[Changes in epidural pressure during epidural injection].
To evaluate the change of epidural pressure when local anesthetic was injected into epidural space, we inserted three epidural catheters in 13 patients. Epidural catheters were inserted at Th8/9, Th10/11 and L3/4 intervertebral spaces, and 2% mepivacaine 10 ml was injected through Th10/11 or L3/4 catheter. The change of epidural pressure was recorded from three catheters. The elevation of pressure was largest in the injected catheter, but the pattern of elevation was similar in all three catheters. The results suggest that the elevation of epidural pressure occurs at the same time all over the epidural space when local anesthetic is injected.
