Brief Summary

Preliminary studies have illuminated the promising nature of ciprofol, indicating its enhanced safety spectrum, superior potency, and a diminished likelihood of experiencing injection-related discomfort. Venturing deeper, this research embarked on an ambitious quest to measure the 95% effective volume of ciprofol for induction of general anesthesia by a modified sequential method and juxtapose the 95% effective volume dosage of ciprofol against a corresponding dose of remimazolam during the initiation of general anesthesia. The study delved into diverse anesthetic protocols, meticulously scrutinizing the safety and efficacy credentials of ciprofol. The ultimate vision was to pave a robust foundation for the sophisticated and judicious utilization of ciprofol in clinical landscapes.

Study Arms (2)

Group C

EXPERIMENTAL

Ciprofol + sufentanil + rocuronium bromide

Drug: Ciprofol

Group R

ACTIVE COMPARATOR

Remimazolam+ sufentanil + rocuronium bromide

Drug: Remimazolam

Interventions

For induction of anesthesia, an experimental dose of ciprofol was given, and when the patient lost consciousness and the Modified Observer's Alertness/Sedation scale(MOAA/S score) was less than 1, then intravenous sufentanil and rocuronium bromide were administered, and tracheal intubation was performed 3 minutes later

Also known as: Ciprofol injection
Group C

For induction of anesthesia, an experimental dose of remimazolam was given, and when the patient lost consciousness and the Modified Observer's Alertness/Sedation scale(MOAA/S score) was less than 1, then intravenous sufentanil and rocuronium bromide were administered, and tracheal intubation was performed 3 minutes later

Also known as: Remimazolam Tosylate for Injection
Group R
