How to care after brain cancer surgery? What are the diagnostic methods for brain cancer?

Brain cancer lesions appear in the skull, which makes treatment difficult. Because surgery can easily damage important nerves and often leave residual lesions, postoperative observation and scientific care are very important. The patient's family and medical staff must observe the patient's condition at all times, and should assist the doctor in handling any abnormalities.

What are the key points in postoperative care for brain cancer?

1. Postoperative care for brain cancer surgery should follow general surgical care routines and post-anesthesia care routines.

2. Patients who have undergone general anesthesia after brain cancer surgery should lie flat before waking up from anesthesia, with their heads turned to the healthy side. If the blood pressure is stable after waking up from anesthesia, the head can be raised about 30 degrees.

3. Do not eat on the day of brain cancer surgery. You can eat liquid or semi-liquid food on the second day or follow the doctor's advice.

4. Pay more attention to the observation of the condition. After brain cancer surgery, pay attention to the observation of consciousness, pupils, and pulse once an hour for 6 consecutive times, every 2hl for 12 consecutive times. Measure blood pressure once an hour for 6 consecutive times, every 2hl for 3 consecutive times. Stop observation after the condition is stable for 3 days. If the condition requires, continue observation according to the doctor's advice.

How are brain cancer diagnosed?

1. Imaging examination

These include cranial X-rays, radionuclide brain angiography, ventriculography and cisternal angiography, and cerebral angiography. These examinations were once important diagnostic methods for neurological diseases, not only for locating lesions, but also for qualitative diagnosis. However, except for X-rays, these examinations are all damaging and should be carefully selected according to needs.

2. CT examination

CT has a very high diagnosis rate for intracranial tumors and is one of the main diagnostic methods for brain tumors. Intracranial tumors are histologically quite different from normal brain tissues. Different tissue structures have different CT values ​​and show different densities, thus showing lesions on CT images.

3. Magnetic resonance imaging

MRI can provide clear anatomical background images, especially head images that are not disturbed by artifacts in the posterior cranial fossa, with clear contrast between gray and white matter in the brain, and can be used for coronal, sagittal and axial section faults, which is superior to CT. Intravenous injection of a paramagnetic substance, gadolinium (Gd) compound (Gd-DTpA), can significantly shorten the T-1 relaxation time of tissues, so it can be used as an enhancer to increase the contrast between lesions and normal brain tissues and improve the resolution of MRI. It is now generally believed that MRI should be the first choice for the diagnosis of neurological lesions.
