Efficacious multimodal analgesia and anesthesia are the basis of successful fast-track surgery. These multidrug regimens aim at decreasing postoperative pain, intra- and postoperative opioid requirements, and subsequently, opioid-related adverse effects and to fasten recovery. Opioid-free postoperative analgesia has been recommended for more than 10 years. Opioid-free anesthesia (OFA) is based on the idea that hemodynamic stability can be achieved without opioids during anesthesia. OFA is multimodal anesthesia associating hypnotics, N-methyl-D-aspartate (NMDA) antagonists, local anesthetics, anti-inflammatory drugs and alpha-2 agonists (Dexmedetomidine).
