Challenges with two epidural catheters for labor analgesia in a patient with lumbar adhesions: a case report

Abstract Background The efficacy of neuraxial analgesia varies with spinal canal pathology. Notably, a secondary epidural catheter has been shown to increase neuraxial labor analgesia in women with spinal lesions. Therefore, we present a case in which catheter withdrawal played a critical role in achieving effective labor analgesia in a woman with epidural adhesions after lumbar discectomy who had inadequate analgesia with two epidural catheters. Case presentation We encountered a patient with L5 lumbar epidural adhesions who reported pain even after receiving two epidural catheters. The catheters were placed in the L1/2 and L5/S intervertebral spaces. Analgesic effects were exerted when the L5/S catheter was withdrawn by 1 cm, suggesting that the catheter tip was initially placed inside the adhesion. Conclusions Careful consideration of catheter placement and adjustments by withdrawing the catheter are crucial in managing labor analgesia in patients with known epidural adhesions.
