Vibrating needles could help make injections less painful | Barber Needles

Noone enjoys having injections, whether they’re for pain relief, disease prevention or booster shots. Getting an injection can be a particularly stressful and traumatic experience for young children and pets, who don’t understand the necessity of the procedure and simply become distressed at the pain and discomfort they feel. It is predominantly hypodermic needles that used to admit injections and pain relief into the skin or via intravenous methods. As a result of this, many individuals suffer from severe phobias and psychological issues as the mere mention of needles, never mind seeing photographs or undergoing the injection procedure. This can make them vulnerable to diseases due to not being protected with the vaccination.

However new research conducted by scientists has explored the reasons we feel pain during an injection and how to lessen this using psychological methods. This odd trick helps to fool the nerves and sensation in your skin to make the injection hurt less.

The report was presented to experts at the American Society of Anaesthesiologists recently. The experiment involved 21 volunteers, which seems to be a very small sample of participants to use. However they discovered some interesting results. Obviously the volunteers involved were not allowed to be repeatedly subjected to an injection using real hypodermic needles, as this is against ethical standards and safety practices.

When the imitation plastic needle was applied to the volunteers’ skin, they also experienced varying levels of heat, cold, pressure and vibration and asked to document their pain levels. This was also measured using neurological monitors which recorded the pain signals experienced.

Researchers found that a certain amount of vibration and pressure applied to the skin 20 seconds before the plastic needle was jabbed into the skin, seemed to be the most effective at reducing the pain levels felt by the participants. It was found that temperature levels did not make a significant difference to their pain levels.

The science behind this phenomena is linked to the Gate Control Theory of Pain. This is where the pain signals that originate from the broken skin, caused by the needle insertion, must pass through “nerve gates”. These are located in the spinal cord and are part of the nervous system before being transferred to the brain. But these gates can be blocked by other physical sensations such as vibrations or pressure. This is why applying pressure to a wound or cut can decrease the pain you feel.

Some dentists already use this vibration technique when carrying out painful and unpleasant procedures.

Many people are afraid of taking injection in his body either through vain or muscle. I have been working on health care and fitness for last ten years. Mostly females are extremely allergic to push injection. But this news of Barber Needles which could help make injections less painful is great.
