GLP-1 Receptor Agonists: Beyond Diabetes-What the Neurosurgeon Needs to Know.

Background And Objectives: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have gained increasing popularity since the approval of semaglutide by the United States Food and Drug Administration for chronic weight management. Significant benefits have been noted in glycemic control and cardiovascular health. However, as increasing numbers of patients are started on these medications, it is important for neurosurgeons to have knowledge of any perioperative considerations and side effects related to this class of drugs.

Methods: We performed a qualitative literature review using the PubMed and Embase databases, using the following key words: GLP-1 RAs adverse events; GLP-1 RAs and anesthesia; substance use disorders; and addiction, functional neurosurgery, nervous system rehabilitation, and spinal cord injury. Articles of relevance to perioperative management of these medications and specific benefits in the neurosurgical field were discussed.

Results: Recent guidance from the American Society of Anesthesiologists demonstrates the importance of tailored management of GLP-RA drugs for surgical patients. In addition, certain positive effects have been noted with relation to substance use disorders, neural protection and rehabilitation, and neurodegenerative disorders such as Alzheimer's disease.

Conclusion: In this article, we review what the neurosurgeon needs to know about the perioperative management of GLP-1 RAs and discuss existing literature in clinical and preclinical studies for potential indications and benefits of these medications, which can influence the management of conditions treated by neurosurgeons.
