How to remove an indwelling needle?

Now when going to the hospital for infusion, if the patient needs multiple infusions a day, medicine will use the method of indwelling needles, which can greatly reduce the patient's pain. As a patient, as long as you cooperate with the doctor to use the indwelling needle correctly, and master the daily care measures of the indwelling needle, and learn more about the indwelling needle, it is actually good for the patient. Let's learn about the method of removing the indwelling needle.

How to remove the indwelling needle?

It is best to go to the hospital to remove the indwelling needle, because if it is left there for a long time, the needle hole will become very large and infection will occur if the disinfection work is not done well. My son was hospitalized for hand, foot and mouth disease and received intravenous drip for 7 days. After 7 days, the needle hole was very big. The doctor said that he couldn't get it exposed to water to prevent infection. I hope to go to the hospital or clinic and let the doctor help me remove it.

There is only a thin tube, which can be directly pulled out because there is no needle inside the indwelling needle. When the needle is inserted, it is wrapped with a very thin tube on the outside. The tube is still there after the needle is pulled out, so the person or animal who is detained can move around without any danger.

The intravenous catheter is now a hollow soft tube, and the steel needle inside has been pulled out at that time. Removing the intravenous catheter is just like removing an ordinary needle. After removing the needle, use a cotton ball, cotton swab or gauze to press tightly for 2 to 3 minutes to prevent blood vessel bleeding and formation of subcutaneous hematoma.

The preferred site is the upper limbs, followed by the lower limbs and scalp veins. This is because the blood return from the lower limb veins is slow and the drug stagnation time is long, which is more irritating to the lower limb blood vessels and the chance of thrombosis is higher than that in the upper limbs. Especially for those who are bedridden for a long time, the chance of thrombosis is three times that of the upper limbs. If there are special circumstances that require puncture of the lower limb vein, the lower limb can be raised 20° to 30° during infusion to speed up blood return, shorten the retention time of drugs and fluids in the lower limb veins, reduce stimulation to the lower limb veins, and reduce the chance of lower limb venous thrombosis. Do not let the child stand up or walk during nursing to prevent increased blood return and blockage of the tube. The scalp veins are fragile and the subcutaneous fat is thin, making them prone to fluid seepage and compression injuries, so try to choose the upper limbs.

Choice of intravenous catheter

It is advisable to choose a thin and short indwelling needle with an outer sleeve that is flexible, less irritating, can be bent at will and has good elasticity. It is appropriate to choose a pediatric-type indwelling needle to reduce the friction between the indwelling needle and the blood vessel wall, reduce the incidence of mechanical injury phlebitis, and relatively prolong the indwelling time.

Standardized operating technology

Infection is one of the factors that affect retention time. Strictly follow aseptic operation to ensure a sterile environment for the indwelling needle. Routinely disinfect twice and the operator must pay attention to hand hygiene to prevent cross infection.

Correct use of tourniquet can improve the success rate of puncture. Tie a tourniquet 10 cm above the puncture point. Each person should use one tourniquet and disinfect it after ligation. The ligation time should not be too long. Generally, the blood vessels will be obviously filled within 60 seconds of ligation. Avoid ligation for more than 2 minutes as it may cause tissue edema. It should not be too tight (it is appropriate to accommodate one finger) to avoid reducing blood flow in the distal arteries of the limbs and poor venous filling, which will affect the success rate of puncture and increase the chance of subcutaneous hematoma.
