Why the study?
Does previous regional analgesia influence the incidence of unblocked segments and unilateral analgesia during lumbar epidural block in labour?
Does previous regional analgesia influence the incidence of unblocked segments and unilateral analgesia during lumbar epidural block in labour?
Previous regional analgesia does not increase the risk of unblocked segments or unilateral analgesia during subsequent lumbar epidural block in labor.
May support repeat neuraxial blocks in labor without added unilateral risk concern; leaves open prospective confirmation.
Two hundred and six patients were studied to discover if previous regional analgesia influenced the incidence of unblocked segments and unilateral analgesia during lumbar epidural block in labour. Previous lumbar epidural or subarachnoid or sacral epidural blocks alone did not appear to influence the incidence of unilateral block or of unblocked segments. The practice of using epidural analgesia to facilitate the insertion of cervical circumsuture during pregnancy did not appear to be contra-indicated.
