CoreSys Monitoring for Intraoperative Stress Management in Abdominal Hysterectomy (CORESTRESS)
CoreSys Monitoring for Intraoperative Stress Management in Abdominal Hysterectomy: A Randomized Controlled Trial
This randomized controlled trial evaluates whether intraoperative guidance using the CoreSys monitor reduces the surgical stress response in patients undergoing elective open abdominal hysterectomy. Surgical stress involves complex hemodynamic, endocrine, and inflammatory responses that may negatively impact postoperative recovery.
Patients will be randomized to either anesthesia guided by conventional clinical and hemodynamic parameters or anesthesia additionally guided by CoreSys-derived indices of consciousness, nociception, and stress activity. The primary objective is to assess whether CoreSys-guided anesthesia attenuates stress biomarkers, including interleukin-6 (IL-6), cortisol and glycemia.

Descrizione dettagliata
Surgical trauma induces a neuroendocrine and inflammatory stress response characterized by activation of the hypothalamic-pituitary-adrenal axis and release of cytokines such as interleukin-6 (IL-6), a key mediator of acute-phase response and tissue injury severity.
Adequate intraoperative management of hypnosis and analgesia may attenuate this response. However, conventional monitoring relies mainly on indirect clinical and hemodynamic parameters. Advanced monitoring technologies, such as CoreSys, integrate electroencephalographic signals and heart rate variability to provide indices of hypnotic depth (BA), nociception/stress activity (SA), and an Trend of Sepsis and Inflammation (TSI).
This prospective randomized trial aims to determine whether anesthesia guided by CoreSys monitoring reduces intraoperative stress response compared to standard practice. Patients undergoing elective open abdominal hysterectomy will be randomized to either CoreSys-guided anesthesia or standard monitoring. Stress biomarkers (IL-6, cortisol and glycemia) will be measured perioperatively, along with intraoperative hemodynamic variability, anesthetic consumption, and early postoperative outcomes.

Sperimentale: CoreSys-guided anesthesia
Patients receive total intravenous anesthesia guided by standard clinical and hemodynamic parameters plus CoreSys monitoring indices (brain activity, stress activity, and response to inflammation).
Standard monitoring includes non-invasive blood pressure, electrocardiography, pulse oximetry, and capnography.
Anesthesia is adjusted according to these parameters.
|
Intravenous administration of propofol using target-controlled infusion (TCI) based on the Marsh pharmacokinetic model for induction and maintenance of general anesthesia.
A non-invasive monitoring device that integrates electroencephalographic and autonomic signals to assess hypnotic level, nociception, and intraoperative stress indices.
Intravenous administration of remifentanil using target-controlled infusion (TCI) based on the Minto pharmacokinetic model for intraoperative analgesia.

Comparatore attivo: Standard anesthesia
Patients receive total intravenous anesthesia guided by standard clinical and hemodynamic parameters.
Standard monitoring includes non-invasive blood pressure, electrocardiography, pulse oximetry, and capnography.
CoreSys monitoring is performed but not visible to the treating anesthesiologist and does not influence clinical management.
Data are recorded by a second investigator.
