Evaluating how well fentanyl patches work in unstable ICU patients

Pharmacokinetic Study Evaluating the Absorption of Fentanyl From Transdermal Patches in Hemodynamically Unstable Versus Stable Patients Admitted to the Surgical Intensive Care Unit.

Observational Tel-Aviv Sourasky Medical Center · NCT06966869

This study tests how well fentanyl patches work for pain relief in critically ill ICU patients who are either unstable and need extra support or stable and don’t.

What this trial studies

This observational study investigates the absorption of fentanyl delivered via transdermal patches in critically ill surgical ICU patients. It compares two groups: hemodynamically unstable patients requiring vasopressors and stable patients not needing such support. Blood levels of fentanyl will be measured over time to assess absorption differences between the groups. The study aims to determine the viability of transdermal fentanyl for pain management in resource-limited settings or when intravenous options are unavailable.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 admitted to the surgical ICU with a need for pain management using fentanyl.

Not a fit: Patients with well-controlled pain using non-opioid medications or those with severe hemodynamic instability requiring high doses of norepinephrine will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new pain management option for critically ill patients who are hemodynamically unstable.

How similar studies have performed: While the approach of using transdermal fentanyl in ICU settings is not widely tested, similar studies have shown promise in other patient populations.
