​What is the impact of the speed of infusion

Modern people need to go to the hospital for treatment in time when they are sick, because if they do not pay attention to their own medical condition, it can easily lead to more serious consequences of the disease. Generally, more serious diseases require intravenous infusion treatment. Infusion is a medical method that gradually introduces drugs into the human body's blood vessels, so many people choose intravenous infusion to treat diseases. However, during the infusion, nurses often tell patients not to adjust the speed too fast or too slow. So, does infusion too fast or too slow have any effect on the body?

1. Too fast a dripping rate can easily cause discomfort

Medication given intravenously consists primarily of water. When this water is pumped into the blood vessels, the amount of fluid in their circulation increases. When this water slowly enters the blood, the human body will automatically adjust and excrete the excess water through the kidneys.

However, if the infusion speed is increased, a large amount of water will flow into the blood. The rapid and large influx will make the body unable to adjust in time, thereby increasing the burden on the human heart. If the patient has a bad heart, it is very easy to cause heart failure. But for normal people, there will also be adverse reactions, such as dizziness, vomiting, etc. This is one of the reasons why people often experience discomfort when receiving an IV drip.

2. Too fast a drip can easily lead to phlebitis

Many drugs now have a stimulating effect on blood vessels, and high concentrations of drugs can also produce many side effects. If the infusion speed is too fast, the concentration of the drug in the local area of ​​infusion and in the blood through which the drug passes will suddenly rise, which can easily irritate the veins and cause adverse reactions such as phlebitis.

3. Too fast dripping rate affects the efficacy

Too fast an infusion rate can easily affect the efficacy. When the drip rate increases, the concentration will also increase, and this high concentration will drop to the lowest point after the drip is completed. Compared with the effective concentration, the duration of this high concentration is relatively short, and the effective drug effect that can be maintained will also be reduced, thereby affecting the efficacy of the drug.

Do you know how to properly infuse?

1. Just the right dripping speed

Too fast a drip rate not only affects the effect of the drug, but also poses certain safety issues. Many patients adjust the drip rate privately, which leads to discomfort symptoms. In severe cases, fainting may occur. Some drugs are very irritating, and dripping them too quickly may increase side effects and harm the body.

2. Follow your doctor’s instructions

If you experience any discomfort during the drip, tell your doctor immediately and stop the infusion of the medication that causes the discomfort. In addition, follow your doctor's other instructions.

3. Needlework

Needle movement is a common occurrence during intravenous drips. The patient will experience local edema. In this case, the liquid should be turned off first, and then the nurse should give the injection again.

4. Dressing change

When the medicine is running low, be sure to ask the nurse to change it in advance, don't forget.

Warm reminder: Some medicines can be dripped faster, while others need to be taken slowly. Therefore, it is best to follow the doctor's instructions during infusion and do not adjust the drip rate without permission.
