All recruiting trials (9)

• Cardiac Arrest: Using Ultrasound to Find Hidden Blood Flow

  This study tests whether patients who have out-of-hospital cardiac arrest but no pulse still show some blood flow on ultrasound and whether that finding relates to survival.

  Recruiting University of Massachusetts, Worcester · Denver, Colorado and 7 other locations · NCT07897370

• Low-dose beta-blocker treatment for adults who survived unexplained ventricular fibrillation

  This trial will try low-dose beta-blockers in adults who survived an out-of-hospital cardiac arrest with no clear cause to see if it reduces dangerous heart rhythms and ICD therapies.

  Recruiting Phase 4 Copenhagen University Hospital, Rigshospitalet · Copenhagen, Dr. and 1 other locations · NCT07405229

• On-scene ECMO for out-of-hospital cardiac arrest in the Moravian-Silesian Region

  This project will try starting ECMO (mechanical heart-lung support) on scene for adults who have a witnessed out-of-hospital cardiac arrest to see if earlier support improves outcomes.

  Recruiting at 2 sites University Hospital Ostrava · Ostrava, Moravian-Silesian Region and 1 other locations · NCT07041086

• ICU clinicians' early judgment of six-month recovery after out-of-hospital cardiac arrest

  This project will test whether ICU doctors and nurses can, within the first 24 hours after admission, predict a patient's six-month brain recovery and quality of life after an out-of-hospital cardiac arrest.

  Recruiting at 6 sites University Hospital, Ghent · Innsbruck and 8 other locations · NCT07026773

• Head‑up, device‑assisted controlled elevation CPR for out‑of‑hospital cardiac arrest

  This registry will track how head‑up, device‑assisted CPR (using an impedance threshold device plus either active compression‑decompression or mechanical compressions) works for adults who experience out‑of‑hospital cardiac arrest.

  Recruiting Hennepin Healthcare Research Institute · Minneapolis, Minnesota · NCT05588024

• Using Argon for Ventilation After Cardiac Arrest

  This study is testing if using argon gas mixed with oxygen can help protect the brain and heart in people who have just been resuscitated after a cardiac arrest.

  Recruiting at 7 sites Phase 2 Mario Negri Institute for Pharmacological Research · Genova, GE and 8 other locations · NCT05482945

• Effect of cooling duration on recovery in children after cardiac arrest

  This study is testing if cooling children who are in a coma after a cardiac arrest for longer periods can help them recover better.

  Recruiting at 62 sites University of Michigan · Birmingham, Alabama and 64 other locations · NCT05376267

• Evaluating the use of transesophageal echocardiography in critically-ill patients

  This study tests how using a special heart ultrasound called transesophageal echocardiography can help critically-ill patients in emergency and intensive care settings.

  Recruiting University of Pennsylvania · Chicago, Illinois · NCT04972526

• Evaluating low versus standard doses of epinephrine for out-of-hospital cardiac arrest

  This study tests whether giving a lower dose of epinephrine can help adults who have a cardiac arrest outside of the hospital more effectively than the standard higher dose.

  Recruiting at 9 sites Phase 4 Unity Health Toronto · Victoria, British Columbia and 8 other locations · NCT03826524
