Evaluation of a Novel Closed-loop Propofol and Remifentanil System Guided by Bispectral Index Compared to a TCI Open-loop System: a Randomized Controlled Trial.
In Brief
A Phase 3 clinical trial evaluating Closed-Loop propofol and remifentanil system by Bispectral Index, Open-Loop propofol and remifentanil by Target Controlled Infusion, and 1 other intervention for Anesthesia, General and Anesthesia, Intravenous. Completed, enrolled 150 participants across 1 site.
Detailed Summary
Closed loop system in intravenous anesthesia is more effective to maintain depth of anesthesia compared with manual system open, it is unclear what driver and variables to achieve this goal be more physiological; in the literature doesn´t exist studies showing that the closed-loop system for both hypnotic and opioid is better than the controlled pharmacokinetic models and open loop system (target controlled infusion-TCI) to maintain anesthetic depth. In addition, the infusion of the opioid lacks physiological controllers in closed loop. Thus, a system was designed for intravenous anesthesia in closed loop for propofol as hypnotic based on neuromonitoring bispectral index as anesthetic depth, and was integrated an additional closed system for remifentanil using hemodynamic variables and control algorithm associated with bispectral index. The purpose of this study is to determine the therapeutic effectiveness of a new system of administration of intravenous anesthesia in closed loop to maintain a depth of anesthesia compared to an open loop system TCI.
