Imagine that you have to undergo an operation. The doctors perform it by anesthetizing you, which means completely unconscious. But what happens if your muscles suddenly twitch or twitch? That can be a big obstacle to the surgery, right? Today we are talking about a special injection that stops such sudden movements and helps doctors do their job safely and easily. That is pancuronium.
Simply put, what is Pancuronium?
Pancuronium is a muscle relaxant . Its main function is to completely relax your body's muscles and keep them from moving during surgery or other medical procedures.
Imagine that your brain is like the boss of a company. Your muscles are your employees. The boss (the brain) sends nerve signals to the employees (the muscles) to "contract" and "move." What this pancuronium does is temporarily block the pathway through which those signals travel. Then, since the muscles don't receive the commands from the brain, they are completely relaxed and have no movement. This allows the doctors to perform surgery without any hindrance.
This is usually used in conjunction with anesthesia. It is also sometimes used to help patients who are having difficulty breathing breathe by connecting them to a machine (ventilator).
Things you need to tell your doctor before giving this medicine
This is very important. It is essential that your doctor knows your complete health history before prescribing this medication to you. This is because some medical conditions require special care when using this medication.
See the table below. If you have any of these conditions, be sure to tell your doctor about them.
| Situation you need to report | Why is that? (Simply) |
|---|---|
| Dehydration - lack of water in the body | When the body's fluid balance changes, the way medications work can also change. |
| Heart disease | This medication may have some effect on heart rate and blood pressure. |
| Kidney disease | If your kidneys are not working properly, it will take longer for this medicine to leave your body. Therefore, the effect of the medicine may last longer. |
| Liver disease | The liver is where most medications are broken down in the body. If there is a problem with the liver, the effects of the medication may change. |
| Lung or breathing disease - e.g. Asthma, COPD | Because this medicine also relaxes the respiratory muscles, special care should be taken in people who already have respiratory diseases. |
| Myasthenia gravis - a disease that causes muscle weakness | People with this condition may be hypersensitive to muscle relaxants, so they may need a very low dose. |
| Allergies | If you have an allergy to pancuronium or any other medicine, food, or dye, be sure to tell us. |
| If you are pregnant or trying to get pregnant | The doctor should be concerned about the effects of the medication on the pregnant mother and baby. |
| If you are a breastfeeding mother | It is important to consider whether the medication passes to the baby through breast milk. |
