In this paper we describe the repeated replacement method (RRM), a new meshfree method for computational fluid dynamics (CFD). RRM simulates fluid flow by modeling compressible fluids' tendency to evolve towards a state of constant density, velocity, and pressure. To evolve a fluid flow simulation forward in time, RRM repeatedly "chops out" fluid from active areas and replaces it with new "flat...

OBJECTIVES To identify prognostic factors in children receiving continuous renal replacement therapy. DESIGN Historical cohort study. SETTING Neonatal and paediatric intensive care unit of a Hong Kong hospital. PATIENTS Neonatal or paediatric patients who received continuous renal replacement therapy from January 1998 to December 2008. RESULTS In all, 37 patients who received 39 episode...

BACKGROUND A conservative approach to fluid resuscitation improves survival in children with severe malaria; however, this strategy has not been formally evaluated in adults with the disease. METHODS Adults hospitalised with malaria at two tertiary referral hospitals in Myanmar received intravenous fluid replacement with isotonic saline, administered at a maintenance rate using a simple weigh...

A 60 year old woman with diuretic resistant cardiac failure was treated with intermittent haemofiltration before tricuspid valve replacement. This technique can remove large quantities of fluid rapidly, thus controlling oedema and allow appropriate fluid replacement. Haemofiltration is thus a simple and safe method of managing unresponsive oedema in cardiac failure sometimes allowing corrective...
