Non-opioid analgesics: New opportunities in early rehabilitation of patients with gynecological cancer.

Abstract

e17129 Background: An important principle of analgesia is its effect on each component of the pain formation. The purpose of the study was to improve analgesia in the perioperative period in patients with gynecological cancer. Methods: This prospective randomized study of the quality and effectiveness of various analgesics included 97 patients aged 22-67 years receiving surgery for gynecological cancer. The patients were divided into two groups. Group 1 (n = 47): patient-controlled analgesia with trimeperidine and nonsteroidal anti-inflammatory drugs (NSAIDs); group 2 (n = 50): preemptive analgesia based on lidocaine, magnesium sulphate, nefopam and NSAIDs. Results and pain syndrome were assessed by levels of glucose, cortisol, insulin, lactate, C-reactive protein (CRP), Kerdo autonomic index, visual analogue scale (VAS), levels of personal and reactive anxiety and depression. Results: Analgesic effect of trimeperidine was obtained in 83.3% (p < 0.05). However, the effect was less pronounced, compared to non-opioid analgesics, and did not reduce the psychosomatic component of pain after surgical treatment. In group 2, non-opioid analgesia limited the increase of cortisol, glucose, insulin, CRP and lactate (p < 0.05) providing effective pain relief in the perioperative period. Non-opioid analgesics promoted an optimal analgesic effect, did not cause residual sedation, anxiety, depressive effects and cognitive impairments, which showed their obvious advantage over opioids. Opioid-sparing effect was 96.3% (p < 0.05). Reducing the consumption of narcotic analgesics without worsening the quality of postoperative analgesia and the patient's well-being is an important advantage which allows minimizing the negative effects of opioids, facilitating the early rehabilitation of patients. Conclusions: Non-opioid analgesics can significantly limit endocrine and metabolic changes without worsening the quality of analgesia in the perioperative period.
