What kind of person can't get a general anesthetic

Although it is true that the effect of general anesthesia, reliable, but sometimes can happen respiratory system, circulatory system and central nervous system complications, such as choking, airway obstruction, pneumonia and atelectasis, low blood pressure, etc., and general anesthesia patients with loss of consciousness, the patient is difficult to cooperate with performer, when hit a nerve root intra-spinal canal operation etc, Patients can not respond immediately and there is a possibility of injury to the nerve, spinal cord.

During local anesthesia, the patient can stay awake. For example, when the nerve and spinal cord are touched during the operation, the patient can respond immediately and keep close cooperation with the surgeon to avoid intraoperative nerve injury. Local anesthesia is a popular and safe anesthesia method with slight interference to the function of the whole body's important organs, few complications, simple operation and low cost, but the analgesia is not perfect and the effect is not satisfactory. Anterior surgery due to can't look straight into the real phenomenon of conditions observed lesions, surgery has certain blindness, so generally considered not suitable for general anesthesia, should choose to cervical plexus nerve block and local anesthesia, acupuncture anesthesia or line, to ensure that patients with clear consciousness, can cooperate closely with performer, and guarantee the safety of the operation. It is generally believed that general anesthesia should be the first choice for posterior cervical surgery because of the prone or lateral position. However, local anesthesia can also be used for posterior surgery with relatively superficial surface and short time, such as laminectomy and laminoplasty, because it has fewer complications and is conducive to postoperative recovery. In short, the most effective and appropriate anesthesia method should be selected according to the advantages and disadvantages of various anesthesia methods, the specific situation of the patient, the conditions of anesthesia equipment and the different surgical approaches.
