The addition of adrenaline to the arthroscopic irrigation serum is used during rotator cuff surgery to limit intraoperative bleeding and ensure a clear view. Two concentrations of adrenaline are commonly used in practice: 1mg/L or 0.33 mg/L.

The aim of this study is to determine which of these two doses provides better clarity of the surgical field with less impact on the patient's cardiovascular parameters.


A prospective, randomised, double-blind, multicentre study in two parallel groups of 85 patients comparing two concentrations of adrenaline in the irrigation fluid of an arthroscopy (0.33 mg/L vs. 1 mg/L):

Maximum duration of patient participation in the study = 1 day.

Condition Shoulder Rotator Cuff Tendinitis
Treatment Adrenaline 1 Mg/mL Solution for Injection, Adrenaline 0,33 Mg/mL Solution for Injection
Clinical Study IdentifierNCT05439213
