background: replacement of the lost tissue is the major concerns of the plastic surgeons. expanded area should be coherent with the surrounding tissue. tissue expansion technique is the reforming methods the skin tissue scarcities. several methods for tissue expansion are available; including usage of silicon balloon and injecting fluid into the tissue expander. materials and methods: in a clin...

Regional citrate anticoagulation (RCA) is a valid anticoagulation method in continuous renal replacement therapies (CRRT) and different combination of citrate and CRRT solutions can affect acid-base balance. Regardless of the anticoagulation protocol, hypophosphatemia occurs frequently in CRRT. In this case report, we evaluated safety and effects on acid-base balance of a new RCA- continuous ve...

INTRODUCTION Severe bleeding after trauma frequently results in poor outcomes in children. Prehospital fluid replacement therapy is regarded as an important primary treatment option. Our study aimed, through a retrospective analysis of matched pairs, to assess the influence of prehospital fluid replacement therapy on the post-traumatic course of severely injured children. METHODS The data for...

Combining the computational fluid dynamics (CFD) and the design of experiments (DOE) methods, as a mixed approach in modeling was proposed so that to simultaneously benefit from the advantages of both modeling methods. The presented method was validated using a coal hydraulic classifier in an industrial scale. Effects of operating parameters including feed flow rate, solid content and baffle le...

Infective endocarditis is a potentially life threatening condition. It is associated with high mortality and morbidity resulting mostly due to cardiorespiratory failure. Extracorporeal membrane oxygenation is a modality of treatment used to support hypoxic respiratory failure especially in patients who are already on mechanical ventilation. Continuous renal replacement therapy is added mainly f...

Hydraulic fracturing is a phenomenon in which cracks propagate through the porous medium due to high pore fluid pressure. Hydraulic fracturing appears in different engineering disciplines either as a destructive phenomenon or as a useful technique. Modeling of this phenomenon in isothermal condition requires analysis of soil deformation, crack and pore fluid pressure interactions. In this paper...

Patients who are dying of cancer usually give up eating and then stop drinking. This raises ethical dilemmas about providing nutritional support and fluid replacement. The decision-making process should be based on a knowledge of the risks and benefits of giving or withholding treatments. There is no clear evidence that increased nutritional support or fluid therapy alters comfort, mental statu...
