Summary

This trial is testing if longer periods of induced hypothermia are better for patients' neurological outcomes after cardiac arrest, in order to identify the optimal duration of induced hypothermia.

Who is the study for?
This trial is for adults who've been in a coma after being resuscitated from a cardiac arrest outside of the hospital. They must be cooled to below 34 degrees Celsius within 4 hours of the event, with plans to maintain life support for at least 96 hours. It's not for those unstable after resuscitation, with pre-existing severe neurological issues or terminal illnesses, planned early life support withdrawal, sepsis-related arrests, or prisoners.
What is being tested?
The study is testing whether longer periods of induced hypothermia (cooling the body) can improve brain function outcomes in patients who have survived cardiac arrest but are comatose. The goal is to find out how long cooling should last to best protect the brain.
What are the potential side effects?
Therapeutic hypothermia may cause shivering, infection risk increase due to lowered body temperature, electrolyte imbalances like low potassium or magnesium levels which can affect heart rhythm and muscle function, and potential blood clotting issues.
