The Carola computer system enhances open heart surgery by automatically documenting patient data and vital signs. This system improves therapeutic decisions and has been successfully used for over 12,500 anesthetic hours.

Area of Science:

  • Medical Informatics
  • Cardiothoracic Surgery

Background:

  • Open heart surgery requires comprehensive patient data acquisition and documentation.
  • Existing methods may lack real-time data integration and efficient storage.
  • Anesthetic record-keeping is crucial for patient safety and therapeutic decision-making.

Purpose of the Study:

  • To design and implement a computer system for real-time data acquisition and documentation during open heart surgery.
  • To evaluate the system's usability and impact on clinical decision-making.
  • To establish a database for long-term storage and statistical analysis of surgical data.

Main Methods:

  • Development of the 'Carola' computer system utilizing modular hardware (Motorola 6809 microprocessors) and Pascal software.
  • Integration of over 50 analogue/digital signals from monitoring racks, ventilators, and heart-lung machines.

Related Experiment Videos

  • Implementation of a menu-driven user interface for anesthetic nurses and anesthesiologists, with data plotted and stored on cassette tapes for database transfer.

    • Main Results:

    • The Carola system successfully processed patient data, plotting over 50 signals and offline data in real-time.
    • User feedback indicated easy learning and fast data entry, facilitating therapeutic decisions.
    • Over 12,500 anesthetic hours were documented, achieving near 100% documentation in the cardiothoracic unit since 1983.

    Conclusions:

    • The Carola computer system provides efficient and comprehensive documentation for open heart surgery.
    • The system's design and user interface led to high user acceptance and improved clinical decision support.
    • The established database enables valuable statistical processing of extensive surgical data.
