Summary
The development of target effect-site controlled concentrations (TCI) of remifentanil have gained increasing acceptance during cardiac surgery as regarding the resulting of hemodynamic stability and early extubation. The use of low-dose opioid technique has been progressively used nowadays because of its ceiling effect to attenuate cardiovascular responses to noxious stimuli. We hypothesize that the use of low target remifentanil effect site concentrations may provide comparable shorter times to tracheal extubation and hemodynamic stability to the use of high remifentanil Ce during target-controlled propofol anesthesia for cardiac surgery.
