This switch requires profound changes in the practice of regional anaesthesia
which will probably not take place immediately. Blocks of the face appear innovating and promising, according to recent literature.”
“Of 1059 children, 35 children with various hemato-oncologic diseases were diagnosed 17-AAG with parvovirus B19 infection. The clinical spectrum included 11 immunocompromised patients presenting with prolonged pancytopenia, 7 patients with delayed hematologic recovery after stem cell transplantation, 5 patients with parvovirus B19 as possible cause of severe aplastic anemia or myelodysplastic syndrome, and 12 children with hemolytic anemia and transient aplastic crisis.”
“This work analyzes the influence of thermal Compound C degradation on the microstructure and the mechanical properties of low-density polyethylene subjected to aging at 70 degrees C in the dark for times up to 21 months. It is found that the polymer shows a gradual increase
of its elastic modulus and a dramatic reduction of its ductility, due to secondary crystallization. Infrared spectroscopy (FTIR) reveals the autoaccelerated oxidation of the polymer after 5 months aging. It is observed that the unsaturated vinylidene groups initially present in the material are gradually overridden by vinyl groups and, eventually, by t-vinylene groups. Nuclear magnetic resonance (13C NMR) shows that the initial butyl chain branches are progressively completed by shorter ramifications, namely ethyl branches. These results are discussed find more in term of macromolecular mechanisms: (i) oxidation, (ii) chain scission, and (iii) crosslinking. (c) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011″
“Purpose of review
Pediatric pulmonary arterial hypertension (PAH) continues to be a considerable problem to the pediatric
anesthesiologist, even if its management has seen remarkable advances in the recent year. It is important that anesthesiologists caring for children with PAH be aware of the increased risk, understand the pathophysiology of PAH, and form an appropriate anesthetic management plan. A review of some of the latest medical advances will provide the reader with a better understanding of the most current anesthetic management options.
The literature reviewed demonstrates sustained clinical and hemodynamic improvement in children with various types of PAH as well as increased survival in patients with idiopathic PAH using current treatment strategies. This article will provide an overview of how the current treatment and anesthetic strategies of idiopathic PAH in children have advanced over the last several years.
The first important aspect of anesthetic management is to provide adequate intraoperative anesthesia and analgesia while minimizing increases in pulmonary vascular resistance and myocardial function.
