This study aims to determine the optimal effect-site concentration of fentanyl using a computer-assisted continuous infusion system for tracheal intubation during CABG surgery.
Optimal fentanyl dosing for CABG intubation remains undefined; leaves open targeted infusion validation before clinical adoption.
The computer-assisted continuous infusion (CACI) system was developed to more rapidly attain and to maintain stable effect-site fentanyl concentrations as compared with the intermittent injection method. The CACI system allows the anesthesiologist to control effect-site fentanyl concentrations during various surgical stimuli during cardiac anesthesia. This system can rapidly control the depth of anesthesia and compensate for the disadvantages of IV anesthesia. Early patient recovery also enables early tracheal extubation, which is an important component of the "fast track" cardiac surgery pathway. In this study, the use of a target-controlled infusion of low-dose propofol was combined with the target-controlled infusion of fentanyl for patients undergoing coronary artery bypass graft surgery. The purpose of this study was to evaluate the proper effect-site concentration of fentanyl for the tracheal intubation of patients undergoing coronary artery bypass graft surgery.
