Kilohertz high-frequency alternating current (KHFAC) electrical nerve stimulation produces a reversible nerve block in peripheral nerves in human patients with chronic pain pathologies. Although this stimulation methodology has been verified with nonselective extrafascicular electrodes, the effectiveness of producing a selective nerve block with more-selective intrafascicular electrodes has not been well documented. The objective of this study was to examine whether intrafascicular electrodes can block painful stimuli while preserving conduction of other neural activity within the implanted nerve. ⋯ KHFAC stimulation in peripheral nerves through intrafascicular electrodes demonstrated a selective reduction in pain sensitivity while preserving other nerve functions. This treatment may benefit patient populations who have chronic pain originating from peripheral nerves, but who do not want to block whole-nerve function in order to preserve sensory and motor function reliant on the implanted nerve. Furthermore, KHFAC may benefit patients who respond negatively to other forms of peripheral nerve stimulation therapy.

Randomized Controlled TrialAdditional benefit of local infiltration of analgesia to femoral nerve block in total knee arthroplasty: double-blind randomized control study.
Multimodal analgesia has become an important concept in current pain management following total knee arthroplasty (TKA). However, controversy remains over what is the most accepted combination. In this study, the additional benefits of local infiltration of analgesia to femoral nerve block were evaluated. ⋯ Randomized controlled trial, Level I.

ReviewGetting to know a familiar face: Current and emerging focused ultrasound applications for the perioperative setting.
Ultrasound technology is available in many pediatric perioperative settings. There is an increasing number of ultrasound applications for anesthesiologists which may enhance clinical performance, procedural safety, and patient outcomes. This review highlights the literature and experience supporting focused ultrasound applications in the pediatric perioperative setting across varied disciplines including anesthesiology. The review also suggests strategies for building educational and infrastructural systems to translate this technology into clinical practice.

Randomized Controlled Trial Comparative StudyUltrasound-Guided Serratus Plane Block Versus Erector Spinae Block for Postoperative Analgesia After Video-Assisted Thoracoscopy: A Pilot Randomized Controlled Trial.
There is no gold standard for the management of postoperative pain after video-assisted thoracoscopic surgery (VATS). Interfascial nerve blocks were proposed as simple and effective options. ⋯ ESB provided superior analgesia and longer time to first required analgesic than did SPB.

The erector spinae plane block for effective analgesia after lung lobectomy: Three cases report.
The thoracic epidural block and thoracic paravertebral block are widely used techniques for multimodal analgesia after thoracic surgery. However, they have several adverse effects, and are not technically easy. Recently, the erector spinae plane block (ESPB), an injected local anesthetic deep to the erector spinae muscle, is a relatively simple and safe technique. ⋯ Our contrast imaging data provides valuable information about mechanism of ESPB from a living patient, and our report shows that ESPB can be a good option as a multimodal analgesia after lung lobectomy.
