Table 2 Shoulder arthroscopy grading scale (Lands et al., 2019)

From: Dexmedetomidine versus remifentanil infusion for controlled hypotension in shoulder arthroscopy: a comparative study

Grade 1. Excellent—adequate visualization of anatomic structures with minimal need for additional intervention such as electrocautery or temporary altering pump pressure
Grade 2. Good—adequate visualization of anatomic structures with occasional need for electrocautery or temporary altering pump pressure
Grade 3. Average—visualization of anatomic structures requires frequent use of both electrocautery and altering pump pressure
Grade 4. Poor—inadequate visualization of anatomic structures despite using both electrocautery and altering pump pressure
