Epinephrine intramuscular injection method is to choose the gluteus maximus, gluteus medius and other parts of the injection, under the guidance of the doctor according to the patient’s condition to choose the dosage to use, and at the same time monitor the patient’s signs. Epinephrine is a beta receptor stimulant that promotes vasoconstriction and elevates blood pressure, and is used for emergency treatment of shock and critically ill patients. The best way to administer epinephrine is intramuscularly. The intramuscular injection of epinephrine needs to be based on the patient’s condition, and the general location of intramuscular injection is to choose the gluteus maximus muscle, the outer 1/3 of the anterior superior iliac spine to the caudal bone connection to be injected, but also to choose the gluteus medius, gluteus minimus muscle, and even the apical part of the heart to be injected directly. It should be noted that the intramuscular injection needs to monitor the patient’s heart rate, blood pressure, pulse, oxygen saturation and other vital signs response, so as to grasp the patient’s dose of medication. Start administering the drug in small doses to avoid excessive dosage, which may cause sudden rise in blood pressure, cardiac arrhythmia, cerebral hemorrhage, ventricular fibrillation, and so on.
