Vitamin C and mannitol were found to be effective in reducing ischaemia-reperfusion injury of the ovary during its early stages, but verapamil was ineffective.
Background and Purpose:Today no method of topical anesthesia for intravitreal injection administration has been proven to make the patient comfortable yet. We compared the efficacy of topical levobupivacaine 0.75% and proparacaine 0.5% in patients undergoing intravitreal injections.Materials and Methods:A prospective, randomized study comparing two agents for topical anesthesia in intravitreal injections. Ninety-six consecutive patients were enrolled into two groups to receive either topical levobupivacaine 0.75% (n=48) or proparacaine 0.5% (n=48). Patients were asked to score their pain using a visual analog scale (VAS) immediately following the injection. The average of these scores was used as the primary outcome. The surgeon performing the procedure scored his perception of the patients’ pain using the Wong-Baker FACES scale.Results:Mean VAS pain scores for two groups were found to be 44.77 ± 16.42 and 34.18 ± 14.83, respectively. Mean VAS pain score in the proparacaine group was significantly lower than that in the levobupivacaine group (P= 0.003). Mean Wong-Baker FACES scores for the two groups were 1.08 ± 0.49 and 1.10 ± 0.30, respectively. There was no statistically significant difference between levobupivacaine and proparacaine groups (P=0.824).Conclusions:Topical proparacaine 0.5% was more effective in preventing pain during intravitreal injections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
