Legally speaking, the consent form of operation, anesthesia and power of attorney can only be signed by the patient himself, but in practice, the hospital often requires the patient himself and his close relatives to sign the consent form of operation and anesthesia. The main purpose of the hospital is to avoid the risks that may be brought by the operation, and to prevent the troubles and disputes that the unpredictable risks in the operation may bring to the hospital and medical staff.

The importance of surgical signature has the following aspects:

1, narcotic drugs are mostly highly toxic drugs, which are more toxic than general drugs. During anesthesia, unexpected things often happen, such as laryngeal spasm, respiratory obstruction, arrhythmia and even cardiac arrest, due to the special effects of drugs, physiological changes of patients and adverse stimulation of surgery.

2. Anesthesia accidents and complications are inconsistent with the size of the operation and the severity of the disease. Although some operations are small, serious anesthesia accidents will still occur. Therefore, the family members of patients should be fully prepared, not only to bear the risk of surgery, but also to bear the risk of anesthesia;

3. Surgery has certain trauma to human body and is a traumatic treatment. Before the operation, the consent of patients, family members and unit leaders must be obtained;

If you are a cancer patient, in order to save your life, you must do some "destructive" operations, such as amputation or removal of some important organs, which will make the patient permanently disabled or lose some physiological functions. All these situations require patients and their families to understand and make full preparations to ensure the smooth operation.
