Lidocaine Plus Ropivacaine Versus Lidocaine Plus Bupivacaine for Peribulbar Anesthesia by Single Medial Injection

Comparação da qualidade do bloqueio oftálmico periconal com ropivacaína a 1% e 0,75% com punção os pontos infraorbitário lateral e medial da órbita

“…A punção periconal, igualmente às outras técnicas, tem mostrado bons resultados quanto à instalação rápida e qualidade do bloqueio. O ponto de acesso na região caruncular ou canto medial é uma boa alternativa para o bloqueio peribulbar, mesmo como punção única [15][16][17][18] . Ripart e col., utilizando punção única na região caruncular, denominaram a técnica como injeção episcleral ou sub-capsular de Tenon, realizada lateralmente à carúncula na região semilunar da conjuntiva 19 .…”

“…Periconal puncture, as other techniques, has shown to be effective in terms of fast onset and blockade quality. The access site at the medial canthus is a good peribulbar blockade alternative, even as a single puncture [15][16][17][18] . Ripart et al, using a single medial canthus puncture, have named the technique episcleral or sub-Tenon injection, performed laterally to the caruncle at the semilunar region of the conjunctiva 19 .…”

Medial Canthus Single-Injection Peribulbar Anesthesia: A Prospective Randomized Comparison With Classic Double-Injection Peribulbar Anesthesia

“…Indeed in this region, the extraconal space is large and avascular, which reduces the risk of hematoma or intravascular injection. Gillart et al 19 reported a significantly lower percentage of hemorrhage after injection at the caruncle. Moreover, Vohra and Good 20 reported no staphylomas in the nasal equatorial region in the eyes they studied.…”

Comparison of Efficacy of Peribulbar Block With the Combination of 2% Lidocaine and 0.75% Ropivacaine in Comparison With 2% Lidocaine and 0.5% Bupivacaine for Cataract Surgeries

“…They concluded that lidocaine with ropivacaine produces better anaesthesia and similar analgesia when compared to lidocaine with bupivacaine. 17 Corke PJ, Baker J, Cammack R, et al compared 1% ropivacaine and mixture of 2% lignocaine and 0.5% bupivacaine for peribulbar anaesthesia in cataract surgery. They concluded that both the groups had excellent surgical analgesia and akinesia.…”
