Comparing opioid-based and opioid-free methods for intubation

The Effect of Opioid-free Anesthesia on Hemodynamic Response and Nociception Level Index During Laryngoscopy and Intubation

Not applicable Interventional Aretaieion University Hospital · NCT06464393

This study is testing whether using an opioid-free method for intubation can lead to better health responses during surgery compared to the traditional opioid-based approach.

What this trial studies

This study investigates the effects of opioid-based versus opioid-free induction on hemodynamic responses and nociception levels during elective surgeries. It aims to compare the hemodynamic response to laryngoscopy and intubation between two groups: one receiving opioid medications and the other receiving a combination of lidocaine, dexmedetomidine, and ketamine. The research addresses the common practice of using opioids to mitigate sympathetic responses during intubation, while also considering the side effects associated with opioid use. The goal is to evaluate the potential benefits of an opioid-free approach in improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adult patients classified as ASA I-II with Mallampati classifications of 1, 2, or 3.

Not a fit: Patients with anticipated difficult airways, chronic opioid use, or certain cardiovascular conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer intubation practices with fewer opioid-related side effects for patients.

How similar studies have performed: Previous studies have shown promising results for opioid-free techniques in improving postoperative recovery, suggesting potential success for this approach.
