Remifentanil and Remimazolam to Limit Patient Movement

Local anesthetics (LA) may be administered by injection (retrobulbar, peribulbar, subconjunctival, lid, or facial block) or by instillation (topical anesthesia), Considerable drawbacks of local anesthesia in these patients include the fact that a few patients can remain comfortable on an operating table for procedures that exceed two or three hours. Sedation may be helpful with LA to decrease the experience of discomfort, movement and anxiety, which may in turn positively influence hemodynamic parameters, patient satisfaction, and overall improve surgical safety. Sedatives used in eye surgeries include benzodiazepines, opioids, alpha-adrenoceptor agonists, and propofol.
