Bupivacaine and Epinephrine Injection Study

May 12, 2025 updated by: Amin Javer

Bupivacaine With Epinephrine vs Sham Injections During Endoscopic Sinus Surgery: a Double Blind, Randomized Controlled Trial

Endoscopic sinus surgery (ESS) is a common otolaryngologic procedure that aims to remove the partitions that separate the sinus cavities, remove inflamed tissue, and optimize the sinuses for topical medication use. In this procedure, the surgeon will inject a combination of drugs, local anesthetics, and vasoconstrictors, to reduce bleeding and improve visualization. However, previous studies have shown similar results when injected with only saline. In this study, investigators want to determine if the injection of local anesthesic+vasoconstrictor compared to no injection at all makes any difference in improving the surgeon's visualization during an ESS.

Punctures without any medication injected onto the septum

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Boezzart bleeding score
Time Frame: throughout study completion, one day study visit
Change in mean surgical field quality as determined by the Boezzart bleeding score. Boezaart score of 0 indicates no bleeding, whereas the maximum score of 5 indicates severe bleeding (constant suctioning required).
throughout study completion, one day study visit

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total blood loss
Time Frame: throughout study completion, one day study visit
Change in total blood between injection and sham group measured in millilitres
throughout study completion, one day study visit
Surgical time
Time Frame: throughout study completion, one day study visit
Change in surgical time between injection and sham group measure in minutes
throughout study completion, one day study visit
Mean arterial pressure (MAP)
Time Frame: throughout study completion, one day study visit
Change in Mean arterial pressure (MAP) between injection and sham group measured in millimeters of mercury (mm Hg)
throughout study completion, one day study visit
Postoperative bleeding
Time Frame: throughout study completion, one day study visit
Change in postoperative bleeding between injection and sham group measured in mililiters
throughout study completion, one day study visit
Postoperative pain
Time Frame: throughout study completion, one day study visit
Change in postoperative pain between injection and sham group measured with a Visual Analog Scale (VAS) grading from 0 (no pain) to 5 (severe pain)
throughout study completion, one day study visit
