METHOD FOR LOW-FLOW ANESTHESIA BASED ON SEVOFLURANE WITH APPLICATION OF EPIGLOTTIC I-GEL DUCT Russian patent published in 2017 - IPC A61K31/15 A61K31/45 A61P23/00 

FIELD: medicine.

SUBSTANCE: induction into anesthesia is carried out by intravenous injection of 1% propofol solution at a dose of 1.5-2 mg/kg, up to 200 mg, and 0.005% fentanyl solution at a dose of 0.7-1 μg/kg. After reaching a sufficient depth of anesthesia with BIS 40-50 units, an epiglottic I-gel duct, a gastric tube through a special port on the duct are installed and the patient is transferred to lung ventilation in auxiliary modes: SIMV, PS; anesthesia is maintained by inhalation administration of sevoflurane at a dose of 1-2 volume percent with fresh gas flow of 0.8-1.2 l/min, via a semi-enclosed loop using a adsorber with soda lime; sevoflurane concentration is selected till a steady achievement of 0.6-0.8 MAK, analgesia is provided by intravenous administration of 0.005% solution of fentanyl; infusion therapy is carried out with physiological solution in a dose of 500-700 ml.

EFFECT: adequate level of sedation and analgesia, reduced time of anesthesia, reduced drug burden on the body, and a lower risk of anesthesia complications.
