A lumbar puncture, also called a spinal tap, is a medical procedure used to collect cerebrospinal fluid (CSF) from the spinal column. This fluid surrounds and cushions the brain and spinal cord. A lumbar puncture is performed by inserting a needle into the lower back, between the bones of the spine.
The size of the needle used for a lumbar puncture is important. A small needle can cause pain and increase the risk of infection. A large needle can damage the spinal cord or nerves.
The size of the needle is usually given in millimetres (mm). The most common size is 22 mm. Other sizes include 18 mm, 20 mm, and 25 mm.
The colour of the needle can also be important. Some needles are coloured to indicate the size. For example, a green needle is 18 mm, a blue needle is 20 mm, and a brown needle is 22 mm.

What Colour is a 22g needle?
In the medical field, needles come in a variety of different sizes. The size of the needle is determined by the gauge, which is measured in millimetres. The higher the number, the thicker the needle. A 22g needle is a thin needle that is used for injections and blood draws.
Needles come in a variety of different colours, but what is the significance of the colour of a 22g needle?
The colour of a needle can vary depending on the manufacturer. However, most 22g needles are typically coloured blue or green.
The colour of a needle can have several meanings. For example, in the United States, the Food and Drug Administration (FDA) has guidelines for the colour coding of needles. According to the FDA, the blue or green colour of a needle indicates that the needle is a “hypodermic needle”. This means that the needle is designed for piercing the skin.
The blue or green colour is also intended to help differentiate between different types of needles. For example, a blue needle is usually a hypodermic needle, while a green needle is usually a “medical needle”. A medical needle is a needle that is used for general injections, such as injections of medication or vaccines.
The colour of a needle can also indicate the type of material that the needle is made from. For example, a blue or green needle is typically made from plastic.
The colour of a needle can also indicate the size of the needle. For example, a blue or green needle is typically a 22g needle.
Overall, the blue or green colour of a needle typically indicates that the needle is a hypodermic needle that is designed for piercing the skin. The colour can also indicate the size and type of the needle.
