Dental Sedation for Patients with Intellectual Disability：A Prospective Study of Manual Control versus Bispectral Index-Guided Target-Controlled Infusion of Propofol

Abstract Study Objective To investigate the use of propofol sedation using Bispectral Index (BIS)-guided target-controlled infusion (TCI) in dental patients with intellectual disability. Design Single-center, prospective, randomized clinical trial. Setting Academic outpatient clinic. Subjects 40 ASA physical status 1 and 2 patients with intellectual disability. Interventions Patients were randomized to two groups. The manual control (MC) group (n = 20) had sedation by manually controlled infusion of propofol without a BIS index monitor. The BIS-TCI group (n = 20) had sedation by BIS-guided TCI of propofol. Measurements The required dose of propofol, recovery time for the eyelash reflex, and spontaneous eye opening times were recorded. Main Results BIS-TCI significantly reduced the dose of propofol and shortened the recovery times for eyelash reflex and spontaneous eye opening. Conclusion Propofol sedation using BIS-guided TCI is a useful and safe method in the management of patients with intellectual disability.
