“…We used the MultiStim Sensor nerve stimulator from Pajunk GmbH (Geisingen, Germany; Figure ). A major advantage of the stimulator is its controllability, which is adjusted according to the progress of the disease . Acute procedures were carried out with patients in a prone position with a pad placed under the abdomen to achieve a trunk and lower limb angle of 30 degrees, exposing the sacrococcygeal region and anus.…”

Background Sacral nerve stimulation (SNS) has revolutionized the management of certain intractable cases of fecal and urinary incontinence; however, the management of functional anorectal pain (FAP) has been addressed in only a few studies. Objective The aim of this study was to evaluate the treatment effect of SNS in improving FAP symptoms. Methods A total of 120 patients with FAP who had undergone temporary SNS probe placement were investigated at Qianfoshan Hospital between January 2014 and December 2016. Pre‐ and post‐SNS treatment outcomes were assessed using the VAS, anorectal manometry, and the 36‐item short‐form health survey (SF‐36) medical outcomes study instrument. Results A total of 120 patients proceeded to insertion of an SNS probe at the S3 nerve root (2 Hz, 1.50 mA, 0.10 milliseconds). Of these, 75 patients were cured, 41 improved, and 4 had an ineffective outcome. The total effectiveness rate was 96.7% 1 year after treatment. There was a significant reduction in the median VAS score pre‐SNS and post‐SNS, from 8 to 3, respectively. Patients post‐SNS had lower anal maximum contraction pressure and anal rest pressure than did patients pre‐SNS. Compared with the pretreatment group, there were no substantial differences between anal longest contraction time and rectal rest pressure. In addition to general health, there was a substantial improvement in the remaining dimension scores of the SF‐36. Conclusion The effect of SNS in treating FAP was positive, and the improvement of symptoms was substantial and worthy of clinical promotion.

“…25 Despite contemporary designs and modern circuitry, nerve stimulators vary in clinical performance. 20,21,23 Barthram 21 demonstrated current output inaccuracies over varying resistance loads among different nerve stimulators used for peripheral nerve blockade. Only 3 of 6 nerve stimulators delivered a target current of 0.3 to 3.0 mA with T20% accuracy.…”

Peripheral nerve stimulation has a long history in regional anesthesia. Despite the advent of ultrasound-guided peripheral nerve blockade, nerve stimulation remains a popular technique used alone or, now, in combination with ultrasound-guided techniques. In light of this evolving utility of nerve stimulation, this is an appropriate time to review the basic concepts and knowledge base of this historically important tool. Electrical nerve stimulation facilitates nerve localization, using threshold current as a surrogate for needle-to-nerve distance. Preferential activation of motor nerves is possible because motor nerve fibers are more readily activated with a shorter duration of current compared with sensory nerves. The association between current and needle-to-nerve distance predicts that less current is needed to evoke a motor response as the needle moves closer to the nerve. Thus, an elicited motor response at or below 0.5 mA is considered a common end point for successful neural blockade. However, current magnitude is neither 100% sensitive nor specific. Independent of technical ability, both the biological environment and the equipment used impact the current-distance relationship. Thus, successful electrical nerve stimulation is dependent on an anesthesiologist with a solid foundation in anatomy and a thorough understanding of electrophysiology.

“…Premier modern nerve stimulators are designed and programmed to guarantee extremely high accuracy for nerve localization. Jochum et al published an objective assessment of widely available peripheral nerve stimulators that are presently marketed (Jochum et al, 2006). Objective scores were assigned, with those having the most accuracy and desirable characteristics achieving the highest evaluations.…”

Electrical nerve stimulation (ENS) is a proven modality for ascertaining close needle‐to‐nerve proximity. ENS has been used for decades and has been associated with high success rates and extremely low complication rates. Ultrasonographic (U/S) guidance has been used increasingly to assist in the placement of peripheral and plexus nerve blocks. U/S guidance allows for real‐time imaging of the needle, targeted nerve or nerves, and other relevant anatomical structures that are in close proximity. Each modality alone has distinct advantages as well as limitations. Each can be used alone for many regional blocks or the two can be combined, more optimally, to take advantage of the positive attributes of both techniques. Both ultrasonographic imaging equipment and techniques devices used for electrical nerve stimulation continue to evolve, improving success and user friendliness.
