Summary

This study aimed to compare three medicines (propofol, etomidate, and ketamine) given to adult trauma patients to help them breathe with a breathing tube. The goal was to see which drug leads to the best outcomes, like survival and fewer side effects. However, the study was withdrawn before enrolling any participants, so no results are available.
