Effect of a Preoperative Subacromial Epinephrine Injection on Visualization During Shoulder Arthroscopic Surgery: A Randomized Controlled Trial.
Summary
The purpose of this study is to evaluate surgeon-rated visual clarity and the need for increased irrigation pump pressure during arthroscopic shoulder surgery and to evaluate mean arterial pressure, operative time, and any adverse events that occur during arthroscopic shoulder surgery.
