Abstract: In clinical practice, informed consent to anesthesia technology is still a unique field of anesthesiology. For patients with mental disorders, anesthesiologists' neglect of the process of informed consent has become a weak link in clinical work. With the primitive moral instinct of humans and based on sympathetic moral care for patients with mental disorders, proxy consent is considered to be beneficial to patients, but in reality, there are many factors that restrict their rights in anesthesia informed consent. In the medical model of doctor-patient joint decision-making, patients with mild mental disorders should be involved in the informed consent process as much as possible, and the depth and breadth of the information provided depend on the patient's insight. The path to truly obtaining informed consent for anesthesia from patients with mental disorders needs to be optimized. Through multi-disciplinary cooperation and other methods, we can achieve real informed consent and protect the rights of patients with mental disorders.
