Effect of ciprofol on induction and maintenance of general anesthesia in patients undergoing kidney transplantation.

OBJECTIVE: This study aims at evaluating the effects of ciprofol on the induction and maintenance of general anesthesia in patients undergoing kidney transplantation. PATIENTS AND METHODS: This prospective, randomized, single-blind study enrolled 120 patients aged 18-65 years who underwent general anesthesia for kidney transplantation. The patients were randomized into a ciprofol group (group C) and a propofol group (group P). Anesthesia induction: group C had injected IV with ciprofol 0.4 mg/kg, group P had injected IV with propofol 2.0 mg/kg, while both groups had injected IV with sufentanil 0.4-0.5 μg/kg and cisatracurium 0.2 mg/kg. Anesthesia maintenance: ciprofol was injected IV with 0.8-2.4 mg•kg-1•h-1 in group C, propofol was injected IV with 4-12 mg•kg-1•h-1 in group P, while remifentanil was injected IV with 8-15 μg•kg-1•h-1 and cisatracurium was injected IV with 0.1-0.2mg•kg-1•h-1, with the bispectral index (BIS) maintained at 40-60 during the operation. RESULTS: The success rate of sedation in both groups was 100%. Compared with the P group, in group C the time of disappearance of the eyelash reflex and a decline in the BIS to 60 was shorter (p<0.001); the time of awakening was prolonged (p<0.001); the number of sedative drugs administered was reduced (p<0.001); MAP fluctuated less five mins after transplantation (p<0.01); the incidence of injection pain during induction was reduced (p<0.001) and intraoperative hypotension was decreased(p<0.01). CONCLUSIONS: Ciprofol is safe and effective for anesthesia induction and maintenance in kidney transplantation and its sedative effect is better than that of propofol.
