Until now, no matrix transducer has been realized for 3D transesophageal echocardiography (TEE) in pediatric patients. In 3D TEE with a matrix transducer, the biggest challenges are to connect a large number of elements to a standard ultrasound system, and to achieve a high volume rate (>200 Hz). To address these issues, we have recently developed a prototype miniaturized matrix transducer for pediatric patients with micro-beamforming and a small central transmitter. In this paper we propose two multiline parallel 3D beamforming techniques (µBF25 and µBF169) using the micro-beamformed datasets from 25 and 169 transmit events to achieve volume rates of 300 Hz and 44 Hz, respectively...

BACKGROUND: Trigger finger is a common clinical disorder, characterised by pain and catching as the patient flexes and extends digits because of disproportion between the diameter of flexor tendons and the A1 pulley. The treatment approach may include non-surgical or surgical treatments. Currently there is no consensus about the best surgical treatment approach (open, percutaneous or endoscopic approaches). OBJECTIVES: To evaluate the effectiveness and safety of different methods of surgical treatment for trigger finger (open, percutaneous or endoscopic approaches) in adults at any stage of the disease...

Background: Central venous catheters are inserted ubiquitously in critical care and have roles in drug administration, fluid management and renal replacement therapy. They are also associated with numerous complications. The true number of central venous catheters inserted per year and the proportion of them associated with complications are unknown in the UK. Methods: We performed a prospective audit at five hospitals, as a feasibility pilot for a larger, nationwide audit...

It has been shown that low frequency ultrasound in the presence of microbubble can effectively open the blood brain barrier (BBB) to allow the drugs to be delivered into the brain with an increased concentration. We aim to apply this method to increase the efficacy of Cytarabine (Ara-c) to treat central nervous system leukemia (CNSL). In the present study, we validated this ultrasound contrast agent Sonovue® targeting treatment via in vivo and in vitro experiments. The results showed that Sonovue® combined with Cytarabine could significantly inhibit K562 cell (chronic myeloid leukemia cell line) proliferation...

Spreading beyond the realm of tertiary academic medical centers, point-of-care ultrasound in the intensive care unit is an important diagnostic tool. The real-time feedback garnered can lead to critical and clinically relevant changes in management and decrease potential complications. Bedside ultrasound evaluation in the intensive care setting with a small, portable equipment is well-suited for placement of central lines, lumbar puncture, thoracentesis or other bedside ICU procedures and in the evaluation of cardiac activity, pleural and abdominal cavity and the overall fluid volume...

Central catheters are known as "life lines" in intensive care units and are used frequently in neonatal intensive care unit (NICU) for multiple indications. The central catheters used in NICU includes umbilical venous catheter (UVC), umbilical arterial catheter (UAC) and peripherally inserted central catheter (PICC) lines. The tip of these central lines need to be in correct position as malpositioned central line tips leads to many neonatal complications. Radiograph either abdomen or chest is the most widely used modality for locating the tip of central catheter...

Placement of a central venous catheter (CVC) in the brachiocephalic vein (BCV) via the ultrasound (US)-guided supraclavicular approach was recently described in children. We aimed to determine the CVC maintenance-related complications at this site compared to the others (i.e., the femoral, the subclavian, and the jugular). We performed a retrospective data collection of prospectively registered data on CVC in young children hospitalized in a pediatric intensive care unit (PICU) during a 4-year period (May 2011 to May 2015)...

BACKGROUND: Major health care agencies recommend real-time ultrasound (RTUS) guidance during insertion of percutaneous central venous catheters (CVC) based on studies in which CVCs were placed by non-surgeons. We conducted a meta-analysis to compare outcomes for surgeon-performed RTUS-guided CVC insertion versus traditional landmark technique. METHODS: A systematic review of the literature was performed identifying randomized controlled trials (RCT) and prospective "safety studies" of surgeon-performed CVC insertions comparing landmark to RTUS techniques...

PURPOSE: The traditional technique of placing a peripheral intravenous (IV) catheter is successful in most cases on inpatient wards. However, when the traditional method fails, a central venous catheter may be placed to maintain IV access. These catheters are associated with risks including central line-associated bloodstream infection. METHODS: We evaluated the effectiveness and acceptability of an ultrasound-guided peripheral IV service to reduce the number of newly placed central venous catheters on an inpatient ward...

: Insertion of peripheral iv catheters is a common practice in medical-surgical care settings. The frequency with which attempts are made to insert catheters causes rapid peripheral vessel depletion (a reduction in the number of usable veins), leading to the overuse of unnecessary central line catheters. Reducing central line-associated bloodstream infections is a national health care priority. In this quality improvement report, the authors describe the implementation of a nurse-led vascular access preservation program using ultrasound technology as a method to reduce the use of nonessential peripherally inserted central catheters...

Permanent central venous access is essential for the management of many pediatric patients. Knowing the amount of ionizing radiation used during the insertion of these devices is important. Our aim was to identify the radiation used in percutaneous insertion of central venous access devices, and to correlate radiation exposure to patient weight. METHODS: Data was prospectively collected during a 12-month period from August 2015 to August 2016 on all ultrasound-guided percutaneous central venous access device insertions...

There are many complications of central venous catheter insertion. Iatrogenic injury of the vertebral artery is a rare complication that can result in severe morbidity and mortality. The case presented describes the complication of an acute ischaemic stroke after cannulation of the vertebral artery. There are various techniques when obtaining central access, however the best practice as described by the evidence based guidelines produced by the American Society of Anesthesiologists utilises real-time ultrasound guidance to minimise adverse events...

Ultrasonography is the first choice of lymph node metastasis (LNM) detection which is crucial for therapeutic options of papillary thyroid cancer (PTC). However, the sensitivity of ultrasonography in detecting LNM of PTC is relatively low; especially in central LNM. MiR-324-5p has been reported to play important roles in the metastasis of various cancers. To explore the relationship between miR-324-5p and LNM in PTC, quantitative real-time polymerase chain reaction was performed in PTC tissue and fine needle aspiration (FNA) washout successively...

Ultrasound is a user-dependent tool that can help guide therapy. The use of ultrasound to guide central line placement decreases complication rates. Cardiac ultrasound can help with the diagnosis of cases of hypotension. Lung and pleura ultrasound is a useful adjunct for diagnosis causes of desaturation. Abdominal ultrasound can help in rapid visitation of fluid and intra-abdominal structures.

Recent interest in intracranial pressure (ICP) in the upright posture has revealed that the mechanisms regulating postural changes in ICP are not fully understood. We have suggested an explanatory model where the postural changes in ICP depend on well-established hydrostatic effects in the venous system and where these effects are interrupted by collapse of the internal jugular veins (IJVs) in more upright positions. The aim of this study was to investigate this relationship by simultaneous invasive measurements of ICP, venous pressure and IJV collapse in healthy volunteers...
