Harm of intravenous drip

Infusion, also called intravenous drip and infusion, is a very familiar treatment. However, due to the influence of some misconceptions, some people in life require infusion regardless of serious illness and minor illness, and infusion seems to be an essential link in treating diseases. Some people even use infusion as a means to prevent diseases and blindly carry out infusion. According to statistics, in 2009, China used 654.38+004 billion bottles for medical infusion, equivalent to 8 bottles per person per year, far higher than the international level of 2.5-3.3 bottles. Experts remind that infusion is not a "panacea" and it is impossible to "treat diseases from liquids". On the contrary, excessive infusion may also lead to some adverse consequences.

Reduce immunity, minor ailments and hobbies

In the natural state, the human body has a strong defense ability against germs in the surrounding environment. If serious illness or minor illness depends on infusion, it will not only enhance the drug resistance of the human body, but also interfere with the normal defense function of the human body. Infusion drugs directly enter the blood circulation without going through the gastrointestinal tract, which omits the links of humoral immunity and cellular immunity. Over time, it will form an uncontrollable vicious circle and reduce the body's own immune ability.

At the same time, it is easy to suffer from "infusion disease", that is, some people often use infusion to treat minor illnesses such as colds, which makes it difficult to cure the same disease without infusion in the future.

It is easy to damage human liver and kidney.

As the saying goes, "it's a three-point poison." After imported liquid medicine enters the human body, most of it will be metabolized by the liver and eventually excreted by the kidney, which will increase the burden on the liver and kidney. Long-term infusion may damage the functions of organs such as liver and kidney. For example, aminoglycoside antibiotics commonly used in clinic may not only cause renal dysfunction, but also damage hearing.

Especially in children, unreasonable infusion can easily cause drug-induced hematuria. This is because the effective components of most drugs intravenous drip in human body enter the blood and are finally excreted through the kidney. In the process of contact with the kidney, some drugs can directly damage some tissues of the kidney, causing local tissue ischemia, necrosis, etc., and then produce hematuria. Therefore, during the child's medication, parents should pay attention to observation and tell the doctor in time if the child has any discomfort.

Lead to flora imbalance and repeated infection.

There are many bacteria on the surface and in the body. Under normal circumstances, maintaining the balance between flora will not cause disease. Excessive infusion will lead to the inherent flora imbalance of human body, increase the drug resistance of bacteria, and bring unimaginable adverse consequences to future treatment.

For example, some women with recurrent vaginitis can choose some small clinics for infusion treatment, and indiscriminate use of intravenous drip, antibiotics and other drugs will lead to imbalance of vaginal flora, resulting in bacterial resistance or repeated infection. Experts say that in most cases, inflammation in ordinary women can be cured by taking medicine and topical drugs, and usually no infusion is needed to alleviate inflammation. Blind infusion has great disadvantages.

There are uncertain risks in infusion.

Drugs enter the blood circulation directly through intravenous injection without being filtered by the natural barrier of human body. Although the drug effect is faster, if adverse reactions occur, they are often faster and more serious.

Even if aseptic treatment is done before infusion, the solution concentration is reasonable and the speed is appropriate, there are still unpredictable risks in infusion. For example, people who are weak and have poor heart function are very sensitive to changes in body "capacity". Even if only normal saline is injected, it will increase the burden on the heart and cause serious adverse reactions. Experts remind that intravenous infusion is the most unsafe way of administration.

Blood transfusion may cause arteriosclerosis.

Because infusion is the direct injection of liquid medicine into human veins, the iatrogenic diseases caused by infusion can not be ignored. The production, sterilization, dispensing and infusion operation of liquid medicine and mixed drugs for infusion are all manual. Even if it is aseptic operation, every link may be contaminated. Therefore, it may cause different degrees of infusion reactions, such as allergy, fever, serious infection and so on. In severe cases, shock or even death may occur. In addition, infusion is a stimulus to blood vessels. Long-term injection of high-concentration and irritating liquid medicine can easily lead to phlebitis, redness and pain, local body temperature rise and even arteriosclerosis.

Fine particles block capillaries.

Any injection with good quality can't meet the ideal "zero particle" standard. According to electron microscope observation, there are about 300,000 glass fragments and rubber particles (materials of intravenous containers and stoppers) with a diameter of 10 ~ 30nm in each bottle of liquid injected into human body. Because the diameter of human capillaries is only 10 nm, the national pharmacopoeia stipulates that the diameter of insoluble particles contained in liquid should not exceed 10 nm. However, the quality and safety investigation found that many insoluble particles in infusion preparations sold in the market exceeded this requirement, and some even reached more than 50 nanometers.

After the insoluble particles enter human blood vessels, the incubation period in the body can be as long as decades, which may form granuloma, phlebitis and even induce lung tumors. Larger particles can block the small blood vessels of brain, lung, kidney, liver and eyes, which can cause different degrees of tissue necrosis and injury.

How to keep healthy by symptomatic infusion

Everyone should understand the medical common sense that "you don't need intramuscular injection if you can take it orally, and you don't need intravenous infusion if you can inject it intramuscularly". Take a cold as an example. Most colds are viral infections and usually heal themselves in a week or so. The best way is to rest properly, drink plenty of water, supplement vitamins, or take oral anti-cold medicine for treatment. Of course, if a cold patient has severe symptoms such as persistent high fever, poor appetite, frequent vomiting and secondary bacterial infection, it is necessary to find a doctor in time to make a diagnosis and decide whether infusion is needed.

Abrasions, sprains, minor joint injuries, etc. Traditional external application is more reasonable and effective than infusion without fracture and massive bleeding. Generally, cold compress is carried out within 24 hours to reduce local bleeding and swelling and prevent the spread of inflammation. Hot compress after 24 hours to promote the absorption of drugs at the inflammatory site. In this case, neither oral medicine nor infusion is needed, so we should take a proper rest and put the affected area at a level slightly higher than the heart.
