A new software, ASYS, aids anesthesiologists by acquiring real-time data for Target Controlled Infusion (TCI) and monitoring patient brain signals during surgery. It enhances anesthesia management and patient safety.

Area of Science:

  • Anesthesiology and Perioperative Medicine
  • Biomedical Engineering
  • Clinical Informatics

Background:

  • Target Controlled Infusion (TCI) systems require real-time data for effective drug delivery during anesthesia.
  • Supervisory Control And Data Acquisition (SCADA) principles can be adapted for clinical settings to improve patient monitoring.
  • Anesthesiologists need advanced tools to manage complex drug infusions and patient physiological responses.

Purpose of the Study:

  • To develop and present a novel software, ASYS, for real-time data acquisition and control in a clinical anesthesia setting.
  • To integrate TCI monitoring and patient brain signal acquisition within a single supervisory software.
  • To provide anesthesiologists with a reliable tool for managing anesthesia and ensuring patient safety.

Main Methods:

Related Experiment Videos

  • Development of a software system (ASYS) inspired by industrial SCADA principles.
  • Real-time data acquisition from surgical room devices, including infusion pumps and patient brain signal monitors.
  • Integration of pharmacokinetic models to relate drug concentrations with infusion rates.

Main Results:

  • The ASYS software successfully acquires and displays real-time data, including patient brain signals.
  • The system provides calculated infusion rates based on pharmacokinetic models, serving as commands for infusion pumps.
  • The software acts as a supervisory tool, supporting anesthesiologist decision-making without fully automating control.

Conclusions:

  • The ASYS software is a valuable tool for anesthesiologists, enhancing the management of TCI and patient monitoring.
  • The integration of pharmacokinetic modeling and real-time data acquisition improves the safety and balance of anesthesia.
  • This development represents a significant step towards advanced clinical informatics in surgical environments.
