Who invented the 360 degree circle?


What is the origin of 360 degrees in a circle?

A full circle is 360 degrees because the Babylonians used the sexagesimal system. It also represents the number of days a year and also because 360 is highly composite.

What is 45-degree angle injection?

Intramuscular (IM) Injection Guidelines Injections should be administered at a 45-degree angle, typically into the subcutaneous tissue over the anterolateral aspect of the thigh for infants up to 1 year or the upper outer triceps region for adults and children aged 1 year and older.

What are the different angles of injection?

Intramuscular at 90 degrees (left), subcutaneous at 45 degrees (center), and intradermal at 15 degrees (right).

Is Z track best practice?

The z-track technique minimises leakage of the drug at the site of injection, minimises pain (Workman, 1999; Chadwick and Withnell, 2015) and has fewer adverse effects (Strohfus et al, 2018). It is recommended for all injection sites (Rodger and King, 2000).

Is Z track method still used?

Even though the literature has supported the z-track for years (not vaccines), current evidence may not be fully used in practice.

Why do I bleed after a shot?

None of them are a cause for concern, or a reflection on your injection technique. If you see blood at the injection site after the needle is removed, you likely nicked a small blood vessel at or below the skin surface, and blood is following the needle track out to the surface.

When should you use Z track method?

YOU SHOULD USE the Z-track method for all I.M. injections in adults. By leaving a zigzag path that seals the needle track, this technique prevents drug leakage into the subcutaneous tissue, helps seal the drug in the muscle, and minimizes skin irritation.

What size needle is suitable for all ages?

A 23-gauge or 25-gauge needle is recommended for intramuscular administration of most vaccines (Plotkin and Orenstein, 2008). For intramuscular injections in infants, children and adults, therefore, a 25mm 23G (blue) or 25mm 25G (orange) needle should be used.

What happens if you hit bone during IM injection?

A needle that is too long can penetrate the deltoid muscle, hitting the bone. Although patients will not feel their bones being hit, the vaccine might not fully absorb into the muscle, leading to a reduced immune response.
