title: Interactive technology in obstetric anaesthesia and analgesia: exploring seamless solutions to jagged problems.
abstract: Perioperative care often involves treating rapid changes in a patient's physiological profile that requires timely intervention by anaesthetists. Interactive technology and closed-loop systems are currently developed in obstetric anaesthesia and analgesia for maintaining parameters during caesarean section and epidural analgesia. This review discusses the principles of interactive systems and the use of patient feedback to integrate these interactive systems. The components of an interactive system such as the input sensor or device, microprocessor-based control unit and the effector are introduced. Developments in continuous, non-invasive blood pressure monitoring, control algorithms and smart pump technology would help to redefine how technology can assist obstetric anaesthetists to provide better care and improve clinical outcomes for pregnant women.
