Adult Participants Requiring Tracheal Intubation Under General Anesthesia for Elective Surgery
Conditions
Keywords
Anesthesia, Muscle relaxants
Brief summary
A multicenter, randomized, double - blind, placebo - controlled, parallel - group phase III clinical trial was carried out to evaluate the efficacy and safety of HRS - 9190 for skeletal muscle relaxation during tracheal intubation in the induction and maintenance phases of general anesthesia. The primary objective was to evaluate the effectiveness of HRS - 9190 in achieving skeletal muscle relaxation during tracheal intubation in the induction and maintenance phases of general anesthesia. The secondary objective was to assess the safety and pharmacokinetic profile of HRS - 9190.
Interventions
During the induction phase, 0.6 mg/kg of HRS-9190 was administered intravenously, and during the maintenance phase, 0.2 mg/kg of HRS-9190 was administered intravenously.
During the induction phase, 0.6 mg/kg of rocuronium was administered intravenously, and during the maintenance phase, 0.15 mg/kg of rocuronium was administered intravenously.

Study design
Masking description
Independent dispensing personnel were designated to conduct the trial, and both evaluators and participants remained blinded throughout. The trial drug was administered in accordance with the protocol. After blind verification, data were locked; the statistician then submitted an unblinding request. Specifically, the randomization and drug assignment codes were disclosed only to authorized statistical personnel to enable full analysis. Double-blinding was maintained unless broken for urgent clinical reasons-e.g. , serious adverse events or life-threatening emergencies-upon investigator decision, following immediate notification to the monitor, principal investigator, and sponsor. Unblinding authorization was pre-registered in the RTSM system. Once unblinded, the participant was classified as discontinued.
