Right blood level of ciprofol for anesthesia during thyroid surgery
Median Effective Concentration of Ciprofol and Its Correlation With Bispectral Index: A Prospective Observational Study
This test looks at ciprofol blood levels to see what keeps adults aged 18–65 safely unconscious during elective thyroidectomy.

What this trial studies
This single-center observational study enrolls adults scheduled for elective thyroidectomy who meet ASA I–II criteria. General anesthesia is induced with ciprofol for all participants while consciousness levels are measured using standardized scales during induction. Investigators record ciprofol blood concentrations and follow patients after surgery to track pain and cognitive recovery. The goal is to relate blood levels to clinical depth of anesthesia and short-term postoperative outcomes.
Who should consider this trial
Good fit: Adults aged 18–65 with ASA physical status I–II who are scheduled for elective thyroidectomy and can give written informed consent are the intended participants.
Not a fit: Patients with severe liver or kidney failure, significant cardiovascular disease, extreme BMI, recent sedative/opioid use, known hypersensitivity to propofol/ciprofol, or major neuropsychiatric disorders are unlikely to benefit or be eligible.
Why it matters
Potential benefit: If successful, the findings could help clinicians choose safer, more effective ciprofol dosing for thyroid surgery, potentially speeding recovery and reducing side effects.
How similar studies have performed: Previous clinical work with ciprofol for general anesthesia has shown promising sedation comparable to propofol, but precise target blood concentrations for thyroidectomy remain limited.
