In most common types of therapeutic shoulder arthroscopy, the addition of epinephrine to irrigation fluid significant improved visual clarity, according to results.
Researchers randomly assigned 101 patients undergoing arthroscopic shoulder surgery to receive either 0.33 mg of epinephrine diluted per liter of saline irrigation fluid or regular saline irrigation fluid. Researchers used a Numeric Rating Scale to rate visual clarity and registered total operation time, total use of irrigation fluid, increases in pump pressure, heart rate, blood pressure and electrocautery use.

Results showed the epinephrine group had a significantly better visual clarity and significantly shorter total operating time. The epinephrine group also had significantly lower total irrigation fluid, according to results.
Researchers found patients who underwent Bankart and superior labrum anterior and posterior repairs experienced the greatest effect on visual clarity and shortening of operation time up to 15 minutes. The addition of epinephrine had no significant effect on heart rate and blood pressure, according to results. – by Casey Tingle
