Abstract
Two adult patients had lower limb pain and it was difficult to insert a catheter into the epidural space because of their deformities of the spine. An epidural catheter was inserted into the psoas compartment and a local anesthetic was administered via the catheter in each patient.
The injection of 10-20ml of the anesthetic solution produced pain reduction in both of them. No complications were obserbed.
This block could be easily performed by using a nerve stimulator and was advantageous to the patients with pain of a lower extremity.
