Peritoneal blood and dialysis fluid (infused through an abdominal catheter) achieves equilibrium of most solutes generic diarex 30caps mastercard gastritis shoulder pain. Using fluids with large (glucose) molecules buy 30 caps diarex visa gastritis etiology, excess body fluid is drawn by osmosis into dialysate, then removed by negative pressure (usually gravity). Peritoneal dialysis has many limitations, including: ■ limited dialysate volumes (abdominal distension causes pain, lung splinting and impairs major organ perfusion) ■ solute removal is limited by filtrate-to-plasma concentrations (toxin levels are reduced, not eliminated) ■ loss of albumin and other large molecules (the peritoneum is highly permeable) ■ peritonitis ■ contraindications (e. Haemodialysis (and haemodiafiltration) combines diffusion, ultrafiltration and convection; toxin removal is so efficient that a few (3–5) hours treatment once or twice each week enables people with chronic renal failure to live fairly normal lives. However complications of haemofiltration include ■ cardiovascular instability ■ disequilibrium syndrome ■ immunological deficiency ■ limited water and solute removal These complications can be especially problematic with critical illness. Hypotensive episodes are twice as likely with haemodialysis as with haemofiltration (Henderson 1987). However caused, disequilibrium syndrome rarely occurs, but when it does it can be distressing for both patients and others; neurological effects include confusion, aggression, nausea/vomiting, muscle twitching, lethargy, blurred vision and possible coning. Critical illness and sedation can mask many of these symptoms, but not the discomfort problems for patients. Removing intravascular fluid encourages replacement by extravascular fluid, but limited transfer occurs during the few hours of haemodialysis, whereas continuous treatments (e. It mimics human glomerular filtration, as plasma is forced under pressure through a semipermeable Haemofiltration 347 membrane (ultrafiltration), and solutes are drawn across the membrane by convection. Unlike the human kidney, haemofiltration (and haemodialysis) cannot selectively reabsorb. Ultrafiltrate volumes are large (although smaller than healthy human ultrafiltrate), so that large infusions are needed to mimic reabsorption. Driving pressure was therefore the differential between a patient’s arterial and venous blood pressures. Anticoagulation was added to prevent thrombus formation in extracorporeal circuits; replacement fluid was given to mimic tubular reabsorption. Manufacturers are rationalising terminology by renaming ‘arterial’ circuits ‘afferent’ and ‘venous’ circuits ‘efferent’; this follows human renal physiology, and is logical, and so although not (as yet) universal, it is used here. Compared with haemodialysis, haemofiltration: ■ enables filtration despite hypotension ■ improves cardiovascular stability ■ enables more gentle removal of solutes (less disequilibrium) ■ removes significantly larger fluid volumes High-speed haemofiltration for short periods may achieve better clearance than haemodialysis, but circuits are relatively costly and time-consuming to prime, and the use of intermittent filtration is almost exclusively confined to hospitals with on-site renal units (Amoroso et al. Haemodiafiltration Ultrafiltrate countercurrent was not used with early haemofilters, so solute clearance remained poor once ultrafiltrate concentrations in filters approached plasma levels. Most units now add countercurrent to haemofiltration, calling it simply ‘haemofiltration’ (literature describing haemofiltration may not always clarify whether it refers to systems with or without countercurrents). Intensive care nursing 348 Theoretically, countercurrent clearance is proportional to countercurrent volume, but exchanges above 2–3 litres per hour do not significantly increase clearance (Miller et al. Prediluting blood (before the filter) reduces viscosity, increasing filtrate volume, urea clearance and filter life (reducing need for anticoagulation) (Kaplan 1985a); but anecdotal reports suggest predilution both hastens coagulation and reduces filter life, perhaps due to activation of clotting factors; further research is needed both to identify mechanisms and to guide practice. Free-flow ultrafiltrate relies on gravity (height difference between the filter and collection bag) to create negative pressure, but most systems now control ultrafiltrate with volumetric pumps, so that the ultrafiltrate pump speed determines negative pressure. Filter membranes Cuprophane or cellulose, used for early filters (Kwan 1997), activate the immune complement system, releasing highly vasoactive substances (e. These cause: ■ hypotensive crises ■ neutropenia Haemofiltration 349 ■ thrombocytopenia ■ hypoxia (neutrophil sequestration in pulmonary circulation). Often containing more than 20,000 fine capillary 2 tubes, they have large surface areas (often 2 m (Ervine & Milroy 1997)), a small volume and, being cylindrical, they are also sturdy. Small capillary tube diameter (65 micrometres (Ervine & Milroy 1997)) usually necessitates anticoagulation to prevent thrombosis and obstruction. Ervine and Milroy (1997) suggest hollow fibre threshold is usually about 30 kDa, but various pore-size filters are available: most of the filters now used can double this threshold. Fibres are glued with polyurethane, making them less biocompatible than flat plate filters (Molnar & Shearer 1998).
