Automation in anesthesia: computer controlled propofol infusion and data acquisition.

Area of Science:

• Anesthesiology
• Clinical Informatics
• Pharmacokinetics

Background:

• The Anesthesia Synchronization Software (ASYS) initially provided data acquisition from cerebral monitors and partial Target Controlled Infusion (TCI) control.
• Pharmacokinetic models are crucial for relating drug concentrations to infusion rates.

Purpose of the Study:

• To enhance the ASYS software by integrating hemodynamic monitoring and a full TCI system.
• To improve the precision and control of anesthetic drug administration during surgical procedures.

Main Methods:

• Implemented integration of hemodynamic monitoring data into the ASYS platform.
• Developed a full Target Controlled Infusion (TCI) system within ASYS.
• Utilized pharmacokinetic models to calculate and command infusion rates for anesthetic drugs.

Main Results:

• The enhanced ASYS software now incorporates real-time hemodynamic data.
• A fully functional TCI system is integrated, enabling precise control over infusion pumps.
• The system accurately determines drug infusion rates based on pharmacokinetic principles.

Conclusions:

• The improved ASYS software offers advanced control over anesthetic drug delivery by combining hemodynamic and TCI data.
• This advancement has the potential to enhance patient safety and optimize anesthetic management in clinical practice.
