Blood is usually drawn from an artery in the wrist. It may also be drawn from an artery on the inside of the elbow, groin, or other site.

What to do if you hit an artery:

1. Untie your tourniquet and pull your needle out immediately.
2. Raise the limb above your head to stop the bleeding, if possible.
3. Apply firm pressure to the wound for at least 10 minutes.

Hitting an artery can be painful and dangerous. Arterial blood travels away from the heart so whatever is injected goes straight to body limbs and extremities. Injection particles get stuck in blood capillaries and cut off circulation. This can result in a lack of blood flow, eventually causing the tissue to die.

Direct puncture nerve injury usually causes immediate symptoms, including: sharp acute pain at venipuncture site. sharp shooting pain up or down the arm. sensation of pain that changes in severity depending on needle position.

Injecting a blood vessel can cause serious complications in rare cases. However, the likelihood of hitting a blood vessel in the subcutaneous fat is extremely rare. More than likely, if there is blood, it is from slight bleeding after the injection.

Bruising after receiving a BOTOX treatment is rare, but it can happen to some. Even the best physicians can cause a patient to bruise after administering BOTOX. It often occurs when the needle knicks a blood vessel, allowing blood to leak below the skin’s surface and causing the surface to appear reddish and/or purple.

If a nerve is hit, the patient will feel an immediate burning pain, which can result in paralysis or neuropathy that does not always resolve.

Injecting a small air bubble into the skin or a muscle is usually harmless. But it might mean you aren’t getting the full dose of medicine, because the air takes up space in the syringe.

If you see blood in the syringe, it means you might have hit a blood vessel. This usually isn’t harmful. If you see blood in the bottom of the syringe (hub) before you push in the plunger: Remove the needle without giving the medicine.

Intramuscular shots are given at 90 degree angle. Needle for IM injections can be 22-23 Gauge, 1-1.5 inches in length, adjusted for thickness of site.

So what’s the big deal with a syringe full of air? Injecting someone with that could create an air embolism, or a potentially fatal blockage of blood vessels that’s caused by air bubbles entering the circulatory system.

In most cases, it will require at least 50 mL of air to result in significant risk to life, however, there are case studies in which 20 mLs or less of air rapidly infused into the patient’s circulation has resulted in a fatal air embolism.

Mortality rate was 21%; 69% died within 48 hours. Thirteen patients had immediate cardiac arrest where mortality rate was 53.8%, compared to 13.5% (p = 0.0035) in those without.

Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death. Saline solutions can also be used to rinse the eyes to relieve irritation or remove foreign objects and/or chemicals.

False. Use a sterile liquid: water or saline. Both tap and toilet water are not safe to inject into your blood. When preparing crack, use Vitamin C powder, not lemon juice or vinegar, which are hard on your veins.

It can be given by injection into a vein, muscle, or under the skin. A non-sterile version may be used in manufacturing with sterilization occurring later in the production process. If it is given by injection into a vein without making it approximately isotonic, breakdown of red blood cells may occur.

Applied to the affected area it is used to clean wounds, help remove contact lenses, and help with dry eyes. By injection into a vein it is used to treat dehydration such as from gastroenteritis and diabetic ketoacidosis. Large amounts may result in fluid overload, swelling, acidosis, and high blood sodium.

Doctors use IV saline to replenish lost fluids, flush wounds, deliver medications, and sustain patients through surgery, dialysis, and chemotherapy. Saline IVs have even found a place outside the hospital, as a trendy hangover remedy. “It has high levels of sodium and chloride, levels that are higher than the blood.

Sensitive Eyes saline solution removes loosened debris and traces of daily cleaner when used as a rinse after cleaning. It can also be used to rinse lens cases as a final (pre-inserting) lens rinse after chemical (not heat) and hydrogen peroxide disinfection.

“Normal” saline is a hypertonic, acidotic fluid. There is no physiologic rationale for its use as a resuscitative fluid. There are many potential problems related to saline. These include causing hyperchloremic acidosis, hyperkalemia, hemodynamic instability, renal malperfusion, systemic inflammation, and hypotension.
