Cardiac neo-triptan is clinically a collective name for three drugs used to resuscitate critical illnesses such as cardiac arrest and anaphylaxis. The names of cardiac neo-triptan needle drugs are epinephrine, atropine and lidocaine. The dosage of their use, too, needs to be adjusted according to the severity of the disease and the disease being treated. In resuscitating adults in cardiac arrest, for example, epinephrine is commonly administered by intravenous push and can be repeated every 3-5 minutes. Lidocaine needs to be used later based on kilograms of body weight and its use is intravenous and can be repeated after 3-5 minutes. Atropine is administered intravenously and can also be repeated. The dose of cardiac neotriptan in children should be calculated based on kilograms of body weight. The above is only a general recommendation, but the specific use will depend on the condition and the doctor’s treatment plan, etc.
