ERAS-Based Anesthetic Management of Patients Undergoing Abdominal-Based Free Flap Breast Reconstruction: A Narrative Review

Microsurgical breast reconstruction after mastectomy is emerging as the standard of care for patients with breast cancer. The enhanced recovery after surgery (ERAS) pathway in abdominal-based free flap breast reconstruction is in its early stage of development and lacks established consensus or guidelines. In the multidisciplinary ERAS team, the anesthesia sub-team is responsible for the provision of several core elements in the ERAS pathway including anesthetic protocol optimization, perioperative fluid management and homeostasis regulation, normothermia maintenance, perioperative analgesia, and postoperative nausea and vomiting prophylaxis. Here, we summarized the state-of-the-art in anesthetic practice for the patients undergoing abdominal-based free flap breast reconstruction within an ERAS framework, and also introduced the perioperative strategy for this surgical population based on the ERAS pathway in our center, aiming to improve free flap outcome and patient satisfaction, and accelerating their recovery following surgery.
