Ultrasound a New Paradigm in Regional Anesthesia and Pain Management

Implication for health policy/practice/research/medical education We have an important mission in this way and have tried to improve the ultrasound knowledge and to continue its attempt. which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. To perform nerve block accurately; imaging to increase safety and maintaining the whole integrity is essential. In the early twentieth century, paresthesia was used to detect the correct location of the nerve but was gradually replaced by more secure methods such as nerve locators and nerve stimulators. During recent years, extremely attention has been focused on nerve stimulation in the regional anesthesia and pain management field but it has a passion for attending all the experts in this field of practice. Perhaps it was due to different individuals and different diseases which cause the nervous stimulation limits. Diseases such as diabetic associated neuropathy can make the nerve stimulator almost worthless. Other neuropathic conditions such as toxic neuropathies, de-myelinating conditions, even peripheral vascular and advanced age can fade the response to the nerve stimula-tor. Placement of the electrode with poor return and inconsistent contact in the active electrode can further take dawn the issues. During the 1980, the idea of using ultrasound as a safe guide in the field of regional anesthesia was proposed. This equipment has the capability of real time dynamic evaluation of the tissues while is showing live image. On the other hand, lack of radiologic exposure danger, comfort ability and low cost of its usage makes this device an acceptable option for the majority of anesthesiologists and pain physicians. The machine itself is more affordable than a fluoroscope, computed tomography scan, or magnetic resonance imaging machine. These characteristic and continued improvements in image quality and resolution have expanded the use of ultrasound in many areas in medicine beyond traditional diagnostic imaging applications. Nowadays by coming ultrasound machines in the more anesthesia wards a new revolution has been started in the field of regional anesthesia and pain management ; while as an increasing willingness toward performing different ultrasound guided nerve blocks has grown up. Actually, Ultrasound imaging has become a popular technique to perform regional anesthesia and pain procedures (1-3). The ability to view and track needles during performing ultrasound nerve blocks is one of the indicators that is considered proficient in working with ultrasound. Other indicators include familiarity in operation with the machine, properly …
