Clinical Trial Summary

This is a multicenter, randomized, double-blind, etomidate-controlled phase III clinical trial. The primary objective is to compare the efficacy and safety between ET-26 and etomidate in the induction of general anesthesia in subjects undergoing elective surgery, so as to provide a reference for the marketing registration of methoetomidate hydrochloride for injection.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Success rate of anesthesia induction	modified observer's assessment of alert=1 (only one additional dose was allowed) and endotracheal intubation was completed within 7 minutes from the beginning of study drug infusion, and no remedial drugs were used	within 7minutes after injection
Secondary	Time to loss of consciousness		Time from first administration of study drug to MOAA/S(modified observer's assessment of alert)=1,every 1 minute ±5 seconds, within 3 minutes after injection
Secondary	The percentage of time between 40=BIS(Bispectral index)=60		During the period from the initial administration to the successful intubation of the tracheal tube,every 1 minute±20 seconds, within 7minutes after injection
Secondary	The percentage of subjects with eyelash reflexes disappearing		within 3 minutes after injection
Secondary	time required to achieve eyelash reflex disappearance		within 3 minutes after injection
Secondary	the use of investigational drugs and remedial drugs		Induction period of anesthesia,within 7minutes after injection
Secondary	Proportion of subjects using remedial sedatives		Induction period of anesthesia,within 7minutes after injection
Secondary	The time to successfully intubate		within 7minutes after injection
Secondary	intubation reaction	Whether coughing, body movement reaction	within 5 minutes after successful intubation
Secondary	Changes of BIS(Bispectral index) within 30 minutes after endotracheal intubation successfully (such as the time percentage between BIS 40 and BIS 60)		30 minutes after successful intubation
Secondary	Anesthesiologists' satisfaction scores on the transition between induction and maintenance of anesthesia.	The anesthesiologist's satisfaction score for the connection between induction of anesthesia and maintenance of anesthesia, on a scale of 10, 0 being very dissatisfied and 10 being very satisfied.	immediately after surgery
