[Changes in cerebral and peripheral plethysmograms in the early postoperative period of patients with supratentorial tumors]. / Izmeneniia mozgovoi i perifericheskoi pletizmogramm v rannem posleoperatsionnom periode u bol'nykh s supratentorial'nymi opukholiami.

Cerebral and peripheral plethysmograms were studied in the early postoperative period in 76 patients with supratentorial tumors. Their simultaneous recording, appraisal of the pronounced character of the pulse, respiratory, and irregular oscillations and waves of the 3rd order, their changes in dynamics make it possible to judge the state of cerebral circulation and draw prognostic conclusions. The character of correlation of cerebral and peripheral plethysmograms, particularly in the synchronism and direction of the waves of the 3rd order, attests to the intactness of disorders of autoregulation of the cerebral blood flow.

[Use of the hemodilution method in neurosurgery]. / Primenenie metoda gemodiliutsii pri neirokhirurgicheskikh operatsiiakh

The results of surgical interventions conducted with haemodilution in 31 patients with brain tumours permit to conclude that in comparison with the routine transfusion methods (25 cases) this technique has several advantages in terms of correction of the disorders in the electrolyte and protein composition of the blood, and maintenance of these parameters on a safe level during the postoperative period. A beneficial effect of this method upon the circulating blood volume and on its rheological properties was observed, which improved the conditions of microcirculation.
