Automated delivery of anesthesia using a closed-loop system

Anaesthesia Depth Consistency and System Performance of a Hermetic Closed-loop Anaesthesia Delivery System: A Randomized Controlled Study

Not applicable Interventional Sir Ganga Ram Hospital · NCT05967403

This study is testing a new automated system that delivers anesthesia for surgery by adjusting the medication based on the patient's brain activity to see if it makes the process safer and more efficient.

What this trial studies

This study evaluates a novel closed-loop anesthesia delivery system that automates the administration of propofol for total intravenous anesthesia (TIVA). By utilizing feedback from the patient's brain activity, measured through bispectral index (BIS), the system adjusts the dosage of propofol to maintain optimal anesthesia levels without human intervention. The goal is to enhance the efficiency and safety of anesthesia delivery during elective non-cardiac surgeries. Participants will be monitored to assess the system's performance compared to traditional methods.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 years, classified as ASA physical status I-II, who are undergoing elective non-cardiac surgery lasting at least 60 minutes.

Not a fit: Patients with uncontrolled cardiovascular diseases, neurological disorders, or those requiring postoperative ventilation may not benefit from this study.

Why it matters

Potential benefit: If successful, this system could lead to improved anesthesia management, reducing postoperative complications and enhancing recovery times for patients.

How similar studies have performed: Other studies have shown promise in automated anesthesia delivery systems, indicating potential for success with this innovative approach.
