This also increases the frequency of complications, such as globe perforation and peribulbar hemorrhage .\n\nTo prevent this and to increase tissue perfusion, hyaluronidase and other adjuvants such as clonidine, epinephrine and alkalinization of local anesthetics were used to improve peribulbar block.\n\nHyaluronidase may reduce tissue viscosity , which facilitate the complete diffusion of anesthetic solution along tissue planes .\n\nin regional anesthesia is the addition of hyaluronidase is associated with benefits such as faster onest of action and impoved block quality ,however ,evidence regarding its efficacy in peribulbar techniques remains inconsistent.\n\nTo improve the quality and duration of the block, various adjuvants have been investigated. Two promising agents are Midazolam, a benzodiazepine with hypothesized peripheral GABA-ergic action, and Cisatracurium, a non-depolarizing neuromuscular blocking agent. Midazolam may enhance sensory block and provide amnesia, while cisatracurium directly induces chemical paralysis of the extraocular muscles. However, a direct comparative study of their efficacy and safety profiles in this context is lacking. This study aims to fill that gap .\n\n90 eligible patients were randomly allocated into three groups using computer-generated random numbers placed in sealed, opaque envelopes.\n\n* Group L (Control): lidocaine 2٪ (4 ml) + Normal Saline (1 ml).\n* Group M (Midazolam): lidocaine 2٪ % (4 ml) + Midazolam (1 mg in 1 ml).\n* Group C (Cisatracurium): lidocaine 2٪ (4 ml) + Cisatracurium (0.5 mg in 0.5 ml) + Normal Saline (0.5 ml).\n\nThe total volume of the injectate was standardized to 5 ml for all groups.",[90],"Vitreoretinal Surgery",[92,93],"Ophthalmic anesthesia.","Vitreoretinal surgery,","NOT_YET_RECRUITING","2026-04-06",{"date":97,"type":98},"2026-04-09","ACTUAL",{"date":100,"type":84},"2026-05-01",{"date":102,"type":84},"2026-06-15",{"name":5,"class":6},1]
