This randomized, single-blind, crossover study compares remimazolam and propofol for monitored anesthetic care during fractional ablative CO laser therapy for burn scars. The primary aim is to assess incidence of respiratory depression, defined as a need for advanced airway maneuvers (jaw thrust/chin lift, insertion of oral or nasal airway, or bag mask ventilation), and hypopnea (respiratory rate \< 8).
