Progress of ultrasound-guided nerve block in foot and ankle arthroscopy

Foot and ankle arthroscopy frequently results in severe perioperative swelling and pain. The ultrasound-guided nerve block technique stands out for its ability to offer reliable and potent pain relief. This technique not only promotes early functional exercise, but also realizes enhanced recovery after surgery, which has demonstrated significant advantages in the realm of foot and ankle arthroscopy. In recent years, blocking techniques targeting different nerve planes have been reported to expand the options available for clinical use. This article primarily describes the current application of foot and ankle arthroscopy, detailing various local nerve blocks under innervation and ultrasound guidance. By doing so, this review intends to provide insights for the selection of clinical anesthesia in foot and ankle arthroscopy.

Applications of the ultrasound-guided nerve block technique for nonanalgesic effects.

The nerve block technique guided by ultrasound has been able to accurately block tiny nerves throughout the body in recent years. It has been increasingly used to treat multisystem diseases or analgesia in surgical patients, but the latter accounted for the vast majority of cases. The nonanalgesic effect of nerve blocks is also in wide demand. After searching ultrasound-guided nerve block works on the PubMed database, we systematically summarized the current clinical application of the nerve block technique and the unique role and related mechanism of nerve block in the prevention and treatment of multi-system diseases or symptoms, including disorders of the circulatory and respiratory systems, postoperative cognitive dysfunction, immune function, posttraumatic stress disorder, and postoperative digestive system, to put forward the potential prospective application in future and serve as a reference for future research of nerve block therapy in these diseases mentioned.

Ultrasound-guided femoro–sciatic nerve block with and without using nerve locator for below-knee surgeries

Background Femoral and sciatic nerve blocks is a suitable technique for below-knee surgeries compared with neuroaxial and general anesthetic techniques. Objectives To evaluate the efficacy of ultrasound-guided femoral and sciatic nerve blocks with and without using a nerve locator in below-knee surgeries. Patients and methods Between May 2017 and May 2018, we conducted our randomized, observer-blinded prospective clinical study. Sixty patients underwent below-knee surgeries in Menoufia University Hospitals were involved and divided into two groups of 30 patients each. The groups were assigned into two: group A received ultrasound-guided femoral and sciatic nerve block and in group B, nerve block was done using combined ultrasound with a nerve locator. Results The onset time of motor block was significantly shorter in the nerve locator group than in the ultrasound-only group (P Conclusion Adding nerve locator to the ultrasound-guided nerve block technique has minimal impact on the efficacy of the technique.

Is it possible to exactly visualize the superior cluneal nerve using ultrasound imaging?

To the Editor: We have taken interest in a recently published study by Nielsen et al .[1][1] They demonstrated a novel ultrasound-guided nerve block technique for anaesthetizing the region supplied...

Randomized trial of ultrasound-guided superior cluneal nerve block

Background and objectivesThe superior cluneal nerves originate from the dorsal rami of primarily the upper lumbar spinal nerves. The nerves cross the iliac spine to innervate the skin and subcutaneous...

The Lateral Femoral Cutaneous Nerve: Description of the Sensory Territory and a Novel Ultrasound-Guided Nerve Block Technique.

Nerve blockade of the lateral femoral cutaneous (LFC) nerve provides some analgesia after hip surgery. However, knowledge is lacking about the extent of the cutaneous area anesthetized by established LFC nerve block techniques, as well as the success rate of anesthetic coverage of various surgical incisions. Nerve block techniques that rely on ultrasonographic identification of the LFC nerve distal to the inguinal ligament can be technically challenging. Furthermore, the branching of the LFC nerve is variable, and it is unknown if proximal LFC nerve branches are anesthetized using the current techniques. The primary aim of this study was to investigate a novel ultrasound-guided LFC nerve block technique based on injection into the fat-filled flat tunnel (FFFT), which is a duplicature of the fascia lata between the sartorius and the tensor fasciae latae muscle, in order to assess the success rate of anesthetizing the proximal LFC nerve branches and covering of the different surgical incisions used for hip surgery. First, a cadaveric study was conducted in order to identify an FFFT injection technique that would provide adequate injectate spread to the proximal LFC nerve branches. Second, a clinical study was conducted in a group of 20 healthy volunteers over 2 consecutive days. On trial day 1, successful complete anesthesia of the LFC nerve was defined by performing a suprainguinal fascia iliaca block bilaterally in each subject. On trial day 2, a triple-blind randomized controlled trial compared the effect of the novel ultrasound-guided LFC nerve block technique for bupivacaine versus placebo. The primary end point was the success rate of anesthesia of the proximal cutaneous area innervated by the LFC nerve for the FFFT injection with bupivacaine versus placebo. Adequate spread of injectate to the proximal LFC nerve branches in cadavers was obtained by injecting 10 mL with dynamic needle-tip tracking in the FFFT. Application of this technique in the randomized controlled trial provided anesthesia of the lateral thigh with a success rate of 95% (95% confidence interval, 73.9%-99.8%) for the active side and 0% for placebo (P < 0.001). The proximal branches were anesthetized with a success rate of 68% (95% confidence interval, 43.4%-87.4%) on the active side. The proximal extent of the anesthetized cutaneous area was on average 7.9 cm distal to the greater trochanter. This novel LFC nerve block technique is easy and quick and reliably produces anesthesia of the lateral thigh. The greater trochanter is rarely included in the area of anesthesia, which reduces the coverage of each specific surgical incision. The success rate of 68% in anesthetizing the proximal nerve branches must be further evaluated by future research.

Application of ultrasound-guided peripheral nerve block technique in standardized training for resident doctors

Mastering peripheral nerve block technique is a basic requirement for residents standardization training. Ultrasound-guided nerve block has broken through the limitation of traditional blind operation, promoted the quality and safety of anesthesia, and improved the quality of the peripheral nerve block teaching. However, the safety of ultrasound-guided nerve block technique must be based on the speci-fication training. In the teaching experience, we have used theoretical study, simulation training and clinical practice to explore a new method for upgrading the quality of resident doctor training.
