Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 80 with risk factors for aspiration who require orotracheal intubation during general anesthesia.

Probably not a fit

Patients with predicted impossible tracheal intubation or significant airway modifications may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of propofol, ketamine, and their combination for rapid sequence induction (RSI) in patients requiring orotracheal intubation. It aims to determine which hypnotic agent provides optimal intubation conditions while maintaining hemodynamic stability. The study is randomized and controlled, focusing on achieving successful intubation on the first attempt without significant hypotension. Participants will be monitored closely during the procedure to assess outcomes.

Why it matters

Potential benefit: If successful, this study could improve the safety and effectiveness of anesthesia induction in patients at risk for aspiration.

How similar studies have gone: Previous studies have explored similar approaches, but this specific comparison of propofol and ketamine in RSI is novel.
