Effect of different doses of ciprofol on hemodynamics induced by general anesthesia in elderly diabetic patients undergoing spinal surgery: a double-blind, randomized, controlled study.

Background: To evaluate the safety and efficacy of different doses of ciprofol for the induction of general anesthesia in elderly patients with diabetes undergoing spinal surgery.

Methods: Ninety elderly diabetic patients scheduled for elective single-level posterior lumbar interbody fusion (PLIF) under general anesthesia were enrolled and randomly assigned to three groups according to the induction dose of ciprofol: group A (0.2 mg/kg), Group B (0.3 mg/kg), and Group C (0.4 mg/kg). The safety and efficacy of anesthesia induction were compared among the three groups.

Case Presentation: The incidence of hypotension in Group C (46.4%) was significantly higher than that in Groups A (7.4%) and B (14.8%) (P < 0.05). The area under the time-mean arterial pressure curve (AUT) was significantly greater in Group C (176.39 ± 33.83 mmHg·min) than in Group B (158.44 ± 26.55 mmHg·min) and Group A (143.59 ± 19.52 mmHg·min) (P < 0.05). The incidence of intubation response was highest in Group A (77.8%, P < 0.05). Significant differences in bispectral index (BIS) values were observed at 3, 4, and 5 min post-administration among the groups CONCLUSIONS: The induction regimen of 0.3 mg/kg ciprofol combined with 0.4 µg/kg sufentanil and 0.7 mg/kg rocuronium provided superior hemodynamic stability and reduced the need for vasoactive drugs in elderly diabetic patients. This regimen was found to be more favorable compared to the 0.2 mg/kg and 0.4 mg/kg ciprofol dosing groups, demonstrating an optimal balance of safety and efficacy during anesthesia induction in this high-risk population. This trial was registered in the Chinese Clinical Trial Registry on February 26, 2024 (Registration Number: ChiCTR2400081164).
