Optimising anesthesia support during operations on the abdominal aorta and its branches

Abstract

Background: Pathology of the aorta includes aortic aneurysms, coarctation, dissection, atherosclerotic disease, and aortitis. The only two evidence-based treatment options for abdominal aortic repair are endovascular and open surgery. The anesthetic approach and medications may impact the outcomes of the surgical repair of the abdominal aorta and its branches. Aim: to evaluate the use of various analgesic regimens and local, regional, or general anesthesia in "optimising" surgical outcomes in patients undergoing surgical repair of the abdominal aorta and its branches. Methods: In this review, English studies from common databases such as Pubmed/MEDLINE, Google Scholar, Web of Science, Scopus, and the Cochrane Library with the keywords "Abdominal aorta," "operations," "aortic branches," combined with keywords, involving " anesthesia were involved." The end date for this review was November 2022. Scientific novelty: Recent scientific studies have focused on the use of advanced monitoring technologies such as cerebral oximetry and microdialysis to improve the safety and efficacy of anesthesia management in aortic surgery. These technologies provide more accurate and real-time information about cerebral perfusion and metabolism, allowing the anesthesiologist to identify and manage potential complications such as cerebral ischemia more effectively. Additionally, the use of pharmacological agents such as dexmedetomidine and remifentanil has been shown to reduce the risk of postoperative delirium and cognitive dysfunction, further improving patient outcomes. Conclusion: Aortic surgery is a complex and high-risk procedure that requires careful management of anesthesia to ensure patient safety and optimal outcomes. With ongoing advances in anesthesia techniques and monitoring technologies, there is reason to be optimistic about the future of aortic surgery and the prospects for improved patient outcomes. The anesthesiologist plays a critical role in this process, working closely with the surgical team to provide safe and effective anesthesia throughout the procedure and ensuring that the patient receives appropriate pain management and other supportive care in the postoperative period
