Propofol Pharmacokinetics and Pharmacodynamics Modelling

"The whole anaesthetic procedure is standard except for additional body composition assessment with Body Composition Monitor - BCM (Fresenius Medical Care, Germany) and arterial blood samples collection.~In all included patients, propofol will be started at 2000mg/h until LOC, defined by loss of eye-lash reflex and loss of response to name calling. During surgery propofol infusion will be guided by targeted BIS values between 40 and 60.~Arterial blood samples will be obtained immediately after LOC and after every 20-30 minutes during propofol infusion. After stopping propofol infusion, arterial blood samples will be acquired every 10 minutes until recovery of consciousness. The maximum blood sample per patient will be 20 mL."
