Randomized Controlled Trial Clinical TrialEffects of fentanyl on pain and hemodynamic response after retrobulbar block in patients having phacoemulsification.
To determine the effects of systemic fentanyl analgesia in preventing the pain related to the administration of retrobulbar anesthesia and cataract surgery. ⋯ The results suggest that fentanyl preemptively decreases injection and intraoperative hyperalgesia and provides hemodynamic stability without affecting patient cooperation, resulting in cataract surgery with retrobulbar anesthesia that is comfortable for both surgeon and patient.
