The first thing you need to do is to go to the hospital and get an infusion, which is the habit of many people seeking medical attention. “This is the principle of rational use of medicines established by the World Health Organization, but in reality, the order has been reversed, and nowadays the infusion rooms of big hospitals are overcrowded with dozens of people getting infusions at the same time. However, there are greater risks associated with infusion compared to other treatment modalities, such as the generation of allergic reactions, which can be fatal in severe cases, and some insoluble particles in the solution, which may cause infusion contamination diseases in the body, resulting in vascular embolism or granulomas in the lungs, pulmonary edema, and venous inflammation, which seriously increase the burden on the body’s metabolism. In addition, the greater harm of infusion also lies in the increase of bacterial drug resistance. The frequent and unreasonable use of antibacterial drugs will make it increasingly difficult to kill bacteria, and eventually will face the dilemma of no drugs available. Only four types of cases can be given intravenously: 1, the selected appropriate drugs without oral formulations; 2, the need to quickly reach high concentrations in infected tissues or body fluids to achieve bactericidal effect, such as infective endocarditis, septic meningitis, etc.; 3, the infection is serious, the situation is progressing rapidly, the need to give emergency treatment, such as bloodstream infection, severe pneumonia patients; 3, patients have obvious gastrointestinal reaction to oral drugs and affect the absorption the patient. As required, patients receiving injectable drugs should be switched to oral administration early when their condition improves and they are able to take them orally. Parents should not talk about infusions and should not use infusions as the only way to get infusions. Hospitals are reducing unnecessary infusions, but if a child has a serious bacterial infection, severe dehydration, acute asthma attack, severe skin allergies and other emergencies that require resuscitation, infusions are inevitable and life-saving. Milder bacterial colds, viral colds, and common coughs, on the other hand, do not necessarily require a drip. The IV usually contains antibiotics inside, which are for bacterial infections and are not effective for viral infections. Doctors will judge whether it is a viral infection based on their own clinical judgment, and only then go for symptomatic treatment. The principle of fever reduction by drip is actually a large amount of cold liquid into the body to achieve cooling. In fact, it is similar to the physical method of reducing fever, but it is dangerous. We can encourage the baby to drink more water, which can also achieve the effect, and it is best to drink water made from oral rehydration salts, which has a small amount of electrolytes and glucose, which can help the baby recover his strength. Saying “no” to outpatient infusions may be a difficult process, but it is in line with the basic principles of modern medicine, which not only reduces the economic burden for patients, but also provides them with a more reasonable treatment pathway, and I hope that patients will establish a correct, standardized, safe and reasonable scientific view of medication.
