This study was designed to assess the accuracy of point-of-care ultrasound in determining the position of double-lumen tubes (DLTs).A total of 103 patients who required DLT intubation were enrolled into the study. After DLTs were tracheal intubated in the supine position, an auscultation researcher and ultrasound researcher were sequentially invited in the operating room to conduct their evaluation of the DLT. After the end of their evaluation, fiberscope researchers (FRs) were invited in the operating room to evaluate the position of DLT using a fiberscope...

Airway management is a critical skill in the practice of several medical specialities including anesthesia, emergency medicine, and critical care. Over the years mounting evidence has showed an increasing role of ultrasound (US) in airway management. The objective of this narrative review is to provide an overview of the indications for point-of-care ultrasound (POCUS) of the upper airway. The use of US to guide and assist clinical airway management has potential benefits for both provider and patient. Ultrasound can be utilized to determine airway size and predict the appropriate diameter of single-lumen endotracheal tubes (ETTs), double-lumen ETTs, and tracheostomy tubes...

Upper airway ultrasound is a valuable, non-invasive, simple, and portable point of care ultrasound (POCUS) for evaluation of airway management even in anatomy distorted by pathology or trauma. Ultrasound enables us to identify important sonoanatomy of the upper airway such as thyroid cartilage, epiglottis, cricoid cartilage, cricothyroid membrane, tracheal cartilages, and esophagus. Understanding this applied sonoanatomy facilitates clinician to use ultrasound in assessment of airway anatomy for difficult intubation, ETT and LMA placement and depth, assessment of airway size, ultrasound-guided invasive procedures such as percutaneous needle cricothyroidotomy and tracheostomy, prediction of postextubation stridor and left double-lumen bronchial tube size, and detecting upper airway pathologies...

INTRODUCTION: Fiberoptic bronchoscopy is the standard method for verifying the correct position of a double-lumen endotracheal tube (DLET) prior to one-lung ventilation. However, it must be performed by a specially trained anesthesiologist and is often resource consuming. The aim of this study was to compare this approach with thoracic ultrasound done by a nurse anesthetist in terms of sensitivity, specificity, and cost-effectiveness. METHODS: We conducted a prospective cross-over case-control study involving 51 adult patients consecutively undergoing thoracic surgery with one-lung ventilation...

BACKGROUND: Sonography has become the imaging technique of choice for guiding intraoperative interventions in abdominal surgery. Due to artefacts from residual air content, however, videothoracoscopic and open intraoperative ultrasound-guided thermoablation of lung malignancies are impossible. Lung flooding is a new method that allows complete ultrasound imaging of lungs and their tumours. METHODS: Fourteen resected tumourous human lung lobes were examined transpleurally with B-mode ultrasound before (in atelectasis) and after lung flooding with isotonic saline solution...

BACKGROUND: We tested the hypothesis that the mouse peritoneum can function like a bioreactor to generate directed bio-engineered tissues such as those used for bypass grafting. Additionally, we reasoned that the mouse animal model would allow us to elucidate the underlying cellular and molecular mechanisms that are responsible for the generation of tissue in peritoneal cavity. METHODS: Plastic tubes (two tubes/mouse) were implanted into the peritoneal cavity of three strains of mice (C57BL/6, BALB/c, and MRL)...

Ultrasound imaging of the upper airway in critically ill patients offers a number of attractive advantages compared with competitive imaging techniques or endoscopy. It is widely available, portable, repeatable, relatively inexpensive, pain-free, and safe. In this review article, I describe ultrasonographic anatomy of the upper respiratory organs and present the main potential applications of ultrasonography in airway management. The role of ultrasound in endotracheal tube placement, including preintubation assessment, verification of tube position, double-lumen intubation, and extubation outcome, are explained...

A 28-year-old woman, 20 weeks pregnant, was diagnosed with aortic coarctation and postcoarctation mycotic aneurysm. After anesthetic induction, blood pressure was monitored in the radial artery of the right arm and the femoral artery of the right leg for two purposes: to verify hemodynamic stability as required in this type of operation and to determine the pressure gradient between the upper and lower limbs, which was approximately 40 mm Hg. To prevent spinal cord ischemia, an intradural catheter was inserted into the fourth and fifth lumbar space for spinal fluid drainage...

OBJECTIVE: Intraluminal thrombosis of the catheter was thought to be a major cause of catheter dysfunction. We evaluated if thrombi appear in the luminal side or outside of the catheters placed in the femoral vein in 21 hemodialysis patients. METHODS: 23 double-lumen catheter (25 cm long and 4 mm diameter polyurethane) strippings were consecutively performed. Mean catheter dwell time was 17.9 +/- 11.2 days (2-45 days). The femoral vein was observed with ultrasound echography, and thrombo-venous ratio (thrombus diameter/vein diameter) was calculated...

A sonographic examination of the lung has so far been impossible because of sound reflection. In conjunction with video-assisted thoracoscopic surgery, lung sonography would be helpful to make up for the lack of direct palpation. Animal experiments with pigs were performed to find out whether lung sonography becomes possible following bronchoalveolar flooding with a suitable liquid. The lung was filled with whole electrolyte solution through the left leg of a double-lumen endotracheal tube after resorption atelectasis (method 1) or compressive atelectasis (method 2)...
