Ultrasound-guided radial vein cannulation for general anesthesia in cases with difficult peripheral venous access: a report of two cases.

Background: Despite advancements in ultrasonography, locating peripheral veins for catheter placement remains a challenge in patients with altered anatomy owing to multiple surgeries. Herein, we highlight the potential of using the radial vein as an alternative site for ultrasound-guided peripheral venous catheterization.

Case Presentation: We present two cases of patients with extensive surgical histories, including multiple abdominal surgeries, leading to difficult peripheral venous access.

Ultrasound-guided peripheral nerve blocks for anterior cutaneous nerve entrapment syndrome after robot-assisted gastrectomy: A case report.

Background: Anterior cutaneous nerve entrapment syndrome (ACNES) is a condition manifesting with pain caused by strangulation of the anterior cutaneous branch of the lower intercostal nerves. This case report aims to provide new insight into the selection of peripheral nerve blocks for the ACNES treatment.

Case Summary: A 66-year-old woman manifested ACNES after a robot-assisted distal gastrectomy.

A new and simplified extraoral approach for inferior alveolar nerve block: a cadaveric study and clinical case reports.

Purpose: Inferior alveolar nerve (IAN) and lingual nerve (LN) blocks are commonly performed using the intraoral landmark techniques. However, these methods have a risk of unanticipated nerve and arterial injury or a higher failure rate. We developed a novel extraoral approach for the IAN and LN blocks, the "inferior alveolar nerve block mandibular angle approach (IANB-MA)," using ultrasound guidance.
