Abstract
12046 Background: Perioperative pain (POP) in high-risk geriatric patients with cancer (HRGCP) is an important issue. The purpose of this study was to optimize perioperative analgesia in HRGCP. Methods: This randomized study of the quality and effectiveness of perioperative analgesics included 115 HRGCP aged 64-88 years who underwent surgeries on the organs of the chest, abdomen and pelvis for various cancers. The patients were divided into 2 groups. Group 1 (n = 52): patient-controlled analgesia with morphine and nonsteroidal anti-inflammatory drugs (NSAIDs); group 2 (n = 63): ultrasound-guided bilateral transversus abdominis plane (TAP) block with ropivacaine. Intraoperative and perioperative analgesia was maintained with a continuous infusion of lidocaine, magnesium sulphate, microdoses of fentanyl and NSAIDs. Results and pain syndrome were assessed by monitoring the Efficacy Safety Score (ESS), personal and reactive anxiety, stress response (cortisol, insulin, lactate, glucose), rates of functional activity recovery, the need for opioid analgesics, frequency of postoperative nausea and vomiting (PONV). Results: Patients in group 2 showed a significant decrease in the perioperative need for opioid analgesics and significantly decreased POP. Analysis of variance of mean values revealed statistically lower scores of ESS, visual analogue scale and POP (p < 0.05) during the first 24 hours of perioperative period in group 2 compared with group 1. Patient-controlled analgesia showed analgesic effect in 88.5% (p < 0.05) cases. However, the effect was less pronounced, compared to multimodal analgesia, and did not reduce cognitive disorders. In group 2, opioid-sparing analgesic effect was 95.3% (p < 0.05). Multimodal analgesia reduced the stress response (p < 0.05) in perioperative period and did not cause cognitive dysfunction while reducing PONV episodes, unlike morphine. Despite the minimal doses of narcotic analgesics in group 2, multimodal analgesia provided safe analgesia and functional activity recovery in perioperative period with minimum negative effects of opioids. Conclusions: The strategy of multimodal analgesia based on a combination of intraoperative TAP block and infusions of lidocaine and microdoses of fentanyl can significantly improve the quality of analgesia in perioperative period.
