Obstetrical lumbar epidural anesthesia in patients with previous posterior spinal fusion for kyphoscoliosis.

Lumbar epidural anesthesia (LEA) may be difficult theoretically in patients with previous extensive spinal surgery, not only because it may be technically difficult to accomplish, but also because the spread of local anesthetics might not be complete in the epidural space. Therefore, some anesthesiologists consider previous spinal surgery a relative contraindication to LEA. Recently, sporadic reports have appeared describing the use of LEA in patients with anatomic abnormalities of the spinal column (1). This report describes the use of LEA in three patients who have had extensive spinal surgery for idiopathic kyphoscoliosis.
