Анализ эффективности интраоперационной локальной инфильтрационной аналгезии при эндопротезировании коленного сустава

Abstract

The problem of postoperative pain after knee replacement is a significant problem that worsens the condition of patients and impedes the activation and rehabilitation of patients. To prevent the development of severe pain after knee replacement, local infiltration analgesia has been proposed, including an anesthetic drug, a non-steroidal anti-inflammatory drug and adrenaline.Purpose of the study: to evaluate the effectiveness of local infiltration analgesia in knee replacement with assessment of postoperative pain.Methods. A single-center retrospective study examined the outcomes of 81 patients with knee osteoarthritis who were scheduled for primary knee replacement between January 2022 and December 2023. Patients in the main group (40 people) were administered a single dose of local infiltration analgesia intraoperatively, while patients in the control group (41 people) did not. The results were compared in terms of postoperative pain and narcotic analgesic consumption in both groups.Results. Patients in the study group had significantly lower pain scores from the first postoperative day (VAS was 3.05) to the fourth postoperative day (2.75) compared with the control group (5.06 and 3.2) (p<0.001) . The consumption of narcotic analgesics in the main group was also much lower compared to the control group.Conclusions. The use of local infiltration analgesia during surgery can effectively reduce postoperative pain and the need for narcotic analgesics in patients with knee replacement.Key words: endoprosthetics, infiltration analgesia, knee joint, postoperative pain.
