Pharmacokinetic and Pharmacodynamic Modelling of Norepinephrine in Patients Under Target Controlled Infusions (TCI) for Anaesthesia

Currently, administration of norepinephrine diluted at 5 µg/ml bolus or continuous infusion is common during sympatholysis hypotension of TCI following the elimination of hypovolemia or anesthetic overdosage. Continued intravenous administration must meet hemodynamic goals within a narrow time frame. Depending on the intensity of hypotension the dosage is variable. It is adjusted in real time while it is excessive or insufficient at times. Therefore, the development of modeling should predict the kinetic and hemodynamic effects based on dosage and individual.
