Acute cerebral infarction is the most common type of stroke, accounting for about 70% of strokes in China. Time is brain and time is life. Cerebral infarction can be prevented and treated, with emphasis on prevention, early identification, timely medical consultation and standardized treatment to reduce the occurrence of sequelae and improve the quality of life. Acute cerebral infarction requires early identification and early treatment, so today we will take a look at how to carry out pre-hospital treatment of acute cerebral infarction. I. How to carry out early identification of pre-hospital cerebral infarction 1. Patients at high risk of cerebral infarction Middle-aged and elderly patients with hypertension, diabetes, coronary artery disease, atrial fibrillation, carotid plaque and hyperlipidemia are at high risk of cerebral infarction. 2. Consider the possibility of stroke if the patient suddenly develops the following symptoms: 1) weakness or numbness of one limb; 2) numbness of one side of the face or distorted corners of the mouth; 3) slurred speech or difficulty in understanding language; 4) double gaze to one side; 5) loss or blurring of vision in one or both eyes; 6) vertigo with vomiting; 7) severe headache and vomiting that were rarely seen before; 8) impaired consciousness or convulsions. 3, a brief summary of the most common points of symptoms are: 0 listen (listening to language): slurred speech, difficulty in expression 1 look (1 face): asymmetry, crooked corners of the mouth 2 check (2 arms): parallel lifting, unilateral weakness The key to pre-hospital treatment is to quickly identify patients with suspected stroke and send them to the hospital as soon as possible, with the aim of thrombolytic therapy or intravascular bolus retrieval for appropriate patients with acute cerebral infarction. (2) Take care to identify the patient’s symptoms as early as possible to determine whether the stroke is suspected; (2) Measure the patient’s blood pressure and heart rate quickly; (3) Avoid temporary use of special drugs for anticoagulation or lowering blood pressure until cerebral hemorrhage is excluded; (4) Call 120 or drive the patient to the emergency department of a nearby hospital (a hospital capable of performing emergency CT throughout the day, a hospital with thrombolysis or endovascular retrieval). 5) If there is vomiting, help clean up the patient’s oral contents; 6) Note the changes in the patient’s symptoms so that you can describe them to the doctor for diagnosis. Acute cerebral infarction is sudden and urgent, so families must pay attention to early detection, early identification and early consultation to help patients get better treatment and treatment early. Acute cerebral infarction treatment, every second counts. The treatment principle is to strive for early intravenous thrombolytic therapy. The time from the onset of the disease to receiving intravenous thrombolysis is 4.5-6 hours, and it is very important to arrive at the conditioned hospital for thrombolysis within this “time window” to improve the revascularization and reduce the disability and death rate, and the earlier the treatment, the better the prognosis, and the earlier intravenous thrombolysis can save more brain cells and reduce the death and disability rate.
