Summary

Aortic valve stenosis is the most common debilitating valvular heart lesion in old patients. Transcatheter aortic valve replacement (TAVR) is an emergent technique for high-risk patients with aortic stenosis. In recent times, treatment has expanded to also include low- and intermediate-risk individuals. General anesthesia offers many advantages, mainly regarding the possibility of an early diagnosis and treatment of possible complications through the use of transesophageal echocardiography. Propofol is the most used sedative-hypnotic agent for the induction and maintenance of general anesthesia. However, adverse events such as hypotension, and bradycardia are associated with propofol sedation. Ciprofol is a novel anesthetic/sedative agent similar to propofol, with an equivalent efficacy ratio to propofol of 1/4 to 1/5. Ciprofol has properties of fast onset of action, rapid recovery, reduced injection pain and stable cardiorespiratory function, making it a promising alternative to propofol. The aim of this study is to explore the safety and efficacy of ciprofol when used for general anesthesia in patients undergoing transcatheter aortic valve replacement compared to propofol.

Interventions

DRUG

ciprofol

induction of anesthesia：group ciprofol received an IV injection of ciprofol at a dose of 0.2-0.4 mg/kg, and administration time of 30 s.When the eyelash reflex disappeared and the BIS value was ≤60 administration was stopped, followed by an IV injection of alfentanil 30 μg/kg and rocuronium 0.6 mg/kg. Maintenance of anesthesia: group ciprofol received an IV infusion of ciprofol 0.8-2.4 mg·kg-1·h-1.

DRUG

propofol

induction of anesthesia：group propofol received an IV injection of propofol at a dose of 1.0-2.0 mg/kg, and administration time of 30 s. When the eyelash reflex disappeared and the BIS value was ≤60 administration was stopped, followed by an IV injection of alfentanil 30 μg/kg and rocuronium 0.6 mg/kg. Maintenance of anesthesia:group propofol received an IV infusion of propofol 4-6 mg·kg-1·h-1.
