Anesthesia includes local anesthesia and general anesthesia, and general anesthesia includes inhalation anesthesia and intravenous anesthesia. The metabolism of anesthetic drugs in the body mostly relies on the patient’s liver metabolism and kidney excretion. Anesthetic drugs in regular doses will not damage the patient’s kidney function, but during anesthesia, if the patient loses a lot of blood or has long-term hypotension, resulting in reduced kidney perfusion and blood flow, it will affect the patient’s kidney function for a long time, resulting in reduced urine output. In the clinical manifestation of hypotension and decreased urine volume, the anesthesiologist will monitor the patient comprehensively during the operation, which includes blood pressure and urine volume, and if these clinical manifestations occur in the patient during the monitoring process, the anesthesiologist will immediately deal with them, so the anesthesia will not damage the patient’s kidney function.
