Abstract

Background: Sedation plays a crucial role in the care of intensive care unit (ICU) patients, addressing the challenges presented by factors such as agitation, anxiety, and delirium, particularly during mechanical ventilation (MV). Dexmedetomidine and propofol are commonly used sedatives, each with its unique characteristics and side effects. Combining these agents has been proposed to optimize effectiveness and minimize adverse effects. This study aims to compare the efficacy of the dexmedetomidine-propofol combination with dexmedetomidine alone and propofol alone for sedation during mechanical ventilation in ICU patients. Methods: A triple-blinded clinical trial was conducted in Isfahan, Iran, involving patients eligible for spinal fusion surgery and mechanical ventilation. Patients were randomized into three groups: dexmedetomidine alone (DO), propofol alone (PO), and a combination of both drugs (DP) dexmedetomidine-propofol (ProDex). Various dosages and infusion protocols were carefully administered, and patients were assessed for demographic and clinical variables. Hemodynamic parameters and sedation levels were monitored, and statistical analysis was performed. Results: The study involved 87 patients, with the ProDex group demonstrating the shortest mechanical ventilation duration. Hemodynamic stability was observed in the ProDex group, with significantly lower systolic blood pressure and heart rate compared to other groups. Sedation scores did not differ significantly among groups, suggesting similar sedative effects. The ProDex group exhibited favorable outcomes despite differences in hemodynamic variables. Conclusion: The dexmedetomidine-propofol combination appears effective in minimizing side effects associated with monotherapy sedation, leading to favorable clinical outcomes. This study contributes valuable insights into optimizing sedation strategies for mechanically ventilated ICU patients. © 2024 Tehran University of Medical Sciences.
