.004).

Conclusions: The analysis of the data of treatment the patients with AIS showed the best effect (p=0.004) of improvement of the cerebral circulation in the use of the polyfunctional infusion solution HAES-LX-5% unlike the 0.9% NaCl group and group of 0.9% NaCl+mannitol where was a decrease of the dynamics of cerebral blood flow, which could lead to hypoperfusion of the brain.
