New diagnostic and therapeutic devices for patients with chronic intractable pain are used in Japan. The following articles describe topics of new diagnostic and therapeutic devices for patients with chronic intractable pain including thermography, functional MRI, device for the quantitative analysis of perception and pain sensation, epiduroscopy, device for phototherapy, Racz catheter and device for spinal cord stimulation (SCS).

In recent years, failed back neck surgery syndrome (FBNSS) has been increasing as the number of spinal surgeries rises. In particular, the frequencies of surgeries for intervertebral disk herniation and spinal stenosis are high, and FBNSS is commonly attributable to these procedures. FBNSS is a challenging disease for us pain clinicians, and its causes and treatment methods are diverse. ⋯ In contrast, Racz Spring Guide Catheters epidural neuroplasty can be carried out in outpatient settings, is less invasive and achieves excellent pain relief. Because of the superior performance and handiness of the Racz Spring Guide Catheter instruments, it is a technique that can be carried out in many institutions. This report describes the instruments and operative techniques applied for Racz Spring Guide Catheter epidural neuroplasty.

As scoliosis surgery in children is a large invasive surgery, postoperative pain control is difficult. ⋯ The amount of fentanyl required for postoperative analgesia was decreased by combining DEX. In addition, it is thought that side effects of fentanyl are reduced in low dose fentanyl administration cases. As a result, it may bring early postoperative recovery. The IV-PCA using fentanyl with DEX may be useful for postoperative analgesia in scoliosis surgery. We will recommend using DEX (0.25 microg x kg(-1) x hr(-1)) together with fentanyl (0.5 microg x kg(-1) x hr(-1)) for this purpose.
