Many out-of-town patients are determined to have surgery but delayed because they carry incomplete preoperative tests. Therefore, I hereby list the examination items that must be carried by surgical patients: 1, chest X-ray 2, electrocardiogram 3, serum eight items 4, coagulation four items 5, blood routine 6, biochemical full set of tests 7, blood type 8, blood sedimentation 9, C-reactive protein Select examination: 1, blood gas analysis items: (over 70 years old, poor general condition of over 60 years old, patients with lung disorders, etc.) 2, heart ultrasound: heart disease, elderly frail patients 3, pulmonary function: elderly frail patients 4, diabetic patients: fasting blood glucose, two-hour postprandial blood glucose, urine glucose, glycosylated hemoglobin values spine imaging: lumbar disc herniation: lumbar spine X-ray front and side; lumbar spine CT plain scan; lumbar spine MRI. Lumbar spinal stenosis: lumbar spine X-ray front and side, hyperextension, hyperflexion, double oblique film; lumbar spine CT plain scan + three-dimensional creation; lumbar spine MRI. Vertebral compression fracture : Lumbar spine X-ray ortholateral; lumbar spine CT plain + 3D creation; lumbar spine MRI. Note: It is best to be examined at a local tertiary care hospital. For self-contained films, if the quality of the films is good and there is no significant change in the patient’s recent condition, the information within one month may not be necessary to repeat the examination. Patients taking anticoagulant drugs (e.g. aspirin, etc.) need to stop taking them for one week and be prepared psychologically as well as physically before surgery.
