Purpose Of Review: Regional anesthesia has experienced a tremendous renaissance of interest over the past several years. Much of this renewed enthusiasm among clinicians is due to the increased usage of ultrasound guidance for peripheral-nerve blocks. This review serves as a useful foundation for the most commonly employed ultrasound-guided blocks utilized by the clinician.
Recent Findings: With recent advances in both sonographic capability and access for anesthesia providers, many peripheral-nerve blocks have become quite amenable to being placed with ultrasound guidance. In addition, the subspecialty of ultrasound-guided regional anesthesia is being further pioneered via both anatomical and pharmacological studies.
Summary: With ultrasound guidance, the regional anesthesiologist has yet another tool to enhance both the accuracy and success of peripheral-nerve blockade. This article serves to display the most clinically relevant nerve blocks utilized in the perioperative setting. It is meant to be used as a clinical starting point for the development of regional anesthesia skills.

Ultrasound-Guided Stellate Ganglion Block Combined with Pharmacological Treatment for Rosacea: A Report of Two Cases.

Rosacea is a chronic inflammatory disease primarily affecting the central facial region, significantly involving the facial blood vessels and the sebaceous gland units associated with hair follicles. The stellate ganglion block (SGB) technique can restore balance to autonomic nervous function by interrupting the impulse conduction of preganglionic and postganglionic sympathetic nerve fibers, thereby alleviating excessive peripheral blood vessel contraction, enhancing tissue blood supply, balancing hormone secretion, and modulating immune responses. SGB has demonstrated remarkable efficacy in treating various skin conditions affecting the head, face, and neck.

Background: Lung cancer surgery is associated with a high incidence of chronic postsurgical pain (CPSP), which necessitates long-term analgesic prescriptions. However, while essential for managing pain, these have shown various adverse effects. Current guidelines recommend using peripheral nerve blocks over epidural anaesthesia for perioperative analgesia in minimally invasive thoracic surgery (MITS).

This study investigated the impact of multiple nerve block methods (local anesthesia, conventional radiofrequency thermocoagulation [CRF], and pulsed radiofrequency [PRF]) on thermoregulation. Focusing on hypothalamic function, the effects of local anesthesia, CRF, and PRF on central and peripheral temperatures were analyzed and compared. Our findings revealed that all three nerve block groups cause a decrease in central temperature, with the CRF group exhibiting the most pronounced effect.

Clonus is characterized by involuntary, rhythmic, oscillatory muscle contractions, typically triggered by rapid muscle stretching and is frequently associated with spastic equinovarus foot (SEVF), where it may increase risk of falls and cause discomfort, pain, and sleep disorders. We hypothesize that selective diagnostic nerve block (DNB) of the tibial nerve motor branches can help identify which muscle is primarily responsible for clonus in patients with SEVF and provide useful information for botulinum neurotoxin type A (BoNT-A) treatment. This retrospective study explored which calf muscles contributed to clonus in 91 patients with SEFV after stroke (n = 31), multiple sclerosis (n = 21), and cerebral palsy (n = 39), using selective DNB.

Background: Traumatic rib fractures are associated with pain lasting weeks to months and a decreased ability to inspire deeply or cough to clear secretions. Ultrasound-guided percutaneous cryoneurolysis involves reversibly ablating peripheral nerve(s) using exceptionally low temperature with a transdermal probe, resulting in a prolonged nerve block with a duration measured in months. We hypothesized that cryoneurolysis would improve analgesia and inspired volume following rib fracture.
