How to insert an indwelling needle with a high success rate?

Indwelling needle is a common method of intravenous needle insertion in daily life. It is very suitable for people who receive frequent or intermittent infusions. Insertion of an indwelling needle can avoid secondary intravenous injections. The indwelling needle can be retained in the human vein for 2-3 days. The insertion method of the indwelling needle is also very simple. The skin needs to be disinfected before insertion. Mastering the method of intravenous injection generally has a higher success rate.

Is the success rate of indwelling needle insertion high?

The success rate of indwelling needle insertion is relatively high and no other side effects will occur

Indwelling needle insertion method

Scope of application

Intermittent, continuous, or daily intravenous infusion therapy. The use of scalp needles should be limited to short-term or single-dose administration to collect blood samples or transfuse blood or blood products, and hemodynamic monitoring should ensure that the infused fluid is in or close to isotonic state and normal pH range (irritant drugs: only intermittent push injection).

Advantages

Easy to puncture, the relevant puncture techniques are easy to learn to protect the patient's blood vessels, relieve the patient's pain, feel comfortable, improve patient satisfaction and nursing quality. There are many different structural products to choose from, and there are catheters of different lengths to choose from to improve the work efficiency of nurses and use drugs rationally, avoid multiple intermittent infusions every day, reduce punctures and delays in medication, avoid reactions between drugs, reduce costs, and reduce the cost of exudation treatment caused by scalp needle puncture.

How to use

1. Items to prepare: Infusion bottle (glass bottle, plastic bag, plastic bottle) Infusion set

Fixing dressing (tape, transparent film)

Connection accessories (heparin cap, needle-free connection)

Flow rate control device (infusion pump, micro pump)

Indwelling needle

Disinfectant iodine, cotton swab

Tourniquet

2. Choose blood vessels: Choose those that are thick and straight with good elasticity and abundant blood flow, and avoid venous valves and joints.

3. Disinfection of skin: The disinfection range is 8*8cm.

4. Apply a tourniquet: 10 cm above the disinfection area, not too tight, and not for more than 2 minutes.

5. Remove the needle cap and loosen the needle core: remove the needle cap vertically upwards and loosen the needle core left and right.

6. Connect the scalp needle and exhaust the air.

7. Puncture: Pull the skin tight, pierce the vein directly, and insert the needle at 15-30 degrees slowly. After seeing the blood return, advance the needle another 0.2cm.

8. Remove the needle core: hold the needle holder with one hand and remove the needle core with the other hand.

9. Insert the catheter: Insert the entire catheter into the vein.

10. Loosen the tourniquet and adjust the drip rate.

11. Sealing and care: Use a sterile transparent patch to fix the tube with the puncture point as the center. Keep the puncture point clean and dry, replace the transparent sticker every 3-5 days, and every 2 days in summer. Replace it in time if it is not sticky or contaminated.

12. Records: Attach a label to the venous puncture site, indicating the puncture date, operator's name, etc. The catheter placement and the name, dosage, and usage of special medications should be recorded daily.
