Su J, et al. - Researchers examined their Acute Pain Medicine database for cases in which postoperative epidural analgesia (EA) was used, in order to describe their experience with postoperative EA for oncologic surgery. Postoperative EA was used in 18,895 cases. The identified complications were neurological symptoms in 2436 cases (12.9%), epidural insertion site abnormalities in 1062 cases (5.6%), complete epidural catheter migration in 829 cases (4.4%), epidural replacement in 619 cases (3.3%), and inadvertent dura puncture in 322 cases (1.7%). Persistent deficits of uncertain etiology were noted in 6 cases, deep spinal infections in 4 cases (1:4724), and catheter tip shearing in 2 cases. Although neurological changes were not uncommon, they rarely encountered serious complications resulting in prolonged sequelae.
