My father suddenly fainted this morning and fell to the back of his head. The doctor said it was subarachnoid hemorrhage. What should I do?

Only subarachnoid hemorrhage? Are there any obvious brain contusions and lacerations? Any intracranial hematoma? How is the patient now?

Because the specific situation is unknown, I will briefly talk about my personal views for reference only.

If the patient is generally in good condition and conscious, only symptoms such as headache, dizziness, nausea, vomiting, no fever, no convulsions, no unconscious disorder, no physical activity disorder, no incontinence. Imaging examination showed no obvious brain contusion and laceration, and no intracranial hematoma. If it's only subarachnoid hemorrhage, it generally recovers well. Treatment: 1, using hemostatic 1-3 days, and then changing to drugs for promoting blood circulation and removing blood stasis and improving circulation; 2. Use drugs that dehydrate, reduce intracranial pressure, nourish brain cells and protect brain tissue; 3, give other symptomatic drugs (such as bad diet and vomiting, anti-vomiting, fluid replacement, nutritional support and other drugs, such as severe headache, symptomatic headache treatment drugs); 4, lumbar puncture to understand the level of intracranial pressure and the nature of cerebrospinal fluid, and replace bloody cerebrospinal fluid to promote the renewal of cerebrospinal fluid, such as cerebrospinal fluid is obviously bloody, blood volume is more, lumbar puncture catheter is feasible when necessary; 5, according to the situation can choose other treatment methods, such as hyperbaric oxygen.

If subarachnoid hemorrhage is not treated actively, long-term blood stimulation may lead to hydrocephalus. It is necessary to observe the changes of the condition and review the head CT regularly.
