Clinical Trial Summary

To evaluate the efficacy and safety of ciprofol for the induction of general anesthesia in obese patients undergoing laparoscopic sleeve gastrectomy. A randomized, parallel, propofol injection positive control study will be conducted to select obese patients who will undergo laparoscopic sleeve gastrectomy in the author's hospital. To evaluate the efficacy and safety, the main observation index, secondary observation indexes, safety evaluation indexes, and the incidence of postoperative adverse reactions will be recorded and compared between the two groups.

Description:

To evaluate the efficacy and safety of ciprofol for the induction of general anesthesia in obese patients undergoing laparoscopic sleeve gastrectomy. A randomized, parallel, propofol injection positive control study will be conducted to select obese patients who will undergo laparoscopic sleeve gastrectomy in the author's hospital. To evaluate the efficacy and safety, the following indexes will be recorded and compared between the two groups.

• The main observation index：(1) The rate of successful anesthesia induction

• Secondary observation indexex：(1) Time from initial administration of study drug to loss of consciousness; (2) Time from initial administration of study drug to disappearance of eyelash reflex; (3) Changes in bispectral index(BIS) values during anesthesia induction

• Safety evaluation indexes：(1) Adverse events; (2) Intubation response rate; (3) Vital signs; (4) Evaluation of injection pain

• Adverse events to be focused on：(1)The incidence of blood pressure reduction requiring treatment during anesthesia induction; (2) The incidence of respiratory depression

Through study completion, an average of 1 year
Secondary	Time to LOC	Time from initial administration of study drug to loss of consciousness	During anesthesia induction, an average of 10 minutes
Secondary	Time to disappearance of eyelash reflex	Time from initial administration of study drug to disappearance of eyelash reflex	During anesthesia induction, an average of 10 minutes
Secondary	BIS	Changes in bispectral index(BIS) values during anesthesia induction	During anesthesia induction, an average of 10 minutes
