Although there is insensitivity to pain, some patients present tactile hyperesthesia that can cause unpleasant feelings during surgical manipulation. Despite reports in the literature of patients undergoing neuroaxis blocks, and even procedures without anesthesia, intravenous anesthesia, which provided adequate conditions for the anesthetic-surgical procedure was used in this case.

The use of bupivacaine (S75-R25) and ropivacaine in labor analgesia provided good conditions for spinal anesthesia with small indices of adverse events.

Summary: Nogueira CS, Lima LC, Paris VC, Neiva PM, Otani ET, Couceiro RO, Burim F, Ferreira Junior JAF, Cadecaro P -A Comparative Study between Bupivacaine (S75-R25) and Ropivacaine in Spinal Anesthesia for Labor Analgesia. Background and objectives:Spinal anesthesia is used for relief of pain during labor and it is associated with low indices of complications. Studies with levorotatory enantiomers of local anesthetics demonstrate higher safety due to the lower cardiotoxicity. The objective of this study was to evaluate the latency and duration of analgesia and maternal and fetal repercussions with bupivacaine (S75-R25) and ropivacaine in spinal anesthesia for labor analgesia.
