“…To improve the course of the perioperative period in patients with degenerative spine diseases, the following methods of anesthesia support are proposed: inhalation anesthesia [31], combined anesthesia with methadone and ketamine [32], combinations of ketamine and propofol [33], spinal anesthesia with bupivacaine [34]. A high opioid-saving effect and a small number of anesthesia-related complications are observed in the combination of minimally invasive surgical techniques with multimodal analgesia [35], intravenous sedation [36], or local anesthesia [37]. According to the systematic analysis of 31 randomized clinical studies, the reliable efficacy of the perioperative analgesia is achieved by using nonsteroidal anti-inflammatory drugs, COX-2 inhibitors, ketamine, and epidural analgesia [38], whereas an application of gabapentin and methadone is associated with a high risk of adverse drug effects and the efficacy of using local anesthetics, dexmedetomidine, glucocorticoids has not been validated [38].…”
