Abstract

To manage pain in the emergency room, this review sought to evaluate the effectiveness of intravenous lidocaine with conventional analgesics. The PubMed, Embase, and ScienceDirect electronic databases were searched between the years 2019 and 2024, and randomized controlled studies that contrasted IV lidocaine with a control group of conventional analgesics were included. It was found that in the treatment of biliary colic, intravenous lidocaine can be a helpful option since it can lessen pain faster than morphine sulfate without causing serious side effects. When given intravenously to emergency department patients with suspected renal colic, the combination of lidocaine and ketorolac produces greater analgesia than lidocaine alone, but it offers no analgesic benefits over ketorolac alone. For both general abdominal discomfort and a subgroup of patients with nephrolithiasis, intravenous hydromorphone was better than intravenous lidocaine.
