Needle visualization is important for safe and successful ultrasound-guided peripheral nerve block. However, accurate and consistent visualization of the needle tip can be difficult to achieve. This review article describes many of the challenges affecting needle visualization, summarizes the relevant literature on ultrasound imaging of needles, and offers(More)
OBJECTIVE The purpose of this study was to evaluate the feasibility of sonography in identifying the anatomic structures of the upper airway and to describe their appearance on sonography. METHODS We enrolled 24 healthy volunteers, placed them supine with their head extended and neck flexed (the "sniffing" position), and performed a systematic sonographic(More)
Thoracic neuropathic pain is a debilitating condition that is often poorly responsive to oral and topical pharmacotherapy. The benefit of interventional nerve block procedures is unclear due to a paucity of evidence and the invasiveness of the described techniques. In this report, we describe a novel interfascial plane block, the erector spinae plane (ESP)(More)
A woman with severe ankylosing spondylitis presented to the preanesthetic clinic before total hip arthroplasty. She had required general anesthesia with fiberoptic intubation after failed attempts at spinal anesthesia for previous hip surgery. Using a portable ultrasound unit, we identified an open L4-5 interlaminar space and offered the patient an(More)
The ultrasound-guided transversus abdominis plane (TAP) block is a useful tool in controlling postoperative pain following abdominal surgery. The bilateral ultrasound-guided TAP blocks successfully managed the pain of a patient presenting with hypoxemia and respiratory failure in the Post-anesthesia Care Unit, following a laparotomy for small bowel(More)
PURPOSE Precise localization of the cervicothoracic vertebral levels is essential for accurate placement of epidural catheters. Previous studies have demonstrated that anesthesiologists are inaccurate when using surface anatomy to locate lumbar vertebral levels. Our study was designed to determine the agreement between anatomical landmarks and the(More)
BACKGROUND AND OBJECTIVES Ultrasound-guided (USG) ankle block has been described; however, its clinical efficacy compared with conventional anatomic landmark-guided (ALG) techniques remains undetermined. METHODS We performed a 6-year retrospective cohort study of all ankle blocks performed for foot surgery and extracted demographic, intraoperative, and(More)
BACKGROUND AND OBJECTIVES The Imperial College Surgical Assessment Device (ICSAD) has been validated in various settings as an objective tool to measure technical performance. We sought to establish (1) the construct validity of the ICSAD as an assessment tool in ultrasound-guided supraclavicular block by determining its ability to discriminate between(More)
