Cardiac arrest

This study tested a dramatic approach: rapidly cooling trauma patients whose hearts had stopped from severe bleeding. Doctors flushed ice-cold saline into the aorta to induce deep hypothermia, then performed emergency surgery to stop the bleeding before slowly rewarming the patie…

This study looked at whether giving less oxygen (aiming for 90-94% oxygen in the blood) right after a cardiac arrest outside the hospital helps more people survive to leave the hospital. It included 428 unconscious adults who had been revived and were on a breathing tube. The tri…

This study looked at 212 patients who woke up after a cardiac arrest outside the hospital. Researchers compared getting a heart angiogram right away versus waiting 12-24 hours. The goal was to see if immediate imaging reduces the risk of death, shock, or another cardiac arrest. T…

This study looked at whether a new anti-shivering protocol helped reduce the need for muscle relaxants in patients cooled after cardiac arrest. Researchers reviewed records of 165 patients treated between 2017 and 2021. The study was terminated early, so results are limited.

This pilot study aimed to see if antiseizure drugs like phenobarbital and levetiracetam change brain connectivity patterns in people with severe acute brain injury and reduced consciousness. Only 5 participants were enrolled before the study was terminated. Researchers used resti…
