[CONTINUOUS HEMOGLOBIN MONITORING USING PULSE CO-OXIMETRY IN CARDIAC SURGERY.].

The Aim: To assess the accuracy ofcontinuous hemoglobin monitoring using pulse co-oximetry and revealfactors affecting the results of the measurements during early postoperative period in cardiac surgery.

Materials And Methods: 27 patients undergoing off-pump CABG and 16patients after elective complex (repair or replacement of two or more valves) or combined (valve and coronary artery) cardiac surgery requiring CPB were enrolled into a prospective observational study. Both groups received continuous hemoglobin monitoring using pulse co-oximetry (SpHb).

Continuous Monitoring of Lactate Using Intravascular Microdialysis in High-Risk Cardiac Surgery: A Prospective Observational Study.

Objective: To assess the accuracy and applicability of a novel system, not requiring calibration, for continuous lactate monitoring with intravascular microdialysis in high-risk cardiac surgery.

Design: Single-center prospective observational study.

Setting: City Hospital #1 of Arkhangelsk, Russian Federation.

[Choice of optimal perfusion flow rate during surgical correction of combined acquired heart diseases].

Cardiac output during the use of cardiopulmonary bypass (CPB) is defined by perfusion flow rate, which is calculated by multiplying the perfusion index (PI) on the body surface area. To date, there is no clear definition of an optimal PI and flow rate of perfusion. 60 patients operated with CPB were enrolled in the prospective study to determine the relations between different modes of perfusion and oxygen transport during surgical correction of combined valvular heart disease.

Monitoring of anesthetic depth during surgical correction of acquired valvular disorders: single center, randomized trial.

Objective: The authors' primary objective was to test the hypothesis that Cerebral State Index (CSI)-guided control of anesthetic depth might reduce the consumption of anesthetics and shorten the duration of ICU and hospital stays after surgical correction of combined valve disorders.

Design: Single center, randomized trial.

Setting: City Hospital Number 1 of Arkhangelsk, Russian Federation.

Normothermic cardiopulmonary bypass increases cerebral tissue oxygenation during combined valve surgery: a single-centre, randomized trial.

Objectives: In cardiac surgery, the choice of temperature regimen during cardiopulmonary bypass (CPB) remains a subject of debate. Hypothermia reduces tissue metabolic demands, but may impair the autoregulation of cerebral blood flow and contribute to neurological morbidity. The aim of this study was to evaluate the effect of two different temperature regimens during CPB on the systemic oxygen transport and the cerebral oxygenation during surgical correction of acquired heart diseases.
