The first aid drug used in seizures is diazepam. Seizures are usually manifested as persistent grand mal seizures, which is the persistent state of epilepsy, and this time requires diazepam continuous static dosing to bring the patient’s persistent seizure state under control. If the patient is a small seizure, you can give the patient oral sodium valproate, carbamazepine and other such seizure control drugs, maintain 2-3 days after reaching blood levels, the patient no longer seizures can, so the emergency drug for seizures is diazepam. However, diazepam is a sedative drug, and the patient’s breathing as well as blood oxygen should be monitored when it is applied because sedative drugs have the side effect of inhibiting breathing. Therefore, the application of diazepam during seizures should pay close attention to the patient’s vital signs.
