Shall we talk about the pain-relieving Bupivacaine Injection? (Bupivacaine Injection)

Have you ever had a minor surgery, a tooth extraction, or a cut on your body that needed stitches? Remember the injection the doctor gave you to numb the area? We don't feel any pain at that time, right? Well, today we're going to talk about a special medicine that's used to temporarily stop pain in a certain part of the body. Its name is Bupivacaine.

Simply put, what is Bupivacaine?

Bupivacaine is a type of medication called a local anesthetic. Simply put, it temporarily numbs a specific area of ​​your body. This stops the pain signals from the nerves in that area from going to the brain for a while. That's why you don't feel any pain. Think of our nervous system as a network of telephone wires. When we get injured somewhere, a message goes along that wire to the brain saying, "It hurts here." What Bupivacaine injection does is go to the location of that message and temporarily disconnect that connection. Then, the message doesn't get to the brain, so we don't feel any pain. It is commonly used to:

• Numb the area before minor surgery .
• Extract teeth or treat teeth.
• Stitch a wound.
• Like an epidural given to a mother who is about to give birth to a child to reduce pain.
• It is sometimes used to control pain after surgery.

Things you need to tell your doctor before giving you this medicine

Okay, now before giving you this medicine, the doctor will ask you about your health condition. This is very important. Because your safety comes first. Therefore, if you have any of the following conditions, you must definitely tell the doctor without hiding it.

• Allergies : Tell us if you have any allergies, not just to Bupivacaine , but to any other medicine (especially other anesthetics), food, dye, or preservative.
• Heart disease : If you have any heart disease.
• Liver or Kidney disease : If there is any problem with the functioning of these organs.
• Low blood pressure: If you have low blood pressure.
• Lung disease: If you have any breathing related condition.
• G6PD deficiency: This is an inherited enzyme deficiency that affects our red blood cells. If you know you have this condition, be sure to tell your doctor.
• Pregnancy or breastfeeding: It is essential to inform your doctor if you are pregnant, trying to become pregnant, or breastfeeding .

By knowing these things accurately, your doctor can safely decide whether to give you this medication, use another alternative, or change the dosage.

How do you use this medicine?

This is not a medicine you can buy at a pharmacy and take home. Bupivacaine is a medicine that is only given as an injection in a hospital or clinic by a qualified doctor or trained medical staff . This is because your heart rate, blood pressure, and breathing need to be monitored while this medicine is being given.

Do you give this to children?

Children over the age of 12 can use this medicine in some special cases. But it should be done with great caution and under special medical supervision.

What do you do if the dose increases?

This is given in a hospital, so the chances of this happening are very low. The medical staff will know exactly the correct dose for you. However, if there is any suspicion that you have taken too much of the medicine, the medical staff will take the necessary measures immediately. So you don't need to panic. If you have any problems outside the hospital, go to the nearest hospital's Emergency Treatment Unit (ETU) immediately. If you suspect poisoning, call the National Poisons Information Centre at the National Hospital .

What are the side effects? Should I be afraid?

Like any medicine, Bupivacaine has a small chance of causing side effects. However, these are not common. Also, since you are under medical supervision when you are given this medicine, any problems can be treated quickly. However, it is important for you to be aware of these. Let's break these side effects down into two categories. Some are serious and should be reported immediately. Others are usually less serious and go away after a while.

Bupivacaine Side Effects Symptoms that should be reported to the doctor or nurse immediately Symptoms that are usually not serious, but should be reported to the doctor if they persist

Allergic reactions	Skin rash, itching, swelling of the face, lips, tongue or throat, difficulty breathing.
Heart rhythm changes	Feeling like your heart is beating fast or irregularly, dizziness, chest pain.
Low blood pressure	Severe dizziness, blue eyes, inability to stand.

Anxiety or nervousness	Feeling a strange fear and uneasiness.

Things to be careful about after taking the medicine

This is the most important thing to pay attention to on your part. After the Bupivacaine injection, the area will be numb for a few hours.

The most important thing is to protect the area from harm while it is numb. Since you don't feel the pain, the area is more likely to be cut, bruised, or burned.

For example, imagine that you were given this medicine to extract a tooth. As long as your cheek and lip on that side are tingling, you are very likely to bite that area, drink hot tea and burn your mouth. Therefore, be very careful about what you eat and drink until the tingling is completely gone. Also, if you have a tingling area on your arm or leg, you should protect that area from being hit by anything sharp or hot. Because you don't feel it even if it hurts.

Can there be problems with other medications?

Yes, absolutely. Bupivacaine can interact with some other medications. That's why it's important to tell your doctor about all the medications you're taking, including vitamins, herbal products, and pain relievers . It's especially important to tell your doctor if you're taking any of the following medications:

• Acetaminophen (such as paracetamol)
• Some types of antibiotics (e.g. dapsone, sulfonamides)
• Antiepileptic drugs (e.g. phenobarbital, phenytoin)
• Other numbing medications (e.g. lidocaine)
• Some medications for heart disease (e.g. nitroglycerin)

This list is not complete, so it's best to tell your doctor about everything you take. Also, tell him if you smoke or drink alcohol.
