In recent years, many clinical studies have also confirmed the sedative effect of ciprofol. However, more clinical research is still needed on its clinical application characteristics in special populations.Objective: The aim of this study was to compare the clinical effects of ciprofol and propofol in general anesthesia induction of elderly patients.Methods: 60 elderly (aged ≥ 75 years) patients underwent hip fracture surgery were randomly into two groups of a 1:1 ratio. Group C (ciprofol group): 0.3mg/kg ciprofol was infused. Group P (propofol group): 1.5mg/kg propofol was infused. The observation period was from the infusion of test drug to 5 min after endotracheal intubation. The primary outcomes included the incidence of severe hypotension and hypotension during the observation period. The secondary outcomes were as follows: the success rate of general anesthesia induction, the number of additional sedation, the time of loss of consciousness (LOC), Δ MAP, Δ HR, adverse events and the frequency of vasoactive drugs used.Results: Finally, 60 subjects completed the study. Compared with Group P, the incidence of severe hypotension in Group C was lower (26.7% vs 53.3%, P = 0.035), the incidence of hypotension was also lower (36.7% vs 63.3%, P = 0.037), Δ MAP in Group C was significantly lower (31.4 ± 11.4 vs 39.6 ± 15.7, P = 0.025), the frequency of ephedrine used and the incidence of injection pain in Group C were also significantly lower.Conclusion: Ciprofol showed similar efficacy to propofol when used for general anesthesia induction in elderly patients underwent hip fracture surgery and could maintain more stable blood pressure.Keywords: Ciprofol, elderly, Hip fracture surgery, general anesthesia, hypotension
