This clinical trial is focused on studying the treatment of in-hospital cardiac arrest, a condition where the heart suddenly stops beating while a patient is in the hospital. The trial will investigate whether using a treatment called sodium bicarbonate can help improve the chances of the heart starting to beat again on its own, compared to a placebo. Sodium bicarbonate is a chemical compound that is sometimes used in medical emergencies to help balance the body’s pH levels.

Participants in the study will receive either sodium bicarbonate or a placebo during the event of a cardiac arrest while they are in the hospital. The treatment will be given through an intravenous injection, which means it will be administered directly into a vein. The main goal of the study is to see if sodium bicarbonate can increase the likelihood of the heart resuming its normal function, known as the return of spontaneous circulation.

The study will also look at other important outcomes, such as survival rates 30 days after the cardiac arrest and whether patients have a favorable neurological outcome, which refers to the brain’s ability to function well after the event. This will be assessed using a scale that measures the level of disability. The trial is designed to provide valuable information on whether sodium bicarbonate can be an effective treatment during in-hospital cardiac arrest.
