Clinical Study of Fospropofol Disodium for Injection in the Painless Endoscopic Diagnosis and Treatment

This is a study on the efficacy and safety of fospropofol disodium for injection in painless endoscopic diagnosis and treatment, project No.2024-YCRF-M1021, which will take more than 2 years to complete. This is a multicenter, randomized, double-blind, controlled clinical study. Using a computer-generated randomized number table, the patients were divided into two groups: the group L (fospropofol disodium group) and the group B (propofol group). After determining the group of enrolled patients, the drug was administered by two fixed anesthesiologists By participating in this study, it is possible to make your anesthesia induction stable, stable intraoperative circulation, awake and safe and comfortable, to reduce the incidence of intraoperative hypoxemia, intraoperative awareness, cardiovascular and cerebrovascular malignant events (malignant arrhythmia, cardiac arrest), which is conducive to your rapid postoperative recovery and reduce hospitalization costs.
