First, is the psychological expectation of the candidate itself too high, for the successful completion of the surgery results are not satisfied with what to do? The doctor has the responsibility and obligation to explain clearly the procedure and details of the surgery, and inform the candidate of the post-operative recovery and individual differences, and if the candidate shows that the post-operative effect does not reach the range that the doctor’s level of technology can achieve, the doctor can consider not performing the surgery for the candidate, and if the candidate does not make excessive demands, the doctor can also achieve the candidate’s requirements. If the doctor does not communicate with the patient in detail and does not have a good understanding of the patient’s requirements and psychology, the surgery will increase the risk by 30%. For a successful surgery, if the patient is not satisfied with the result of the surgery, the doctor can communicate with the patient again to see which aspect of the surgery the patient is not satisfied with, if the patient is not satisfied with the scope of the surgery, psychological guidance can be given. If the patient is not satisfied with the possible complications and some problems within the scope of surgery, the doctor can make appropriate corrective or repair measures according to the situation so as not to cause surgical failure. Secondly, the surgery itself has risks, and once the surgery fails, how to face and defend the rights. Answer: After detailed communication between the doctor and the candidate before surgery, the doctor and the candidate must reach a consensus, and a consent form for surgery must be signed before surgery, the surgery itself has risks, and the candidate should do accept and be able to bear the risks, if the medical risks occurring in the medical unit and the surgeon is responsible, such as the possible complications of surgery and the risks, the patient also needs to consider carefully accepting the risks and agreeing before surgery. There are two reasons for surgical failure: first, the patient has complications, which are inevitable in surgery, once the complications occur doctors will take remedial measures to minimize the risk; second, surgical accidents, there are many kinds of surgical accidents, there are anesthesia accidents, unpredictable accidents arising from the surgical process, etc., if there are accidents need to be rescued by doctors in a timely manner to avoid the risk, such as the risks that can not be avoided should be carried out with the family for detailed Explanation of communication, once the patient can not accept the failure of surgery, the first need for detailed explanation of surgery by the doctor, the reasons for its operation and the resulting complications record account to the medical institution, the medical institution for identification, medical civil disputes and other civil disputes, belong to the property relations and personal relations between equal subjects, belongs to the adjustment of the civil law. According to the principle of “private law autonomy”, the state usually does not intervene, therefore, the parties can negotiate on medical disputes, and can also conduct civil and administrative mediation, in theory, medical contract disputes can also be resolved by arbitration, but at present, arbitration to resolve medical disputes has not been taken seriously. State intervention in civil medical disputes is manifested in civil litigation, which requires parties to sue in order to defend their rights.
