Randomized Controlled TrialComparison of anesthesia effects between closed-loop and open-loop target controlled infusion of propofol using the bispectral index in abdominal surgery.
Bispectral index (BIS) can reflect the depth of propofol sedation. This study aims to compare the anesthetic satisfaction, anesthetic dose, and hemodynamic changes between closed-loop target controlled infusion (CLTCI) and open-loop target controlled infusion (OLTCI) during abdominal surgery. ⋯ Compared with propofol OLTCI, anesthesia with propofol CLTCI under BIS guidance can maintain a more appropriate depth of anesthesia sedation and more stable hemodynamics.
