Ciprofol's Influence on LVOT VTI in Elderly Painless Colonoscopy Patients

Cirpropofol is a 2,6-disubstituted phenol derivative that introduces a cyclopropyl group based on the chemical structure of propofol, increasing its affinity with GABA receptors and stereoeffect, thus its effect is 4-5 times that of propofol. Studies have found that the incidence of hypotension, injection pain, and respiratory depression during cirpropofol anesthesia is lower than that of propofol.

Propofol has favorable pharmacokinetic properties with minimal residue. Currently, it is widely used for endoscopic procedure sedation, but there are still many limitations, such as a narrow therapeutic window, injection pain, hypotension, and respiratory depression.
