Clinical studies have demonstrated the efficacy of pulsed radiofrequency (PRF). PRF energy is delivered to neural structures via specifically designed, percutaneously placed needles to treat some chronic pain states. PRF was introduced as a non-destructive alternative to destructive lesioning produced by continuous radiofrequency (CRF) energy. However, there is an ongoing controversy regarding the potential tissue-destructive effects of PRF used for pain management. ⋯ PRF coagulated egg white at temperatures above 60degrees C in a manner similar to CRF. Monitoring needle tip temperature using the thermode supplied with the needle during PRF and keeping the recorded tip temperature below 60degrees C may minimize unwanted thermal destruction of tissue.

Case Reports Comparative Study
Pulsed radiofrequency of lumbar nerve roots for treatment of chronic inguinal herniorraphy pain.
Inguinal hernia repairs are commonly performed and although not seen in a majority of patients, chronic inguinal pain can be a debilitating state resulting after inguinal hernia repairs. Treatment options exist, including pharmacological and surgical management, but with associated risks and side effects. ⋯ The mechanism of action of pulsed radiofrequency remains unclear. This case study demonstrates the effectiveness of minimally invasive neurodestruction of T12, L1 and L2 nerve roots utilizing Pulse Radiofrequency fields.

Chronic low back pain is a major social, economic, and healthcare issue in the United States. Various techniques are utilized in managing discogenic pain, with or without disc herniation. Percutaneous techniques are rapidly replacing traditional open surgery in operations requiring discectomy, decompression, and fusion. ⋯ The most often stated goal of central nuclear decompression is to lower the pressure in the nucleus and to allow room for the herniated fragment to implode inward. Provocative discography prior to percutaneous lumbar disc decompression is recommended. Percutaneous disc decompression may result in a small number of complications but occasionally, these could be serious.

Comparative Study Controlled Clinical Trial
Quality assurance for interventional pain management procedures.
Over the last decade various guidelines for quality assurance in pain medicine have been published for cancer pain, acute postoperative pain and other pain conditions. However, quality assurance for interventional pain management procedures has yet to be addressed. An interventional pain program should at least evaluate 1) efficacy of pain relief; 2) complication rate; and 3) patient satisfaction. ⋯ The results of the current study indicate that quality assurance of interventional pain management procedures in terms of immediate pain relief following the procedure, low complication rate, and high patient satisfaction can be achieved through application of a quality assurance program.

Comparative Study
A novel approach to transnasal sphenopalatine ganglion injection.
Sphenopalatine ganglion block is used to treat headache and facial pain. There are transnasal, transoral and lateral approaches to establish the blockade. The transnasal application of topical anesthetic is the simplest and most common technique among the three. However, the diffusion of topical anesthetic to the ganglion is unpredictable and the blockade is not durable. ⋯ This method preserves the technical simplicity of the original transnasal approach and includes the predictability and durability of the blockade from needle injection.
