Do you have such people around you: in winter, you go to infusion to expand blood vessels and think it can prevent stroke; If you want to recuperate your body, ask the doctor to give you some nutrient solution; No matter serious or minor illness, I hope infusion can shorten the course of disease... Is infusion really so magical? Pharmacists introduce several misunderstandings about infusion and help you treat infusion scientifically. Infusion can get better quickly? wrong! The fast pace of work and life and the attendant pressure make people who "focus on speed" more and more unable to afford to spend on diseases. The concept of "fast infusion" makes infusion their preferred mode of administration. During infusion, the drug directly enters the blood circulation and takes effect quickly, but the current research can not confirm that its curative effect is better than other administration methods. Oral administration enters the blood through the digestive system, and the process is slow. Some impurities that may cause adverse reactions are "treated" in the digestive tract. Therefore, the adverse reactions are also mild, and gastric lavage can be used in case of adverse reactions. The absorption of drugs injected subcutaneously and intramuscularly also takes some time, creating conditions for first aid. However, there is no absorption process during infusion, so adverse reactions will be faster and more violent. Serious and minor diseases need infusion? wrong! "Infusion when sick" has become a medical habit of some people. Especially in pediatric clinics, parents' "love for their children" has made Pediatrics a "disaster area" for infusion. For example, the vast majority of colds are caused by viruses. The course of the disease is generally one week. Patients can recover in about a week as long as they have a proper rest and drink more water, even without medication. The phenomenon of random infusion and abuse of antibiotics in the treatment of colds is very common, which will destroy the normal flora in the human body, lead to the imbalance of flora and the reduction of immunity; It will also accelerate bacterial drug resistance, and even create "super bacteria" that will not invade 100 drugs, and eventually no drugs are available. The result is that the "enemy" is stronger and stronger, but he is weaker and weaker. No disease prevention and supplementary nutrition? wrong! Some old people will take the initiative to request the infusion of drugs that promote blood circulation and reduce blood viscosity to dredge blood vessels, maintain the body and prevent diseases such as cerebral thrombosis. However, this treatment lacks scientific basis at present. After doctors refused such unreasonable requests, they were also questioned by patients as irresponsible. Elderly patients, especially chronic patients with many varieties of drugs, may increase the burden of liver and kidney; For the elderly with cardiac insufficiency or heart failure, a large amount of infusion will increase the heart load, which is harmful to health. Some parents also require glucose infusion in order to quickly supplement nutrition for candidates. This "treatment" is also of little significance. Infusion without illness is like making trouble without incident. It not only wastes resources, but also may cause adverse reactions. Is infusion absolutely safe? wrong! It's a big mistake if you think the infusion is safe. Infusion is recognized as the most risky way of administration, which is regarded as a small operation abroad. It is reported that about 60% of the adverse drug reactions in China are caused by intravenous administration. Infusion can often cause allergic reactions such as fever and rash. In severe cases, anaphylactic shock or even death may occur. The more kinds of imported drugs and the longer the course of treatment, the probability of adverse reactions will increase exponentially. At the same time, the injection is more prone to errors and more serious consequences than other dosage forms in the process of configuration and use. Abusing infusion is like "shooting mosquitoes with cannons". Mosquitoes are dead, but they waste money and hurt their bodies by mistake. Know more This is the principle of scientific medication Clinical medication should follow the principle of "no need if you can, no more use if you can use less; no intramuscular injection if you can take orally, no infusion if you can intramuscular injection". Only when the patient has difficulty swallowing and serious absorption disorders (such as vomiting, severe diarrhea, etc.) and is unable to take oral drugs; At the same time, intravenous infusion can be used only when the condition is critical, develops rapidly, and the drug needs to reach the effective concentration in the tissue quickly. At present, more and more hospitals in China have cancelled outpatient infusion. Patients should be fully aware of the risk of infusion, do not take the initiative to request infusion when seeing a doctor, and follow the doctor's advice for treatment. Do not abuse infusion in order to treat minor diseases, resulting in serious adverse reactions. (outlook new era)
