Abstract:In recent years, the concept of enhanced recovery after surgery (ERAS) has been put forward and popularized based on the invention of new anesthesia and analgesic techniques, the development of minimally invasive surgery, and the discovery of drugs to reduce surgical stress response, which has become a new trend in the international medical field. The concept of ERAS penetrates the entire perioperative period by a series of optimization measures. ERAS regards patients as the core on the basis of the evidencebased medicine and multidisciplinary cooperation. Its core idea philosophy is to promote patients postoperative rehabilitation for reducing the side effects of surgical stress on the psychological and physiological of patients and decreasing the postoperative complications to shorten the postoperative hospitalization. ERAS reduces hospitalization costs, and improves medical experience, lessens hospital costs, accumulates medical experience and allocates the limited medical resources rationally. The anatomical position of head and neck tumor is special, and the surgical trauma is large, and the surgical method is complex. Therefore, patients often recover slowly after surgery. The incidence of the surgical complications is high, so the concept of ERAS is helpful to promote the optimization of the optimization of the current diagnosis and treatment mode.
