Why is there an infusion reaction when the liquid temperature is too low?

Causes and solutions of common drops in infusion

Intravenous infusion is based on the principle that the internal pressure of infusion system formed by atmospheric pressure and hydrostatic pressure is higher than that of human vein, and sterile liquid medicine is directly input into vein. In clinical application, it is both common and important. Nurses often encounter the phenomenon that the liquid does not drip and the infusion cannot continue every day. At this time, it is necessary for nurses to master the causes and solutions of common drops in infusion.

1, check whether the infusion set is folded.

The patient's activity is only to pull the folding part of the infusion set apart.

2. The needle slipped out of the blood vessel.

Fluid enters subcutaneous tissue, causing local swelling and pain. The patient's nervousness should be eliminated and another blood vessel should be punctured again. Press the original puncture site for a moment until there is no bleeding.

3. The inclined plane of the needle clings to the blood vessel wall.

This may be related to the patient's activity and unstable stability. Check whether the inclined plane of the needle is close to the blood vessel wall. The position of the needle should be adjusted or the position of the limb should be changed appropriately until the liquid drips smoothly.

4. Is the exhaust needle of infusion set blocked?

The blockage of the vent affects the negative pressure in the infusion bottle and can also prevent the liquid from dripping; After a long time, it will also cause blood to flow back to the scalp. Just change the exhaust pipe.

5. Needle blockage

1) You can hold the infusion tube at the lower end of the dropper with one hand and squeeze the infusion tube near the needle with the other hand. If you feel resistance and there is no blood return after releasing, it means that the needle is blocked, so you should replace the needle and re-puncture.

2) The exhaust needle and the liquid inlet needle are blocked. In many cases, it was initially blocked by a cork when the needle tip caught the cork. When this happens, it must be taken out skillfully with a sterile small syringe. If the rubber stopper cannot be taken out, the infusion set can be replaced again to ensure the smooth infusion.

Blocking removal time should not be too long.

6. The pressure is too low

Due to the poor peripheral circulation of the patient or the low position of the infusion bottle. The position of the infusion bottle can be raised appropriately.

7. Venous spasm

Because patients are nervous about diseases and new environment, the weather is cold, the limbs are bare, and the infusion temperature is low. Can comfort patients and try to eliminate bad conditions, local hot water bottles or hot towels can be used for hot compress!
