Efficacy and Safety of Ciprofol in Laparoscopic Sleeve Gastrectomy
- Registration Number
- NCT05522998
- Lead Sponsor
- The Third People's Hospital of Chengdu
- Brief 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.
- Detailed 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

- Primary Outcome Measures
Name Time Method The rate of successful anesthesia induction Through study completion, an average of 1 year The criteria for success are to meet the following two requirements at the same time: 1) successful induction (i.e. improved investigator awake / sedation score (MOAA / S) ≤ 1) after the administration of the study drug (at most 2 additional times are allowed); 2) No alternative anesthetics were used.
- Secondary Outcome Measures
Name Time Method Time to LOC During anesthesia induction, an average of 10 minutes Time from initial administration of study drug to loss of consciousness
Time to disappearance of eyelash reflex During anesthesia induction, an average of 10 minutes Time from initial administration of study drug to disappearance of eyelash reflex
BIS During anesthesia induction, an average of 10 minutes Changes in bispectral index(BIS) values during anesthesia induction
