Remimazolam and Esketamine for CT-Guided Aortic Graft Infection Drainage in a Patient with Severe Systematic Comorbidities: A Case Report

Background/Objectives: The management of patients with severe systemic comorbidities undergoing radiologic interventional procedures presents a significant challenge for anesthesiologists. Selecting an appropriate combination of anesthetic drugs is crucial to ensure a safe, painless procedure, facilitate rapid recovery, and minimalize complications. Here, we present a case of a 68-year-old female patient of ASA V status with a history of diabetes, coronary artery disease, and severe chronic obstructive pulmonary disease due to lung emphysema and dependence on a home oxygenator, requiring sedation for CT-guided percutaneous drainage of the aortic graft infection. Methods: After on-site emergent patient preparation and several position adjustments, sedation was initiated and maintained using continuous infusions of remimazolam and esketamine. Results: Throughout the procedure, the patient remained sedated, comfortable, and free of unwanted movements. The patient was hemodynamically stable and maintained oxygen saturation between 92 and 96%. Conclusions: In our opinion, the combination of remimazolam and esketamine demonstrated an effective and safe profile for procedural sedation. This approach holds the potential to influence standard operating protocols, particularly for patients with severe and multiple comorbidities requiring personalized anesthetic management.
