The purpose of this study is to determine if intravenous TXA is a safe alternative to epinephrine in improving arthroscopic shoulder visualization.
- Determine that patients given intravenous tranexamic acid improves surgeon-rated visualization compared to placebo.
- Determine that intravenous tranexamic acid is a safe alternative to epinephrine mixed irrigation fluid to improve arthroscopic shoulder visualization

In the last twenty years, the use of arthroscopy to surgically manage shoulder pathologies has expanded in its indications. The interplay between increased indications, surgeon experience, and improvements in equipment have all propelled arthroscopic shoulder surgery to preferred treatment in managing instability, rotator cuff, and impingement pathology. Obtaining adequate visual clarity is paramount to performing the procedures safely, efficiently, and effectively.
A variety of methods have been employed to improve visualization. This includes tighter control of blood pressure, regional anesthetic, pressure controlled irrigation system, sealed cannulas, electrocautery devices, and injecting epinephrine into irrigation fluid. The use of epinephrine in irrigation fluid has been studied in literature. The results of a few randomized controlled trials demonstrate that the vasoconstrictive properties of epinephrine decrease blood flow and consequently, improves surgeon visualization. However, there has been reports of ventricular tachycardia, lethal arrhythmias, and epinephrine induced pulmonary edema in literature that suggests that the addition of epinephrine in irrigation fluid may have caused these adverse events. Therefore, it is important to examine other alternatives, such as TXA, that can decrease bleeding and improve visualization without potential detrimental effects.
This trial will be conducted in compliance with the protocol, GCP, and the applicable regulatory requirements.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||128 participants|
|Intervention Model:||Parallel Assignment|
|Masking:||Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)|
|Masking Description:||Surgeons are blinded to group allocation as all IV bags will have labels appearing identical when turned away from the surgeon. Anesthetists are told not to reveal allocation to the surgeon as well. And patients will not be informed of their allocation.|

- Visualization Quality Scale [ Time Frame: Intra-operative ]Surgeons are asked every 15 minutes to report on the quality of visualization based on a 4-point scale. Minimum value is 0, maximum value is 3 with the higher value reflecting improved visualization
- Patient Log Book for Pain and Medications [ Time Frame: Day of surgery - post-operative day 14 ]Patients are sent home from surgery with a log book to track the level of pain they are experiencing as well as the medications that they take.
