COMPARATIVE EVALUATION OF VARIOUS OPTIONS FOR MULTIMODAL PERIOPERATIVE ANALGESIA IN TOTAL LARYNGECTOMY
Abstract
Adequate anesthesia management for total laryngectomy requires a reasonable balance between the appropriate use of opioids and the avoidance of harm associated with them.
Aim: comparative evaluation of various options for multimodal perioperative analgesia and search for optimal methods of anesthesia for total laryngectomy.
Materials and methods: The study was conducted with the involvement of 100 patients with T3-4N0-3M0 laryngeal cancer who underwent total laryngectomy: Group I (n=25) received classical anesthesia with standard doses of opioid analgesics; Group II (n=25) received an additional infusion of lidocaine; Group III (n=25) received an additional infusion of dexmedetomidine; Group IV (n=25) received an infusion of both lidocaine and dexmedetomidine. Parameters of the cardiovascular and respiratory systems, BIS and ANI data were recorded at 8 stages of surgery. Statistical analysis was carried out using the methods of descriptive and analytical statistics using the STATISTICA v.6.1 software product (Statsoft Inc., USA, license no. AGAR909E415822FA).
Results and discussion: When used as adjuvant components of anesthesia, lidocaine (Group II), dexmedetomidine (Group III), or their combination (Group IV), compared with standard analgesia (Group I), there was an acceleration of awakening, an increase in the time of postoperative analgesia, and a significant decrease in intraoperative analgesics (p<0.001). In group IV, a statistically significantly (p<0.05) better result was observed according to the BIS and ANI indices. Despite a certain tendency to hypotension and bradycardia, the use of lidocaine and dexmedetomidine maintained the stable state of systemic hemodynamics.
Conclusions: A comparative evaluation of various schemes of anesthesia for total laryngectomy showed the feasibility of multimodal anesthesia and opioid-limiting anesthesia with the combined use of lidocaine and dexmedetomidine.
Key words: laryngeal cancer, total laryngectomy, multimodal analgesia, low-opioid anesthesia.
