Anesthesia for Minimally Invasive Coronary Artery Bypass Surgery

Abstract

Minimally invasive coronary artery bypass grafting (MI-CABG) has emerged as a transformative approach to coronary revascularization, offering reduced morbidity, faster recovery and improved cosmesis compared to conventional coronary artery bypass grafting (CABG). Performed without full sternotomy and commonly without cardiopulmonary bypass (CPB), MI-CABG encompasses a variety of techniques. These procedures present unique challenges for the anesthesiologist, necessitating a tailored perioperative strategy. This review explores the anesthetic management of MI-CABG, focusing on preoperative assessment, intraoperative techniques, and postoperative care. Preoperative evaluation emphasizes cardiac, respiratory, and vascular considerations, including suitability for one-lung ventilation (OLV) and the impact of comorbidities. Intraoperatively, anesthesiologists must manage hemodynamic instability, ensure effective OLV, and maintain normothermia. Postoperative strategies prioritize multimodal analgesia, early extubation, and rapid mobilization to leverage the benefits of a minimally invasive approach. By integrating surgical and anesthetic perspectives, this review underscores the anesthesiologist’s pivotal role in navigating the physiological demands of MI-CABG. As techniques evolve and experience grows, a comprehensive understanding of these principles will enhance the safety and efficacy of MI-CABG, making it a viable option for an expanding patient population.
