During this period, mycoplasma-infected pneumonia was prevalent in many places across the country, particularly affecting children. Many children had to be given continuous infusions for more than ten days to recover. At this time, many parents, especially those born in the 1980s, can’t help but recall the butt injections they often used when they were children. Although people were afraid of injections back then, in many cases, one or two injections would cure the disease. It was not as troublesome as taking a lot of medicines and infusions now.

But why did the butt needle disappear?

Buttock injection, also known as intramuscular injection, refers to a method of intramuscular injection at the appropriate part behind the buttocks, which is relatively conservative and safe.

Because human buttocks muscles and fat are thicker and less irritating, it is less likely to pierce deeper blood vessels during main photography, and it can also avoid damaging bones.

At the same time, the buttocks muscle tissue is loose and rich in blood vessels, which is conducive to drug absorption.

In addition, muscle absorption is much slower than intravenous injection, and intramuscular injection can effectively reduce allergic reactions.

As for why spanking needles have “disappeared” now, there are a number of reasons:

-Drug updates

In the past, some drugs could only be injected intramuscularly, such as some penicillins, but now they have been replaced by various cephalosporins, which are safer and there is no need to pierce the buttocks.

- Strong pain

Because the buttocks are thicker, the needle needs to penetrate about 3 centimeters to reach the muscle, which may account for about 2/3 of the needle. The buttocks are rich in blood vessels and nerves. Intramuscular injections will cause obvious pain, especially children, who will be very scared and easily affect the injection effect.

- Stimulate nerves

There is the sciatic femoral nerve in the buttocks. If the injection technique is not perfect, the nerve may be easily damaged if it is stimulated, and even affect walking.

At the same time, there is also a femoral artery in the buttocks, which can easily cause bleeding if it is punctured.

If intramuscular injections are used for a long time, it is easy to cause symptoms of subcutaneous induration and congestion, and some injections can even cause muscle atrophy.

- Small injection volume

Generally, a maximum intramuscular injection is 4 ml, while an intravenous injection (infusion) can reach several thousand ml.

-inconvenient

Intramuscular injection requires taking off pants, which is often embarrassing especially for women.

-Patient needs

As patients, we all hope to get better soon. Many people believe that infusion is the most effective. Some surveys even show that nearly half of the patients in outpatient injection rooms take the initiative to ask for infusion from doctors.

- Fees vary

Infusion also brings more profits to the hospital. It is said that the cost of a day's hanging injection is on average several times that of a spanking injection.

Of course, buttock injections have not disappeared completely. They are still needed in some cases, such as when intravenous injection is not suitable or impossible, when it is required to produce curative effect more quickly than subcutaneous injection, or when injecting drugs with strong irritation or larger doses, etc.
