Spinal anesthesia for Cesarean delivery following pre-existing epidural labour analgesia.

摘要

To the Editor,We read with interest the retrospective study by Visser et al.reporting the safe use of spinal anesthesia for Cesarean delivery following a pre-existing labour epidural block. The authors attribute a "poorly justified reputation" to a high or total spinal following a pre-existing epidural block. Spinal administration after a suboptimal labour epidural analgesia remains highly controversial,and our information is limited to retrospective studies and case reports.
