double lumen tube ultrasound

Adi Osman, Kok Meng Sum
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...

BACKGROUND: The management of patients with simultaneously diagnosed colorectal liver and lung metastases (SLLM) remains controversial. A recent study based on an analysis of the LiverMetSurvey demonstrated that patients with SLLM suitable for resection of all metastases have a survival similar to that of patients who undergo removal of isolated liver metastases.1 Simultaneous transdiaphragmatic resection of peripheral lung lesions and liver resection by laparotomy has been described previously...

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...

OBJECTIVE: To report our experience with thoracoscopic pericardial window (TPW) for occult penetrating cardiac injury. PATIENTS AND METHODS: During the study period (1 January - 31 December 2000), a small group of haemodynamically stable patients with anterior left-sided praecordial wounds were selected for TPW. All patients underwent general anaesthesia with double-lumen intubation and collapse of the left lung. A rigid laparoscope was inserted through a 2 cm incision in the 5th intercostal space in the anterior axillary line...

OBJECTIVE: Owing to lack of objective measures, the diagnosis of food hypersensitivity may be difficult. The aim of this study was to investigate whether the intestinal response to direct provocation in patients with food hypersensitivity could be recognized by ultrasound. MATERIAL AND METHODS: Thirty-two patients with chronic abdominal complaints, self-attributed to food hypersensitivity/allergy were included in the study. Via a nasoduodenal tube, the duodenal mucosa was challenged with the suspected food item dissolved in 10 ml water or saline...

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...

PURPOSE: We introduce the technique of thoracoscopic transdiaphragmatic adrenalectomy. MATERIALS AND METHODS: Initially in 4 human cadavers bilateral thoracoscopic nephrectomy was performed to develop the technique of diaphragmatic incision, retroperitoneal control of renal artery and vein, circumferential mobilization of the kidney and adrenal gland, and suture repair of the diaphragm. Subsequently, 3 select patients underwent thoracoscopic transdiaphragmatic adrenalectomy (2 right side and 1 left side)...

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)...

BACKGROUND: The preoperative staging of lung cancer can be problematical when we attempt to evaluate T factor (T2-T3 versus T4) and N factor (N0 versus N1-N2). In some cases, radiology tests (CT scan, magnetic resonance imaging) cannot entirely dispel the possibility that the mediastinal structures have been infiltrated. N factor is evaluated mainly by dimensional criteria. However, mediastinoscopy and mediastinotomy do not allow the full exploration of all mediastinal mode stations. METHOD: Starting in 1995, we submitted 10 consecutive patients to videothoracoscopic operative staging with ultrasound color Doppler (VOS-USCD)...

The appearances of hepatic steatosis and of dilated intrahepatic bile ducts occurring independently are well described. When both conditions occur simultaneously a major sign of biliary obstruction, a double lumen with echogenic walls (the double-barrelled shotgun sign), is modified by the abnormally echogenic liver. The combined appearance is of a tubular structure with no echogenic interface with the liver, containing an echogenic structure at its centre representing echoes from the adjacent bile duct and portal vein walls...
