Conclusion
The efficacy and safety of a single i.v. bolus dose of 0.5 mg/kg ciprofol for the induction of general anesthesia in patients undergoing selective surgery was comparable to propofol administered at a dose of 2.0 mg/kg. Lower doses of ciprofol, 0.3 mg/kg or 0.4 mg/kg, could also achieve the same efficacy but occasionally an additional top-up dose was required.
