## Contribution

The paper provides a comprehensive review of innovations and challenges in acute care surgery, emphasizing the need for global equity and technological adoption.

## Key findings

- Artificial intelligence is being used to predict sepsis and assess surgical risks.
- Global disparities in acute care surgery are significant, with underdeveloped systems in low-resource regions.
- ERAS protocols and telemedicine are key innovations improving patient outcomes.

## Abstract

Acute care surgery (ACS) is an integrated specialty encompassing trauma, emergency general surgery, and surgical critical care, aimed at delivering comprehensive, timely management of surgical emergencies. This narrative review examines the evolution of ACS from a procedure-focused model to a comprehensive perioperative care specialty. It analyzes significant innovations, including the use of artificial intelligence (AI) for sepsis prediction and complication risk stratification, the emerging role of robotic surgery, the incorporation of telemedicine, and the implementation of Enhanced Recovery After Surgery (ERAS) protocols. The review also identifies critical systemic challenges, including surgeon burnout, ethical dilemmas in end-of-life care, and chronic underfunding. Furthermore, it highlights substantial global disparities in the implementation of ACS models, with well-established systems in North America and fragmented or absent services in low-resource settings. This synthesis concludes that the future of ACS hinges on adopting technological advancements, addressing workforce sustainability, and developing policies to ensure equitable, high-quality emergency surgical care worldwide.
