Triple Anesthesia: Combining Sevoflurane, Propofol, and Remimazolam for General Anesthesia in a Case Series

Abstract

There is an ongoing quest for an ideal uniform anesthesia regimen that adequately covers all nociceptive stimuli preventing hypertension and tachycardia while minimizing hypotension and the need for antihypotensive drugs. Recently, the ultra-short-acting benzodiazepine remimazolam was approved for the induction and maintenance of general anesthesia. Combining remimazolam with sevoflurane and propofol may combine the antiemetic properties of propofol, the depressing (immobilizing) effect on spinal motor neurons of sevoflurane, and the hemodynamic stability afforded by remimazolam, making it an attractive addition to the armamentarium of anesthetic agents. We describe five patients in whom general anesthesia was maintained with this triple combination, along with multimodal analgesia. All patients maintained hemodynamic stability at sufficient hypnotic depth, with no observable movement during surgery or episodes of cardiac arrhythmias.
