Background: Our previous work demonstrating great ease and predictability of cannulation of the major aortic arch branches with an upwardly pointing 3DR catheter, irrespective of aortic arch type, led us to hypothesize that centering or "cresting" of these vessels must occur along the superior most aspect of the aortic arch in a curvilinear fashion. Methods: We retrospectively analyzed 111 computed tomographic scans of the chest and thoracic aorta with intravenous contrast performed at our hospital between April 2011 and May 2012 utilizing TeraRecon image reconstruction software...

Neonatal cardiogenic shock most commonly occurs due to critical congenital heart disease, sepsis, metabolic disorder or arrhythmias. In particular, enterovirus infections are common in the neonatal period, and patients can present with fulminant myocarditis. Early recognition is imperative due to its high morbidity and mortality without prompt and aggressive treatment. We present the successful treatment of fulminant neonatal enteroviral myocarditis in a pair of monochorionic diamniotic twins with cardiopulmonary support, intravenous immunoglobulin and pocapavir, an enteroviral capsid inhibitor...

BACKGROUND: Approximately 1.2 billion peripheral intravenous catheters are inserted across the world annually. It is known that intravenous cannulation may be a painful procedure, which affects cognitive abilities by increasing anxiety and discomfort. AIM: We hypothesized that inserting a smaller sized peripheral intravenous catheter has a lower level of pain sensation compared to a larger sized catheter. METHODS: This observational, cross-sectional study was conducted between May and October 2016, in which surgical patients, aged 18 years or older, were eligible to participate...

Kaurenoic acid (KA) is a kaurane diterpene found in several medicinal plants that displays biological activities, such as anti-inflammatory, smooth muscle relaxant and hypotensive response. However, there are no pharmacokinetic data available about this molecule. The purpose of the study was to determine the pharmacokinetics profile and the oral bioavailability of KA in rats. Wistar rats submitted to jugular vein cannulation received 50 mg/kg of KA by intravenous or oral route. The implanted cannula allowed intravenous administration and serial blood collection along 10 h...

With the removal of bisphenol A (BPA) from many consumer products, the potential use of alternatives such as bisphenol S (BPS) and its derivatives is causing some concerns. These studies investigated the comparative in vitro hepatic clearance and metabolism of BPS and derivatives and the disposition and metabolism of BPS in rats and mice following gavage and intravenous administration. The clearance of BPS and its derivatives was slower in human hepatocytes than in rodents. In male rats following gavage administration of 50, 150, and 500 mg/kg [14 C]BPS the main route of excretion was via urine; the urinary excretion decreased (72 to 48%) and the fecal excretion increased (16 to 30%) with increasing dose...

The cannulation technique used during veno-venous extracorporeal membrane oxygenation (VV ECMO) insertion can have a major impact on a patients' overall outcome. We have developed a technique that aims to combine speed and effectiveness, with minimal risk. The steps include: (I) percutaneous cannulation using the Seldinger technique; (II) ultrasound guided access and positioning of cannulas; (III) femoro-femoral circuit configuration with a later option of high flow; (IV) a no skin cut serial dilation technique; (V) non-suturing securing of cannulas and (VI) a non-surgical manual pressure technique of explantation...

Steers exposed to an endotoxin may require additional branched-chain AA (BCAA) to support an increase in synthesis of immune proteins. This study evaluated effects of bacterial lipopolysaccharide (LPS) and BCAA supplementation on blood metabolites and N balance of 20 ruminally-cannulated steers (177 ± 4.2 kg BW). The experiment was a randomized block design, with 14-d adaptation to metabolism stalls and diet (DM fed = 1.5% BW) and 6-d collection. Treatments were a 2 × 2 factorial of LPS (0 vs 1.0 to 1.5 μg/kg BW; -LPS vs +LPS) and BCAA (0 vs 35 g/d; -BCAA vs +BCAA)...

INTRODUCTION: Minimally invasive cardiac surgery (MICS), via minithoracotomy, is thought to be a fast track to extubation and recovery after surgery. Chronic pain, due to intercostal nerve injury, develops in up to 50% of postthoracotomy patients.A number of regional anaesthesia and analgesia techniques may be employed, and the anaesthesiologists play a key role in facilitating optimal outcomes after surgery. METHODS: We report a case of postoperative pain management with a local anesthetic infiltration for MICS...

BACKGROUND: Peripheral venous cannulation is an everyday practice of care for patients undergoing anesthesia and surgery. Particles infused with intravenous fluids (eg, plastic/glass/drugs particulate) contribute to the pathogenesis of peripheral phlebitis. The aim of this study is to demonstrate the efficacy of in-line filtration in reducing the incidence of postoperative phlebitis associated with peripheral short-term vascular access. METHODS: In this controlled trial, 268 surgical patients were randomly assigned to in-line filtration and standard care (NCT03193827)...

The number and complexity of endovascular procedures performed via either arterial or venous access are steadily increasing. Albeit associated with higher morbidity compared to the radial approach, the traditional common femoral artery remains the preferred access site in a variety of cardiac, aortic, oncologic and peripheral vascular procedures. Both transarterial and venous cannulation (for electrophysiology, intravenous laser ablation and central catheterisation) at the groin may result in potentially severe vascular access site complications (VASC)...

BACKGROUND: Three types of central venous access devices (CVADs)-peripherally inserted central catheters (PICCs), skin-tunnelled central catheters (Hickman-type devices), and implantable chest wall Ports (Ports)-are routinely used in the intravenous administration of anti-cancer treatment. These devices avoid the need for peripheral cannulation and allow for home delivery of treatment. Assessments of these devices have tended to focus on medical and economic factors, but there is increased interest in the importance of patient experiences and perspectives in this area...

INTRODUCTION: Cannulation for the administration of intravenous fluids is integral to the prehospital management of injured military patients. However, this may be technically challenging to undertake during night-time conditions where the use of light to aid cannulation may give the tactical situation away to opponents. The aim of this study was to investigate the success and tactical safety of venepuncture under battlefield conditions with different colour light sources. METHOD: The procedure was carried out with naked eye in a bright room in the absence of a separate light source, with a naked eye in a dark room under red, white, blue and green light sources and under an infrared light source while wearing night vision goggles (NVGs)...

Increasing the dietary fat content of ruminant diets decreases methane (CH4 ) production. This effect is caused by the toxic properties of fatty acids on rumen microbial populations, coating of feed particles diminishing the accessibility for microbes, and a reduction in dry matter intake (DMI). The latter effect is caused by postabsorptive long-chain fatty acids eliciting anorexic signaling; however, whether circulating long-chain fatty acids affect rumen CH4 production alike is unknown. To approach this question, 5 rumen-cannulated Holstein cows in late lactation received 2 jugular catheters and were kept in respiration chambers to measure CH4 production and DMI for 48 h...
