What this trial studies

This clinical trial investigates the effects of injecting a combination of bupivacaine and epinephrine during endoscopic sinus surgery (ESS) to determine if it improves surgical visualization compared to a sham injection. The study aims to assess whether this intervention can reduce bleeding and enhance the surgeon's ability to perform the procedure effectively. Participants will be adults scheduled for primary ESS, and the outcomes will be compared between those receiving the active injection and those receiving a placebo.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 years or older who are scheduled for primary endoscopic sinus surgery.

Not a fit: Patients with conditions such as cystic fibrosis, bleeding disorders, or those who have had previous sinus surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved surgical outcomes and reduced complications during endoscopic sinus surgery.

How similar studies have performed: Previous studies have shown mixed results regarding the effectiveness of similar interventions, making this approach somewhat novel.
