The Establishment, Evolution, and Current Status of the Chang Gung Microsurgical Intensive Unit

Abstract For over four decades, Chang Gung Memorial Hospital has maintained a dedicated microsurgical intensive care unit (MICU). This article explicates the role of this specialized unit within this high-volume center characterized by significant surgical complexity, examines its necessity, and offers insights for international colleagues. Established in the early 1980s during Taiwan's rapid industrialization to address severe limb trauma in a young workforce, the unit has evolved to support an increasing volume of complex head and neck, breast, lymphedema, and peripheral nerve reconstruction. Although global trends favor ward-based care, the MICU remains essential within our hospital context to ensure optimal patient care that individual surgical specialties strive for. Alongside clinical outcomes, the unit also aims to reduce the surgeons' postoperative burden, thereby enhancing surgical efficacy and laying the foundation for continued academic pursuit through centralized, comprehensive data collection for all microsurgical cases of the center. We present this model not as a universal advocacy, but as a reference for medical centers in regions with healthcare systems similar to Taiwan, especially those with comparable microsurgical volumes, varieties, and levels of complexity.
