13. Finally, will special needle into the body cavity to extract secretions, or injection of gas, contrast agent, medicine of a diagnosis and treatment technology. 2 Classification edit site division 1 Brain or spinal cord puncture for diagnosis or treatment. Subdural puncture is commonly used in infants and young children. When the anterior fontanelle is not closed or the coronal suture is expanded, a lumbar puncture needle is inserted into the subdural at the lateral Angle of the anterior fontanelle or from the coronal suture to extract the subdural fluid of traumatic chronic subdural hematoma and purulent meningitis, and then appropriate antibiotics are injected. Ventricle puncture can be divided into anterior horn puncture, lateral horn puncture and posterior horn puncture. A cranial cone is quickly drilled through the skull 2 cm behind the anterior hairline and 2.5 cm beside the midline, and then a lumbar puncture needle or ventricular drainage tube is inserted into the anterior corner of the lateral ventricle. When the brain pressure is too high, the patient is in coma, the pupil is open, the breathing surface is superficial, and the cerebral hernia is formed, rapid ventricular puncture can release the ventricular fluid, and the cerebral hernia can be relieved immediately. It can also measure the ventricular pressure, or connect the drainage bottle to do continuous ventricular drainage, take the ventricular liquefaction test, or inject methylene blue to understand the cerebrospinal fluid circulation. Also can inject air, oxygen, contrast agent from the needle, diagnosis of intracranial lesions and ventricular system obstruction. Iodine allergy should not do angiography. Occasionally, epidural and subdural hematomas are caused by intraventricular fluid drainage. Cerebrovascular puncture can puncture the common carotid artery or the vertebral artery and inject contrast agent for cerebral angiography. The common carotid artery angiography can show the blood vessels in the cerebral hemisphere. Vertebral arteriography demonstrates the subatentorial vessels. Lumbar puncture puncture with lumbar needle puncture lumbar spinal spinal spider under the omentum cavity, it is an important clinical auxiliary examination method of neurology. It can be used to measure cerebral pressure, collect cerebral effusion for routine, biochemical and bacteriological examination, tumor cell and enzyme examination, and provide a basis for the diagnosis of intracranial inflammation, tumor, hemorrhage and white matter demyelination disease. However, when the cranial pressure is too high, lumbar puncture should be careful, it is best not to release fluid, only the cerebrospinal fluid in the hose connected to the brain pressure table to do laboratory tests, so as to avoid cerebral hernia. Contrast agent can also be injected into the subarachnoid space for downward or upward contrast. Air (or oxygen) can also be injected into the subarachnoid space, directional flow to the intracranial, intraspinal lesion angiography, ventricular pneumoencephalography and cisternography. 2 body cavity puncture in the chest Pleural cavity puncture is performed between 7 and 9 costal Spaces under the scapula or the midaxillary line is equivalent to 6 or 7 costal Spaces. Gas can be extracted to treat pneumothorax, inflammatory exudate can be extracted from the pleural cavity, or drugs can be injected to treat pleurisy and relieve symptoms of respiratory distress. The extracted liquid can be used for laboratory tests and bacterial culture. Pericardium puncture is performed from the left midclavicular line between the 5th and 6th costals, outside the dullness boundary of the heart. 3 abdominal cavity and viscera puncture abdominal cavity puncture 1 cm from the umbilical to the midpoint of the pubic line, l ~ 1.5 cm from the side puncture abdominal cavity, for diagnosis
