Have you ever had to undergo an operation ? Or have you ever had to undergo some kind of test under anesthesia ? Today we are going to talk about a special medicine that helps doctors relax the muscles in your body and perform the operation or test very safely and easily. The name of this medicine is Atracurium.
Simply put, what is Atracurium?
Atracurium is a medicine that is given to relax the muscles in your body during a medical procedure, such as surgery. It is usually given as an injection.
Imagine a doctor performing a minor operation on your stomach. Wouldn't it be difficult to perform the operation if your stomach muscles were tense? At such a time, when this medicine is given, it temporarily blocks the nerve signals from the brain that tell the muscles to "contract". It's like turning off the switch on a light. Then the muscles relax completely. This means that your body doesn't jerk or move at all. Then the medical team can do their job without any hindrance, very safely.
The important thing is, this is not a medicine you can use at home. This is a medicine that is only given in a hospital or clinic, by a trained medical team .
Things you need to tell your doctor before taking this medicine
Before you have any surgery or anesthesia, your doctor will ask you many questions about your health. It is very important that you answer all of them truthfully. Especially before you are given a medicine like Atracurium, you should definitely tell your doctor if you have any of the conditions listed below.
| The situation you may have | Why is it important to inform? |
|---|---|
| If the body is dehydrated (Dehydration) | When the amount of water in the body decreases, the way medications work can change. Therefore, this information is important to adjust the dosage of medications. |
| If you have heart disease | This medicine can sometimes have a small effect on blood pressure. People with heart disease should be especially careful about it. |
| Lung or breathing diseases (such as asthma, COPD) | Since Atracurium also affects the respiratory system, it is essential that doctors are aware of any existing breathing difficulties. |
| Neuromuscular diseases such as myasthenia gravis | These are diseases that weaken the muscles. So you have to be very careful when giving a muscle relaxant. |
| If you have an allergy to atracurium or any other medicines, foods, or dyes. | If you have had a previous allergy, telling someone about it can be life-saving. |
| If you are pregnant or trying to get pregnant | This information is essential to determine whether or not the medicine will have an effect on the unborn child. |
| If the baby is breastfed | The doctor needs to know this to consider whether some amount of the medicine can pass to the baby through breast milk. |
How is this medicine given and managed?
This medicine is injected into your vein (intravenously). It is done in a hospital by a trained person, such as a doctor or anesthesiologist. So you don't have to worry about it.
- For young children: In some cases, this medicine is given to babies as young as one month old. But it is done with great caution and under special supervision.
- Overdosage: Since this is given in a hospital, the dosage is decided and controlled by the medical team . Therefore, you do not need to worry about an overdose. If you suspect that you have been poisoned by a medicine in any way, you should immediately inform the hospital's Emergency Treatment Unit (ETU). In Sri Lanka, you can call the National Poison Information Center at the Colombo National Hospital for specific information about such poisonings. However, if you are in a hospital, the medical team will take care of all the matters.
