This randomized, single-blind, crossover study compares remimazolam and propofol for monitored anesthetic care during fractional ablative CO₂ 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).
Patients will be randomized to receive either remimazolam or propofol during their first laser session, and the alternate drug during their second session 4-6 weeks later. Outcomes include respiratory depression, sedation onset and recovery times, hemodynamic changes, and patient satisfaction.
Inclusion Criteria: * Age ≥ 18 years * Undergoing both outpatient Session #1 and Session #2 of fractional ablative CO2 laser therapy Exclusion Criteria: * History of previous fractional ablative laser therapy for burn scar * Procedure expected to last longer than 30 minutes * Allergy such as dextran 40 or contraindication to either of the study drugs * Pregnant and/or breastfeeding * Subjects who are unable to or choose not to give informed consent
