Legal analysis: write agree or disagree, and sign. Pre-operative conversation signature is a summary to inform the patient of the condition, explain the operation method and make a preliminary prognosis evaluation. If the patient is undergoing non-general anesthesia surgery, such as local infiltration anesthesia, brachial plexus anesthesia, combined spinal-epidural anesthesia, the patient can sign by himself, because the patient's consciousness is clear during the whole operation, and he can fully communicate with the patient the risks of the operation and the expected results that may be achieved before signing. If the patient needs general anesthesia, the patient must be authorized to his immediate family members, and the operation can only be carried out with the signature of the immediate family members, because the patient is under general anesthesia and unconscious during the whole operation. Once there is a special accident during the operation, it is necessary to fully communicate with the patient's authorized family before deciding on the next treatment plan. It can be seen that the surgical signature can be signed by both patients and their families.

Legal basis: Article 72 of the Regulations on the Administration of Medical Institutions in People's Republic of China (PRC) stipulates that medical institutions must obtain the consent of patients and the consent and signature of their families or relevant personnel when performing surgery, special examination or special treatment; If the patient's opinion cannot be obtained, it shall be agreed and signed by the family members or relevant personnel; When patients' opinions cannot be obtained and no family members or related personnel are present, or other special circumstances are encountered, the attending physician will put forward a medical treatment plan, which will be implemented after being approved by the person in charge of the medical institution or the authorized person in charge. Therefore, it is well documented to ask the patient's family members to sign before operation, not the overlord clause of the hospital.
