The Age of Aquarius!

Among the wide range of gadgets we use in PICU to help support the sick kids we have is this one. It is an "Aquarius" haemofilter produced by 'Edwards Lifesciences Services GMBH'. We use this for Continuous Venous Venous Haemofiltration (CVVH). We generally use this when the children are in acute renal failure and need excess fluid removing &/or their chemistry correcting. Occasionally we will have children who need a drug dialysing out.

In essence we draw blood out from the patient through a large intra-vascular catheter called a 'vascath' by means of the "blood pump" which is the red roller pump [top left]. The patient's blood is pre-diluted with a dialysis solution [Multi-Bic] drawn from a reservoir bag slung beneath the machine by the green pumps before entering the blood filter in the centre of the picture. Excess water is drawn out from the filter by the yellow pump into a waste bag also underneath the machine (not shown). The filter will also correct the patient's blood chemistry and pull out any other waste products too.

Depending on the size of the patient (and they can be infants all the way up to teenagers!) we will select the appropriate size filter and the various parameters for an effective treatment. This is programmed into the computer screen at the top of this picture.

Renal Replacement Therapies is one of my 'specialities'.
