“…It should be mentioned that the first request of a rescue dose in this group was made later (67.08 min) than in the other two. In order to evaluate the quality of the block and maternal-fetal repercussions of the epidural administration of 0.5% bupivacaine, 0.5% enantiomeric excess mixture (S75-R25) or 0.75% ropivacaine associated with fentanyl in pregnant women undergoing cesarean sections, Cortes et al 16 did not observe any differences among the study groups except for the quality of the block, which was clinically inferior in the groups with a predominance of the levorotatory form, with a need to complement the analgesia in three cases. In the present study, the quality of analgesia was superior in the group who received a greater concentration of the enantiomeric excess solution.…”

“…Vale ressaltar que a solicitação da primeira dose-resgate nesse grupo foi mais retardada (67,08 min) e este era o grupo que utilizava a maior concentração de anestésico local. Com o objetivo de avaliar a qualidade da anestesia e as repercussões materno-fetais com o emprego de bupivacaína a 0,5%, da mistura enantiomérica da bupivacaína (S75-R25) a 0,5% ou da ropivacaína a 0,75%, associadas ao fentanil por via peridural em gestantes submetidas a cesarianas, Cortes e col. 16 observaram que não houve diferença entre os grupos, exceto na qualidade da anestesia que foi inferior sob o aspecto clínico nos grupos com predominância da fração levógira, havendo necessidade de complementação da anestesia em três casos. No presente estudo, a qualidade da analgesia foi superior no grupo que utilizou o anestésico local com maior fração levógira e com uma concentração mais elevada.…”

“…Aadministração de S75-R25 em camundongos potencializou a intensidade e prolongou o tempo de analgesia quando comparada à S50-R50, especialmente nas menores concentrações (0,125% e 0,25%). A literatura relata que a S75-R25 proporciona boas condições para a realização do ato anestésico-cirúrgico com adequados bloqueios motor e sensorial [22][23] prolongando a analgesia pós-operatória em relação à S50-R50 24 . Além disso, a S75-R25 mostrou-se formulação mais segura que a S50-R50 água, facilitando o acesso de anestésicos hidrofóbicos, como S50-R50 e S75-R25, ao local de ação.…”

“…The literature has demonstrated that the administration of epidural bupivacaine (S75-R25) is associated with lower intensity of motor blockade 8,9 , besides preserving the differential blockade of racemic bupivacaine, representing an advantage of its use in labor analgesia 10,11,12,13 . Parturientss who participated in this study received 0.25% bupivacaine (S75-R25) and 0.20% ropivacaine.…”
