É vantajosa a adição de epinefrina na solução de infusão artroscópica no tratamento da lesão do manguito rotador?

Abstract

ObjectiveTo evaluate the use of epinephrine in arthroscopic infusion serum as a measure to improve the quality of surgical viewing during procedures for treating rotator cuff tears. MethodsThis was a prospective randomized double-blind comparative study in which 49 arthroscopic repair procedures on rotator cuff tears were evaluated. Patients presenting ASA I and II surgical risk were included. The patients were placed into two groups: the first with epinephrine (1mg/L) in the infusion serum and the second with pure physiological solution. A single surgeon was responsible for the procedures, without knowledge of the medication usage. The surgeon rated his quality of viewing during the operation, on an increasing scale from 0 to 10. Interscalene block or suprascapular nerve block was chosen randomly and used in association with general anesthesia. The anesthetist issued final report relating to possible intercurrences. ResultsThe group with epinephrine received an average score of 9.29 and the group without epinephrine received an average score of 7.16. The difference was statistically significant (p < 0.05). There was no important clinical alteration relating to use of this drug. ConclusionAs well as being safe, addition of epinephrine at a concentration of 1mg/L to the infusion serum was shown to be effective for improving the visual field during arthroscopy to repair rotator cuff injuries.
