Intraoperative hypotension during general anesthesia after metamizole administration: a case report and literature review
Intraoperative hypotension during general anesthesia after metamizole administration: a case report and literature review

Summary/Abstract: Background: Multiple factors often cause hypotension in patients undergoing operations. The simultaneous presence of several detrimental factors tends to lower arterial pressure. Aim of the study: To investigate the specificity of intraoperative hypotension during general anesthesia after metamizole administration and describe this phenomenon based on a literature review. Case report: This report describes a patient who experienced a sudden drop in blood pressure after receiving metamizole, an agent commonly used for intraoperative pain management during general anesthesia. However, the drop in blood pressure was not accompanied by other symptoms, indicating that it was unlikely caused by additional factors. The patient was treated with a sympathomimetic agent. Conclusions: Metamizole is a relatively safe drug commonly used for optimal pain control in anesthesia practice. The occurrence of hypotension after its administration is an infrequent phenomenon, but proper monitoring and observation of patients’ vital signs during infusions of this drug are essential.
