: Ketamine offers effective pain relief with fewer side effects than traditional analgesics, making it a promising alternative for acute pain treatment. However, further research is needed to fully assess its role in perioperative care. This umbrella review aimed to compile the highest-quality evidence available regarding the application of ketamine in managing acute pain. : A thorough search of the literature was carried out in PubMed, Scopus, and the Cochrane Library, including systematic reviews that focused on the application of ketamine in managing acute pain. The data extraction included the research type, analgesics used, number of studies and patients per review, pain types, scoring methods, ketamine doses, administration routes, and reporting guidelines. : Of the 807 records identified, 20 studies met the inclusion criteria. In accordance with the AMSTAR-2 evaluation, most of the systematic reviews were rated as critically low quality. Intravenous ketamine administered during the perioperative period was found to reduce the pain intensity of acute pain within 15-30 and 60 min following treatment, and decrease postoperative opioid consumption by 14-50% at both 24 and 48 h after surgery. : Evidence shows that intravenous ketamine reduces the pain intensity, postoperative opioid use, and the risk of vomiting and nausea while improving analgesia, making it a valuable adjunct in perioperative pain management.
