Abstract
Objective. To study the impact of separate anesthesiological procedures on cerebral oxygenation on stages of transduodenal endoscopic operative interventions in patients, suffering obturation jaundice.
 Маterials and methods. A monitoring investigation for the cerebral oxygenation state was conducted in patients of three investigated groups in conditions of various procedures of general anesthesia. Моnitoring of cerebral oxygenation was done, using the monitoring system, named INVOS 500B. In patients of Group I the intravenous general anesthesia with propofol and fentanyl in conditions of a secured spontaneous respiration with the oxygen inhalation was applied; in patients of Group II - intravenous general anesthesia, using propofol, fentanyl and atracurium besylate in conditions of a controlled mechanical ventilation (СМV) via a standard endotracheal tube; in patients of Group III - a deep analgosedation, using propofol and fentanyl in conditions of supportive pulmonary ventilation in a regime of synchronized intermittent mandatory ventilation (SIMV) via gastrolaryngeal tube.
 Results. In patients of Group I on the main stage of the operative intervention the cerebral oxygenation index (rSpO2) have lowered by 24.2% respectively initial value and by 37.8% - repectively the value while beginning of the operation. In patients of Groups ІІ and ІІІ a controlled index on all stages of the operation persisted stable.
 Conclusion. Advantage must be given to general anesthesia in a SIMV pulmonary regime via gastrolaryngeal tube.
