Postamputation pain is challenging because of complex mechanisms involving a multitude of pain pathways and psychological factors. This patient population also tends to have extensive comorbidities with or without a background of chronic pain. Electrical neuromodulation such as peripheral nerve stimulation has gained traction in the realm of chronic pain. Recently, the off-label use of hybrid perineural nerve stimulation in combination with locoregional block via the stimulating nerve block catheter has been described in single-center case reports. ⋯ Our case series supports the feasibility of using a combination of low-frequency perineural stimulation and local anesthetic infusion via a single perineural nerve block catheter to manage challenging postamputation pain.

This study was performed to evaluate trends in and provide future direction for anesthesiology education, research, and clinical practice. ⋯ The current study provides a historical view of high-impact papers in anesthesiology in the past ten years. High-impact papers were mostly from the USA. Postoperative analgesia, chronic pain, and perioperative complications have been hot topics, and COVID-19 became a new topic in 2020. These findings provide references for education, research, and clinical practice in the field of anesthesiology.
