A prospective randomised controlled study of patient‐controlled propofol sedation in phobic dental patients

The safety and effectiveness of patient‐controlled propofol sedation was prospectively assessed in 18 healthy, phobic dental patients. Using a randomised, crossover design each patient received two sessions of equivalent dental treatment under patient‐controlled or clinician‐controlled propofol seda...

description The safety and effectiveness of patient‐controlled propofol sedation was prospectively assessed in 18 healthy, phobic dental patients. Using a randomised, crossover design each patient received two sessions of equivalent dental treatment under patient‐controlled or clinician‐controlled propofol sedation. The patient‐controlled technique used 29.8% less drug (time‐weighted dose) than the clinician‐controlled method (p = 0.011). There was a high correlation between number of demands and number of doses actually infused during the patient‐controlled technique (r = 0.99, p
