Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The 95% Effective Doses (ED95) of Propofol and Fospropofol Disodium;The incidence of hypotension during general anesthesia induction (defined as drug-induced mean arterial pressure [MAP] < 65 mmHg); | — |
Secondary
| Measure | Time frame |
|---|---|
| Induction success rate (defined as a Modified Observer's Assessment of Alertness/Sedation (MOAA/S) score = 1 within 5 minutes after the start of intravenous administration of propofol or fospropofol disodium);The time from the first administration of fospropofol disodium to the disappearance of the eyelash reflex;The time interval from the completion of fospropofol disodium administration to the initiation of anesthetic maintenance drugs;Observe and record the heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), SpO?, and Narcotrend (NT) values of patients in both groups at each time point: before anesthesia induction (T0), immediately after anesthesia induction (T1), 5 minutes after anesthesia induction (T2), 10 minutes after anesthesia induction (T3), 15 minutes after anesthesia induction (T4), and at the time of surgical incision (T5); calculate the blood pressure varia;The usage of vasoactive drugs during anesthesia induction ;The incidence of intraoperative awareness;Adverse reaction profile: paresthesia, injection pain, bradycardia (HR < 45 bpm), and prolongation of the Q-T interval.; | — |
