What are the consequences of blood return from infusion?

In real life, infusion is a common way to treat physical diseases. It achieves the purpose of curing physical diseases by inserting liquids and needles into skin veins to administer medicine. Blood backflow is easy to occur during infusion and acupuncture. Generally speaking, it is caused by inappropriate blood vessels or poor fluid flow. It does not cause any harm to the body and the acupuncture can be repeated.

What are the consequences of blood transfusion?

Generally, when performing an infusion, blood will return from the syringe. This means that the needle has completely entered the blood vessel before the infusion can be performed. This is not harmful. If blood does not return, the needle may pierce the blood vessel wall, and forced infusion will cause local blistering, also known as needle misalignment. However, the blood return time should not be too long. If the blood return time is too long and the infusion has not started, the blood may become viscous and form a clot, which is harmful to the human body.

The hazards of infusion

The dangers of intravenous drip: 1. It causes adverse reactions. Compared with oral medication and intramuscular injection, during infusion, the drugs enter the blood vessels directly without passing through any barriers. Once an allergic reaction occurs, the patient may go into shock or even die within a few minutes. If the infusion rate is too fast, pulmonary edema may occur due to excessive circulatory load. Therefore, patients who are allergic to drugs must undergo a skin test before receiving an IV drip, as severe allergic reactions can be fatal.

The second harm of intravenous drip is that it is easy to get infected. If the syringe, needle and the skin at the injection site are not disinfected strictly during infusion, the needle hole may become red, swollen and festered, and in severe cases, it may cause systemic infection. If you go to a hospital or clinic for an IV drip, you must be careful to observe. If the doctors and nurses are not paying attention, we should pay attention.

The third harm of intravenous drip is that it is time-consuming and costly. This doesn't matter for wealthy families, but I personally feel it is necessary to remind you. An infusion can take as little as one hour and as much as four or five hours, which is obviously more time-consuming than oral medication or intramuscular injection. The same drug at the same dose costs several times or even dozens of times more than oral or other commonly used methods of medication.

The fourth harm of intravenous drip is that it will harm your health if you give intravenous drip too quickly. A bottle of medicine takes two or three hours to be infused, which tests the patience of many people. Therefore, some people simply follow the nurses' example and turn the dial on the infusion tube to speed up the infusion themselves. Many people think that the speed of infusion does not matter, and it doesn’t matter whether the medicine is dripped in a few drops or a few drops. The same medicine that originally took 2 hours may now only take 1.5 hours. In fact, this approach is wrong. The rate of IV infusion is determined by the patient's age, condition, and medications. Generally speaking, the infusion rate for adults is 60 to 80 drops per minute, and for heart patients it is generally less than 60 drops. Patients with severe heart and lung diseases and poor kidney function should try not to receive intravenous drips to avoid increasing the burden on the heart and lungs. If it is necessary to use intravenous drips, the principles of small dosages and slow drip speeds should be strictly adhered to.

Dangers of intravenous drip 5. Pay attention to observation after the intravenous drip. After the infusion, be sure to press the needle hole with a cotton swab for a sufficient amount of time. For most people, it takes 3 to 5 minutes, while for the elderly, due to their poor coagulation function, it takes 6 to 10 minutes. "For some medications, such as antibiotics and antihypertensive drugs, it is best to stay in the hospital for observation for half an hour after the infusion and do not leave immediately," the doctor reminded. During infusion, the medicine flows into the body by gravity (gravity), so the drip is usually hung high on an IV stand. If the height cannot be maintained (such as when some children are held by their parents for infusion), there will often be a "blood backflow" phenomenon, with blood flowing back into the infusion tube, causing panic in the patient. Therefore, during the entire infusion process, you must pay attention to the height of the infusion bottle. Even if you need to walk or go to the toilet, you must ensure that the bottle is above the heart. During the movement, try not to touch the needle or pull the infusion tube, otherwise it may easily cause the needle to shift and puncture the blood vessels, resulting in local subcutaneous bleeding or edema.
