Effect of epidural corticosteroid injection on magnetic resonance imaging findings.

Background: Magnetic resonance imaging (MRI) of the spine is the preferred diagnostic tool for pathologic conditions affecting the spine. However, in patients receiving epidural corticosteroid injection (ESI) for treatment of spinal diseases, there is a possibility of misreading of MR images because of air or fluid in the epidural space after the injection. Therefore, we defined the characteristics of abnormal changes in MRI findings following an ESI in patients with low back pain.

A Comparison of Oxycodone and Alfentanil in Intravenous Patient-Controlled Analgesia with a Time-Scheduled Decremental Infusion after Laparoscopic Cholecystectomy.

. Oxycodone, a semisynthetic opioid, has been widely used for acute and chronic pain. .

Anaphylactic Shock Following Nonionic Contrast Medium during Caudal Epidural Injection.

Caudal epidural injection is a common intervention in patients with low back pain and sciatica. Even though the complications of fluoroscopically directed epidural injections are less frequent than in blind epidural injections, complications due to contrast media can occur. We report a case of anaphylactic shock immediately after injection of an intravenous nonionic contrast medium (iohexol) during the caudal epidural injection for low back pain and sciatica in a patient without a previous allergic history to ionic contrast media (ioxitalamate).

Intravenous Patient-controlled Analgesia Has a Positive Effect on the Prognosis of Delirium in Patients Undergoing Orthopedic Surgery.

Background: Postoperative delirium is relatively common. However, the relationship between intravenous patient-controlled analgesia (IV-PCA) and delirium has not been thoroughly investigated. The aim of this study was to evaluate the effects of IV-PCA on the prognosis of postoperative delirium in patients undergoing orthopedic surgery.

Changes in bone mineral density in postmenopausal women treated with epidural steroid injections for lower back pain.

Background: Therapy with corticosteroids often results in bone loss and corticosteroid-induced osteoporosis. In previous studies, bone mineral density (BMD) has been examined after administration of relatively high oral doses of corticosteroids. However, practitioners use comparatively lower doses of corticosteroids for epidural steroid injections (ESI).

The dosages of corticosteroid in transforaminal epidural steroid injections for lumbar radicular pain due to a herniated disc.

Background: Intervertebral disc herniations are the most common cause of lumbosacral radiculopathy, and transforaminal epidural steroid injection (TFESI) is an important tool in treating lumbosacral radiculopathy. But the ideal dose of corticosteroid in the epidural management of lumbosacral radiculopathy has yet to be determined.

Objective: The aim of this study was to determine the effective dose of steroids in TFESI for pain reduction in patients with lumbosacral radiculopathy.
