T1 Erector Spinae Plane Block Catheter As a Novel Treatment Modality for Pancoast Tumor Pain.

Pancoast tumors are non-small cell lung tumors, which can invade the ribs, vertebrae, sympathetic ganglia and brachial plexus. In this study, a patient with right-sided Pancoast tumor presented with intractable chronic pain on the right neck, upper extremity and chest wall. The chronic pain associated with Pancoast tumor, which was difficult to treat with opioids and other medications, was effectively treated with a high-thoracic erector spinae plane block (ESPB).

A Summary of the Anatomy and Current Regional Anesthesia Practices for Postoperative Pain Management in Total Knee Arthroplasty.

The planning and implementation of an effective postoperative pain management program depend on the surgical technique for total knee arthroplasty (TKA), the type of regional anesthesia, and the multimodal analgesia regimen. It is imperative to understand the surgical anatomy of TKA and the relevant nerve supply of the knee for optimum perioperative patient satisfaction with respect to pain management in the patient undergoing TKA. The commonly used regional techniques have their own specific benefits and limitations.

Effect of body mass index on angle of needle insertion during ultrasound-guided lateral sagittal infraclavicular brachial plexus block.

Study Objectives: The aim of our study was to establish the angle of needle insertion from the anterior chest wall during ultrasound-guided infraclavicular brachial plexus block and to examine for any correlation between body mass index (BMI) and insertion angle.

Design: This is a prospective observational study.

Setting: The setting is at an operating room, university-affiliated teaching hospital.
