How to measure intracranial pressure, and what method is used to measure intracranial pressure

If lumbar puncture is required for cranial pressure measurement, it may not be possible to do it in the outpatient clinic, because after lumbar puncture, it is required to go to the pillow to lie flat for 4-6 hours, and there is no place for you to lie down.

After the lumbar puncture is out of the cerebrospinal fluid, the upper pressure tube is on the top of the scale, isn't it measured? There is anesthesia before lumbar puncture, local anesthesia, and it will definitely hurt when you take anesthetics, but it will not hurt when you do a puncture, and you will definitely be asked to sign an informed consent form before you do lumbar puncture.

Whole cerebral angiography is expensive, you have to open the sheath on your femoral artery, you have to put pressure and bandage after surgery, no one will dare to do it for you if you are not hospitalized, the most painful thing about the contrast is that you can't move your legs after removing the sheath, and you have to keep it for about 8 hours, which is definitely uncomfortable. However, angiography is the most direct and accurate of the vascular examinations. Generally about 5,000 yuan.

If you get a stent, you will get 70,000 or 80,000 yuan, mainly depending on your condition.

Generally, lumbar puncture side intracranial pressure can also be made in the outpatient clinic, there is no need for hospitalization costs related to what tests you do in cerebrospinal fluid, simple lumbar puncture does not have much money if you are hospitalized, it is not necessarily, 1 day is definitely different from 1 month.

Can't do lumbar puncture in the outpatient clinic? As far as I know, the outpatient clinic of Xuanwu Hospital can make an appointment for outpatient lumbar puncture, and if you are in a hurry, you can go to the emergency department at any time!! All need to go to the pillow to lie flat for a few hours. Like the Xuanwu Temple of Heaven, hundreds of patients waiting to be hospitalized cannot be hospitalized because of lumbar puncture.

The intracranial pressure test requires a lumbar puncture, and after the cerebral fluid is punctured, the intracranial pressure is tested by a medical measurement table. Intracranial pressure does not need to be monitored from time to time, and it is easy to injure the patient, so it is enough to observe the patient's vital signs frequently.

Intracranial pressure monitoring is the pressure of the cranial cavity content on the cranial cavity wall, which requires the probe of the intracranial pressure detection detector to be placed in the skull, the probe placed in the forehead and occipital region, and the waveform of intracranial pressure is transmitted to the workstation through the sensor, so as to fully understand the changes in intracranial pressure. By analyzing the changes in the patient's intracranial pressure, it can help to judge the patient's injury and cerebral edema, so as to know the best and estimate the prognosis.

Intracranial pressure can be measured by lumbar puncture. After successful puncture, cerebrospinal fluid flows out of the puncture needle, and the cerebrospinal fluid rises to a certain height in the pressure measuring tube, and does not continue to rise. At this time, the pressure gauge reading is the initial pressure, and after a certain amount of cerebrospinal fluid is released, the pressure measured again is the final pressure.

Normal intracranial pressure is between 80 and 180 mH2O, with less than 80 mmH2O indicating intracranial low pressure and more than 200 mmH2O indicating high intracranial pressure. Brain herniation may cause severe headache, vomiting, or even death, which is cause for concern.

Intracranial pressure monitoring is of great significance for many diseases in neurosurgery. Because intracranial pressure monitoring can not only respond to the severity of the disease, but also be very helpful in guiding** and determining the prognosis. At present, intracranial pressure monitoring methods include epidural, subdural, parenchymal and ventricular implantation of intracranial pressure probes, with intracranial pressure probes implanted in the cerebral ventricles as the gold standard, which can best reflect the actual intracranial pressure values measured in the brain.

The operation method is to locate on the scalp, the puncture point is usually 2-3cm above the hairline, 2-3cm on the side, after the scalp is incised, the skull is drilled with an electric drill, the dura mater is incised, and then the device with a cranial pressure probe is implanted into the brain parenchyma, and the operation is over.

There are two specific methods of intracranial pressure monitoring:

1. Implantation method: A hole can be drilled in the skull, and the probe to monitor intracranial pressure can be placed into the epidural for monitoring. If the probe is placed under the leptomeninges, that is, subleptomeningeal monitoring, the probe can also be placed into the brain tissue for intracranial pressure monitoring;

2. Insertion method: that is, ventricular monitoring method, in the hairline, 2cm in the hairline, next to the midline, the scalp is incised, the skull is drilled, the blood vessels on the dura mater are coagulated through bipolar electrocoagulation, and the ventricular puncture is carried out, the puncture depth is about 5-6cm, and the probe can be implanted to monitor the intracranial pressure of the patient.

Intracranial pressure monitoring refers to the direct monitoring of intracranial pressure through a variety of small intracranial pressure monitors. The principle is to transmit the intracranial pressure to the pressure sensor, and then amplify it through the pressure transducer and scaler and then display the record on the monitor. Depending on where the intracranial pressure meter is placed, there are three ways to measure intracranial pressure:

Intraventricular pressure monitoring (VFP), subdural pressure monitoring (VDP), and epidural pressure monitoring (EDP).
