Nurses often snap on needles before injection, do you know why?

It is a "snap" action on a needle. But why do they have to do that?

Different from most other majors, medical students have a minimum of 6 years of study time. This is not uncommon, because when working on the human body, everything must be done very accurately - even from the smallest things.

The act of flicking lightly on a syringe is an example.

Before the injection, every nurse will do this.(Illustration).

This operation must have some meaning so all medical professionals - from nurses to doctors, everyone must follow. But what is that? Do they do that to . color?

Oh no! In medicine, very small jobs can also make a big impact. Here, they do so to push all the air out of the syringe.

Usually, the nurses will point the needle up , gently flick the tube body to help the small air bubbles concentrate on the head of the syringe . They will then press the push lever to get all the bubbles out.

A needle is only ready to perform the task when there is no more gas inside.

A needle is only ready to perform the task when there is no more gas inside - it is a law that cannot be ignored and anyone who works in medicine must remember.

Rules are drawn from tragedies

The action we think is simply this turns out to be the experience drawn from many cases where patients have "died badly" : from difficulty breathing, hypotension, chest pain, muscle pain, joint pain, . up to heart failure, respiratory failure, loss of consciousness, stroke . These frightening symptoms are the result of letting air enter the body, causing a blockage.

Bubbles seem to be very harmless, when they enter the bloodstream can make the circulatory system miserable. They will just stay there and hinder the flow of blood, leading to incalculable hazards.

Air bubbles in blood vessels.

When a congestion based on symptoms is detected or by methods such as using ultrasound, CT scans, the doctor will choose to correct the problem for each case.

Doctors may just need to guide the patient to sit in a position, so that the balloon does not enter important places like the heart, lungs, brain. Can stimulate heart palpitations, give oxygen to compensate for the circulatory system stagnation then.

Break a very small rule - and you can kill a life.

These two ways of delaying bad consequences, waiting until the vascular wall absorbs all the bubbles is safe. Some emergencies will require surgical intervention.

Vascular obstruction with healthy adults is unlikely to be dangerous. But if it's a patient with heart failure, putting air bubbles in the bloodstream is almost certainly a death sentence.

Break a very small rule - and you can kill a life. This is not only a person who needs medical care to remember, but we also have to memorize it. Because this danger can also occur during infusion.
