The drip should not be dripped too fast. Generally, 40-60 drops/min are used for adults, and 20-40 drops/min are used for children, the elderly and patients with certain diseases (such as severe heart disease). Some drugs themselves require slow dripping (such as some irritating drugs), mainly because of fear of adverse reactions. Acanthopanax injection can easily cause allergic reactions (bronchial asthma, skin itching, etc.), respiratory and cardiac arrest and other adverse reactions. Slow drip can closely observe the patient to see if any adverse reactions occur, so that timely detection, timely discontinuation of medication, and timely treatment can be achieved to ensure patient safety
