The aim of the research is to evaluate the informativeness of methods for assessing analgesia qNOX and ANI level. Material and methods. The study included 24 patients who were operated on the spine under general anesthesia. The patients were divided into 2 groups; in 12 patients the level of analgesia was assessed using qNOX index, and in 12 patients using ANI index. Hemodynamic parameters were assessed in patients, among them: blood pressure and heart rate. Statistical analysis was carried out using Statistica 20.0 Software package. Results. Intravenous dose of fentanyl of 2.4 ± 0.4 μg / kg made it possible to reach ANI 50 level in 4.2 ± 0.6 minutes since the moment of its administration. At stage II, ANI reached 65. After intravenous fentanyl administration qNOX reached 39 in 4.1 ± 0.5 min. At stage II, 15.3% of qNOX decrease was noted. Conclusion. qNOX and ANI values are equally objective criteria for the adequacy of analgesia, objectively reflecting the achieved level of nociceptive protection
