[Osmolality of contrast media--a risk factor in radiological endovascular procedures in children].

The study was conducted in 90 children aged from 5 months to 14 years during radiologically-guided endovascular (RIV) interventions with bolus injection of radiocontrast agents (RCA) in a dose of 2-3 ml/kg for 2-3 sec. High-osmolality RCA were used in 80 children, an nonionic low-osmolality RCA omnipaque-300 in 10 children. Injection of RCA bolus was attended by marked acute disorders of blood colloidoosmotic equilibrium (COE) which depended on the initial status of the latter and were greater when high osmolality RCA were used.

[The effect of hyperbaric oxygenation on the osmotic status of children with surgical pathology of the abdominal organs].

The effect of hyperbaric oxygenation (HBO) on blood osmolality has been studied in children with abdominal pathology. It has been shown that HBO has a considerable effect on blood osmolality evident both during and after the HBO session. To prevent possible HBO-induced disturbances of blood osmolality special pretreatment with ten infusion solutions has been suggested.
