Chronic Pain-Definition An unpleasant sensory & emotional experience associated with actual tissue damage or described in terms of such damage. (IASP) Pain that persists 6 months after an injury, and beyond the usual course of acute disease, that is associated with chronic pathological process and may not be amenable for routine pain control methods, and healing may never occur (ASIPP) 7/20/2013
Interventional Pain Management-Definition The discipline of medicine devoted to the diagnosis and treatment of pain and related disorders by the application of interventional techniques in managing sub-acute, chronic, persistent, and intractable pain, independently or in conjunction with other modalities of treatments.(NUCC) (National Uniform Claims Committee) 7/20/2013
Interventional Techniques- Definition Minimally invasive procedures, such as needle placement of drugs in targeted areas, ablation of targeted nerves, and some surgical techniques, such as discectomy and the implantation of intrathecal infusion pumps and spinal cord stimulators. (MedPAC) (Medicare Payment Advisory Commission) 7/20/2013
Evidence-based Medicine EBM is defined as a conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The following lecture is prepared based on Evidence-Based Guidelines for Interventional Techniques in Chronic Spinal Pain by ASIPP Pain Physician 2013, (16), S1-S48. ISBN 1533-31 7/20/2013

Moderate evidence for Transforaminal-ESI for short and long-term pain relief. 7/20/2013

Disc-related pathology: Percutaneous Epidural Adhesiolysis Racz Epidural catheter Removal of epidural Fibrosis 7/20/2013 Indication: epidural Fibrosis (Scar tissue) causing Low back pain with radiculopathy Technique: Inject dye caudally, demonstrate filling defects, insert EpimedRacz catheter, steer and twist tip in circles, inject Hyaluronidase (1500 U in 10ml NS), inject local anesthetic and steroid. Followed by neural flossing exercises. Complications: spinal cord compression from loculation of the injected fluid Outcome: FBSS pts showed a reduction in pain and improvement in functional status in 73% of the epidural adhesiolysisgp compared to 12% in the control gp.

Disc-related pathology: Discogenic Pain (diagnostic) Pressure controlled Discography Disc pathology 7/20/2013 Indications: Other pain generators have been ruled, considering surgery or p/c interventions. Surgery is planned, and the surgeon desires an assessment of the adjacent disc levels. Technique: pressure controlled discography with manometer (Discpoint) syringe and contrast medium.
Discogenic Pain – Diagnostic-Provocation Discography Positive Response 7/20/2013 Positive response is: pain ≥7/10 at pressure <50 psi , concordant pain, grade 3 or greater annular tear, ≤ 3.5 mL volume, and at least one negative control disc. Complications: Discitis, < 0.15% per patient, diminished with the double- vs. single-needle technique, screening for infection, aseptic skin preparation, styleted needles, and IV and antibiotics
