Pharmacotherapy Personalization of Cancer Patients

The oncologic patients are qualified to head and neck tumor resection in general anesthesia. The anesthesia introduction is performed with single dose of midazolam, fentanyl, rocuronium and propofol/etomidate. Sevoflurane is used in anesthesia maintenance. Patients are transported to ICU after operation. Then they are kept for several hours in analgosedation. All used drugs are given by intravenous continuous infusion. Oxycodone is an analgesic component of analgosedation. Midazolam, dexmedetomidine and/or propofol are used as sedatives (2-3 drugs in every patient). Whole blood samples (2.0 ml) are collected during the study to measure drugs concentrations - 3-4 times during infusion, 5, 10, 15, 30, 60 minutes and 2, 4, 6 hours after the infusion cessation. Vital parameters and bispectral index are monitored during analgosedation and 6 hours after the infusion cessation and noted every 15-60 minutes.
