What happens if you inject an air bubble subcutaneously?

What happens if air enters an IV

When a drug is prepared for injection, it is inevitable that tiny air bubbles will slip into the syringe. If care is not taken to tap them out, they will enter the circulatory system, where, depending on their volume, they may obstruct blood flow.

Do not use Serra Pamies Water for Injectable Preparations: If injected alone into the bloodstream, it can cause red blood cells to absorb water and explode (hemolysis). This occurs because water for injectable preparations does not have the same consistency as blood.

To remove air bubbles from the syringe: Keep the tip of the syringe in the medicine. Gently tap the syringe with your finger to move the air bubbles to the top. Then gently push the plunger to move the air bubbles back into the bottle.

Do not touch the needle. Place the vial with the medication on a flat surface and insert the needle straight through the rubber stopper. Push down on the syringe plunger and inject air into the vial. The air injected into the ampoule will make it easier to withdraw the medication.

What happens if we inject air into an intramuscular injection?

This information will help you learn how to self-administer a subcutaneous injection with a pre-filled syringe. A subcutaneous injection is an injection that is placed under the skin. A prefilled syringe is a syringe that comes with medication inside.

The way prefilled syringes are stored depends on the medication they contain. Most medications are stored at room temperature, but some should be kept in the refrigerator. Your health care provider will tell you how to store syringes. Do not store your prefilled syringes in the freezer or leave them in direct sunlight.

If the medication inside the syringe freezes, place the syringe in the front of the refrigerator or on the refrigerator door shelves so it can thaw. If it freezes more than once, do not use it.

Choose the injection site (a place on the body to give the injection). It should be a site where you can grab a 1 to 2 inch (2.5 to 5 centimeters) fold of skin between your fingers. It is best to use one of the following sites (see Figure 1):

What happens if I do not put the needle all the way in when injecting

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicological Information Service, telephone (91) 562.04.20 indicating the medicine and the quantity ingested.

GlucaGen is supplied in a vial containing glucagon, a white, sterile powder, with a disposable syringe containing the solvent. The powder is compacted. Once mixed, the reconstituted solution contains glucagon 1 mg/ml.

Do not attempt to replace the cap on the needle of the used syringe. Place the used syringe in the orange case and discard the used needle in a sharps container when you have the opportunity.

Administer as a subcutaneous or intramuscular injection. If the patient does not respond within 10 minutes, administer intravenous glucose. When the patient has responded to treatment, administer carbohydrates orally to restore hepatic glycogen and prevent recurrence of hypoglycemia.

Oral carbohydrates should be administered when the procedure is completed, if this is compatible with the diagnostic procedure used. Remember that GlucaGen has the opposite effect to insulin. In endoscopic or radiographic procedures, extreme precautions should be taken when GlucaGen is administered to diabetic patients or elderly people with heart problems.

Why does the syringe become clogged during injection?

Fig. 1: Parallel infusion. Combinations of gravity infusion and parallel pump-driven infusion increase the risk of gas embolism, when gravity infusion runs dry.

The clinical signs and symptoms of air embolism are related to the degree of air entry into the circulatory system. They usually develop immediately after embolization.1

It is generally accepted that any amount of air that could enter the patient should be considered critical. The impact is directly correlated to the patient’s condition, the volume of air, and the rate of accumulation.1
