InSaKa trial: Insulin dextrose infusion versus nebulized salbutamol versus combination of salbutamol and insulin dextrose in acute hyperkalemia: a randomized clinical trial
The InSaKa trial is an important study aiming to find the most effective and safest way to treat hyperkalemia, a condition where the potassium level in your blood is too high. High potassium can be serious, so finding the best treatment is very important. This study is testing three different approaches: giving insulin along with a sugar solution (dextrose), using an inhaled medication called salbutamol (often used for asthma), or giving a combination of both insulin/dextrose and salbutamol. Researchers will carefully measure how much the potassium levels change after treatment and look for any side effects. This information will help doctors know the best way to help patients with this condition.
At a glance
What is this study about?
Hyperkalemia is the medical term for having too much potassium in your blood. Potassium is a vital mineral that helps your nerves, muscles, and heart work properly. However, if levels get too high, it can be dangerous, especially for your heart. This study, called InSaKa, is looking into the best ways to quickly lower high potassium levels. It's a 'Phase IV' study, which means the treatments involved are already approved and generally used, but researchers are now comparing them more closely to see which method is most effective and has the fewest side effects in real-world use.
The study compares three different treatment approaches. One approach uses insulin along with a sugar solution called dextrose. This combination helps move potassium from your blood into your cells. Another approach uses salbutamol, a medication often given as a breathing treatment, which can also help lower potassium levels. The third approach combines both the insulin/dextrose and salbutamol treatments.
The main goal is to see how much each treatment reduces the potassium level in your blood within the first hour. Researchers will also check potassium levels at longer times, such as 3 hours and 24 hours, to see how long the effects last. They'll also monitor for any side effects, including heart rhythm changes, to make sure the treatments are safe. The aim is to gather strong evidence to help doctors choose the best and safest treatment for patients with hyperkalemia.
Key takeaways
- The InSaKa study is looking for the best way to treat high blood potassium (hyperkalemia).
- It compares three treatment options: insulin+dextrose, salbutamol, or a mix of both.
- Researchers want to find out which treatment lowers potassium fastest and is safest.
- Participants will have their potassium levels and heart monitored closely.
- This study aims to improve care for people with dangerously high potassium.
- You can discuss with your doctor if this study might be right for you.
Who may be eligible?
To take part in this study, you would need to be at least 18 years old. There's no upper age limit, so people of all adult ages can be considered. The study is open to both men and women.
The most important requirement is that you have a diagnosis of hyperkalemia, meaning your doctor has found that you have high levels of potassium in your blood. This study is specifically for people whose doctors believe they need immediate treatment for this condition.
There might be other health conditions or medications that would prevent someone from joining, which the study team would discuss with you. These are put in place to ensure the safety and well-being of everyone involved in the research.
- Are you 18 years old or older?
- Do you currently have high potassium levels in your blood (hyperkalemia)?
- Has your doctor said you need treatment for high potassium?
- Are you able to stay in the hospital for monitoring for at least 24 hours?
- Do you want to know more about being part of a medical research study?
This is a guide only — the research team will confirm whether you can take part.
What does participation involve?
If you were to take part in this study, your involvement would begin when your doctor diagnoses you with high potassium levels (hyperkalemia). You would receive one of the study treatments (insulin/dextrose, salbutamol, or both) as decided by the study team. Throughout the study, doctors and nurses would take regular blood samples to check your potassium levels, especially at 1 hour, 3 hours, and 24 hours after treatment. They would also monitor your heart very closely, perhaps using an electrocardiogram (ECG) to watch for any changes in your heart rhythm. You would be watched carefully for any side effects, particularly in the first few hours after treatment. There might be some follow-up checks over a total of 24 hours to ensure your potassium levels remain stable and you are well.

Common questions
What is hyperkalemia?
It's a medical condition where you have too much potassium in your blood, which can be serious, especially for your heart.
What treatments are being tested?
The study is comparing insulin with a sugar solution, a breathing treatment called salbutamol, or a combination of both.
Who can join the study?
Adults aged 18 and over, both men and women, who have been diagnosed with hyperkalemia and need treatment.
What will doctors be checking?
They'll be regularly checking your blood potassium levels, monitoring your heart, and watching for any side effects.
Can I stop participating if I want to?
Yes, you have the right to leave the study at any time, and it won't affect your medical care.
