Observational Study
Efficacy of Cervical Facet Joint Radiofrequency Ablation Using a Multitined Cannula, a Technical Note, and Observational Study.
Chronic cervical facet joint pain is a leading cause of pain and disability. In patients nonresponsive to conservative treatment, cervical facet radiofrequency ablation (RFA) has shown to be efficacious. However, the conventional RFA technique can be cumbersome. A novel RFA technique with a multitined cannula allows for a lateral approach and represents an attractive alternative option for cervical facet RFA. It offers a potentially shorter, less cumbersome procedure, with consequently less x-ray exposure and patient discomfort than the conventional cervical RFA. ⋯ Our results suggest that cervical facet joint RFA using the novel technique with the multitined cannula results in significant pain reduction and improvement on the PGIC. While the conventional technique requires multiple ablations at each target level, the RFA with the multitined needle requires only a singular ablation, likely sparing time, radiation dose, discomfort, and costs. Our results merit consideration of replacement of the conventional technique with the novel technique using the multitined cannula. However, larger-scale clinical trials with an adequate long-term follow-up period are needed to prove the efficacy of RFA using the multitined cannula in cervical facet joint pain.

ReviewPerfusion index for early identification of regional anesthesia effectiveness: a narrative review.
Regional anesthesia (RA) is a common and irreplaceable technique in clinical, which can be used in different surgery sites and control of acute and chronic pain, especially for outpatients, pediatrics and the elderly. RA demands are increasing during COVID-19 pandemic because many surgeries could be performed under RA to reduce the risk of cross-infection between patients and health care workers. Early and accurate identification of the effects of RA can help physicians make timely decisions about whether to supplement analgesics or switch to general anesthesia, which will save time and improve patient satisfaction in a busy operating room. ⋯ Recently, many studies have assessed the accuracy of PI in early prediction of RA success, including brachial plexus block, sciatic nerve block, neuraxial anesthesia, paravertebral block, caudal block and stellate ganglion block. Successful RA often parallels increased PI. In this narrative review, we describe the principles and influencing factors of PI, and introduce the effects of PI on early identification of RA effectiveness.

Neurologists in both the inpatient and outpatient settings are increasingly using ultrasound to diagnose and manage common neurological diseases. Advantages include cost-effectiveness, the lack of exposure to ionizing radiation, and the ability to perform at the bedside to provide real-time data. There is a growing body of literature that supports using ultrasonography to improve diagnostic accuracy and aid in performing procedures. ⋯ This includes neuromuscular diseases such as motor neuron disorders, focal neuropathies, and muscular dystrophy as well as vascular conditions such as stroke and vasospasm in subarachnoid hemorrhage. We also address ultrasound's use in critically ill patients to aid in identifying increased intracranial pressure, hemodynamics, and arterial and/or venous catheterization. Finally, we address the importance of standardized ultrasound curricula in trainee education and make recommendations for the future directions of research and competency guidelines within our specialty.

Case ReportsGenicular nerve and fracture site chemical neurolysis for distal femoral fracture: a case report.
Distal femur fractures account for approximately 3%-6% of all femoral fractures. Non-operative management may be an attractive option for the elderly with significant perioperative mortality risk. Adequate pain control is a major barrier to non-operative fracture management. Chemical neurolysis has been described for analgesic management of proximal hip fractures, however no description of interventional management of distal femur fracture exists in literature. We describe a case of phenol chemical neurolysis of genicular nerves in addition to injection at the site of fracture to provide effective analgesia for distal femur fracture. ⋯ We report the successful use of phenol neurolysis of genicular nerves and the fracture site in an elderly patient with a conservatively managed distal femur fracture. These interventions resulted in improved analgesia and achieved prolonged duration of effect.
