The invention relates to a method and system for predicting post-induced hypotension of a patient, and belongs to the technical field of hypotension prediction.The method comprises the steps that original data reflecting the cardiovascular autonomic nerve regulation capacity of the patient is obtained; preprocessing the original data to obtain target data, and calculating a target pressure reflex sensitivity BRS and a target pressure reflex effective index BEI based on the target data and the same-direction change sequence of the continuous heartbeat; inputting the target pressure reflex sensitivity BRS, the target pressure reflex effective index BEI and the patient baseline data into a Logistic regression model to obtain a hypotension risk probability; and determining a hypotension risk level of the patient based on the hypotension risk probability and a preset threshold range. According to the method, the target pressure reflex sensitivity BRS and the target pressure reflex effective index BEI serve as predictive factors, so that the probability of predicting hypotension of a patient can be improved before the patient receives anesthesia induction.

This invention discloses an endothelin A receptor antagonist-albumin fusion protein and its application in preventing and treating hypotension during anesthesia induction. The fusion protein is formed by chemically coupling BQ-123 with human serum albumin (HSA). BQFu significantly enhances its antihypertensive effect by prolonging the half-life of BQ-123 and improving plasma stability. Experiments show that BQFu dose-dependently inhibits the decrease in mean arterial pressure (MAP) in a propofol-induced hypotension model, with a sustained and stable effect in the high-dose group (30 mpk), shortening the recovery time to 20.8 ± 10.5 min, while maintaining BQ-123 activity. This invention provides a long-acting and safe prevention and treatment strategy for hypotension during anesthesia induction.
