Introduction
A brain tumor is a space-occupying lesion within brain tissue. The risk level of brain tumor surgery depends on the tumor's size, nature, and location. If the brain tumor is located on the convex surface of the cerebrum, is relatively small in size, and has no clear connection with surrounding nerves and blood vessels, it is generally easier to remove surgically, and the surgical risk is relatively low.
Brain tumors are space-occupying lesions within brain tissue. The risk level of brain tumor surgery depends on the tumor's size, nature, and location.
If the brain tumor is located on the convex surface of the cerebrum, is relatively small in size, and has no clear connection with surrounding nerves and blood vessels, it can usually be easily removed during surgery, resulting in relatively lower surgical risk. However, if the tumor is situated in functional areas such as the brainstem, in regions difficult to access surgically, or closely adhered to or wrapped around critical surrounding nerves and blood vessels, complete removal may be difficult, and there is a higher risk of intraoperative complications such as massive hemorrhage and neurological deficits; thus, the surgical risk is generally greater.
After brain tumor surgery, close monitoring of the patient's respiration, pulse, blood pressure, body temperature, and level of consciousness is essential. Additionally, changes in pupil response should be observed to prevent serious complications such as intracranial hemorrhage and brain herniation. For unconscious patients, precautions must be taken to prevent vomiting and aspiration, while also actively preventing pulmonary infections, urinary tract infections, and pressure ulcers.
