E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Patients requiring general anaesthesia for surgery using propofol and requiring an arterial line for invasive blood pressure monitoring as part of their clinical care. |
|
E.1.1.1 | Medical condition in easily understood language |
Patients requiring general anaesthesia for surgery using propofol and requiring an arterial line for invasive blood pressure monitoring as part of their clinical care. |
|
E.1.1.2 | Therapeutic area | Analytical, Diagnostic and Therapeutic Techniques and Equipment [E] - Anesthesia and Analgesia [E03] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
We hypothesize that online adaptation or tuning of the population PKPD model of propofol will decrease the residual error between predicted and measured plasma-concentrations during maintenance of anaesthesia, when the adapted PKPD models are used to calculate propofol infusion rates required for the target concentrations set by the responsible anaesthetist. |
|
E.2.2 | Secondary objectives of the trial |
Secondly, we will compare the hypnotic and haemodynamic stability before and after the adaptation as measured by EEG and other vital signs clinical monitoring (heart rate, blood pressure). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Age between : 18 years and 75 years
- Informed patient consent
- ASA Class (American Society of Anesthesiologists physical status) I- III
- scheduled for elective surgery under general anaesthesia with propofol and requiring an arterial line for invasive blood pressure monitoring as part of their clinical care will be enrolled.
|
|
E.4 | Principal exclusion criteria |
potential subject who meets any of the following criteria will be excluded from participation in this study:
• patient refusal
• CNS diseases (dementia, CVI, seizures, psychiatric diseases)
• Regular intake of CNS active drugs (benzodiazepines, antidepressants,
antipsychotics, anticonvulsants)

E.5 End points |

2 years after last inclusion |
|
E.5.2 | Secondary end point(s) |
The hypnotic and haemodynamic stability pre- and post- adaptation as measured by EEG and other vital signs clinical monitoring (heart rate, blood pressure). |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
2 years after last inclusion |
