Less insulin may be just as effective for high potassium

NCT ID NCT06036823

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tested whether 5 units of insulin works as well as 10 units for lowering dangerously high potassium levels in adults. Researchers measured potassium levels two hours after treatment in 384 participants. The goal is to find a dose that is effective but reduces the risk of low blood sugar, a common side effect of insulin.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Hyperkalemia patients with lab potassium levels equal to or more than 5.5 mEq/L (≥ 5.5 mEq/L)+. * Adult: age 18 years or more. * Agreed to participate in the study. * If an investigator decides to start anti-hyperkalemia medications based on the VBG/ABG patient can be enrolled but if the main laboratory value is less than 5.5 mEq/L patients will be excluded Exclusion Criteria: * Cardiac arrest * Hyperglycemia with random blood sugar 20 mmol/L (13) or with acute diabetic complications like Diabetic Ketoacidosis / Hyperosmolar Hyperglycemic State. * Hypoglycemia with random blood sugar (RBS) ≤ 3.89 mmol/l in Diabetic patients and less than 3 mmol/l in non-diabetic patients. * Allergies for any medication in the protocol. * Pregnancy. * Hemolyzed potassium level as reported by the main lab. * Hemolysis, Tumor lysis syndrome, or Rhabdomyolysis due to the ongoing release of potassium. * Acidosis with a pH less than 7.1 will require Sodium bicarbonate (NaHO3). * A patient who will need urgent Furosemide (Lasix), and or dialysis during the study period of 2 hours. * Refused to participate.
