Increasingly high muscle tone in comatose patients undergoing craniotomy may be a clinical symptom triggered by the disease itself, or it may be a complication arising from the surgery. If the patient himself suffers from cerebral hemorrhage, cerebral infarction, brain tumor and other diseases, the disease itself will cause corresponding damage to the patient’s brain tissue, causing the patient to experience abnormal symptoms such as increased muscle tone, dizziness, headache and so on. If the surgical process causes damage to the patient’s cranium and brain, resulting in complications such as cerebral edema, it is easy to induce symptoms such as increased muscle tone, nausea, vomiting and so on. If you want to improve the phenomenon of increased muscle tone, you need to treat the cause of the disease. For example, patients with cerebral infarction can be treated with intravenous infusion of vincristine and other drugs that dilate cerebral blood vessels. You can also use botulinum toxin, baclofen and other drugs to reduce muscle tone as prescribed by the doctor. When the patient is awake, give him regular functional training to relieve muscle tension and promote the decline of muscle tone. If the craniotomy coma patient’s muscle tone is getting higher and higher, it is necessary to follow the doctor’s instructions for professional treatment as soon as possible.
