Gram-negative baeteria eontain lipopolysaeeharides (endotoxins) in their outer membranes that ean remain in an active condition in products even after eell death and some ean survive moist heat sterilizatioa Although inactive by the oral route, endotoxins can induce aeute and often fatal febrile shock if they enter the bloodstream via contamirrated irrfirsion fluids, even in nanogram quantities, or via diffusion aeross membranes ftxm eontarrrinated haemodialysis solutions. 

Haemodialysis is the process of circulating the patient s blood through a machine via tubing composed of a semi-permeable material such that waste products permeate into the dialysing fluid and the blood then returns to the patient Haemodialysis solutions need not be sterile but must be flee flxm heavy bacterial contamination.

Aluminium toxicity is the likely cause of three human disorders arising from long-term haemodialysis vitamin D-resistant osteomalacia, iron adequate microcytic anaemia, and dialysis dementia (Martin, 1994). The first of these conditions is consistent with interference with calcium deposition into bone, and the accumulation of aluminium in the bone matrix. 

From 10 to 20% of an oral dose of miconazole is excreted in the urine, mainly as metabolites, within 6 days. About 50% of an oral dose may be excreted mainly unchanged in the feces. The elimination pharmacokinetics of miconazole have been described as triphasic, with a biological half-life of about 24 h. With an initial half-life of about 0.4 h, and intermediate half-life of about 2.5 h and elimination half-life of 24 h. Very little miconazole is removed by haemodialysis [3]. 

Recently, BN 52063 has been demonstrated to be effective against mastocytosis [304], a condition which was previously incurable. This suggests that PAF, as well as mast cell degranulation, may have a role in systemic mastocytosis. The injectable (pure) form of BN 52021 is much more powerful than BN 52063. Preliminary clinical investigations have shown a long and intense inhibition of ex vivo PAF-induced platelet aggregation. The injectable form is now under clinical trials in graft rejection, stroke, haemodialysis and shock.

Chronic renal failure is a common consequence of diabetes but this case is complicated by the loss of fluid and electrolytes (sodium and potassium) due to diarrhoea and vomiting. Normally, the kidneys would respond to such a challenge and maintain homeostasis but Mrs Amin s kidneys were unable to do so. Mrs Amin was put on haemodialysis and treated to control the diabetes.

Hepatitis B vaccine schedule consists of three injections given at time 0, 1 month after the first injection and a third injection given 6 months after the first injection. Patients at high risk are given a booster after 5 years to maintain the immunity profile. Patients receiving blood transfusions, haemophilia patients, patients with chronic liver disease, and haemodialysis patients are among the high-risk patients who should be vaccinated.

Finally, in countries where is it available, renal dialysis presents other challenges as many drugs are lost from the body in the course of peritoneal or haemodialysis. 

For patients who have ingested more than 30 ml of (pure) methanol or ethylene glycol, dialysis is recommended, and haemodialysis is more effective than peritoneal dialysis. Dialysis both removes the alcohols and their metabolites, and corrects the renal and metabolic disturbances and so is the preferred treatment in severe poisoning. The maintenance dose of ethanol required may be tripled during haemodialysis as ethanol is also removed. Early treatment is indicated if ethylene glycol concentrations are above 20 mg/100 ml (200 mg/1), if the arterial pH is below 7.3, if serum bicarbonate concentrations are less than 20 mM/1, and when there are oxalate crystals in the urine. 

The most effective treatment is haemodialysis, which allows the removal of salicylate and the correction of acid-base, fluid, and electrolyte disturbances, and is the preferred treatment for severe or complicated salicylate poisoning. 

The most serious complication of pericarditis is cardiac tamponade which is manifested by shortness of breath and hypotension. Emergency pericardiocentesis is required. In most cases, the frequency and duration of dialysis should be increased after pericarditis develops. Pericarditis is an absolute indication for beginning haemodialysis if the patient has not been previously dialyzed. Indomethacin may be used in patients with chest pain, although its value has not been substantiated by placebo-controlled studies. 

Hepato-renal syndrome rapid progressive (type I) with rising serum creatinine levels, or non-progressive and less severe (type II) impairment of renal function, often consequent on bacterial peritonitis, with persistent ascites responds to vasoconstrictor treatment, typically with terlipressin through constriction of splanchnic vessels and improved renal perfusion. Withdrawal of treatment does not seem to lead inevitably to recurrence. Haemodialysis may also stabilise patients. 

The calcium (Ca) and magnesium (Mg) in a haemodialysis solution were analysed...

AAS is used in a number of limit tests for metallic impurities, e.g. magnesium and strontium in calcium acetate palladium in carbenicillin sodium and lead in bismuth subgallate. It is also used to assay metals in a number of other preparations zinc in zinc insulin suspension and tetracosactrin zinc injection copper and iron in ascorbic acid zinc in acetylcysteine lead in bismuthsubcarbonate silver in cisplatinum lead in oxyprenolol aluminium in albumin solution and calcium, magnesium, mercury and zinc in water used for diluting haemodialysis solutions. 

Fluorescence measurements are useful in limit tests where the trace impurity is fluorescent or can be rendered fluorescent by chemical modification. An example is the determination of aluminium in water for use in haemodialysis solutions by formation of its salt with 8-hydroxyquinolone (Fig. 7.5) followed by quantifieation of the complex using fluorescenee speetrophotometry. The excitation wavelength is set at 392 nm and the emission is measured at 518 nm. This type of fluorescent complex can be used to determine low levels of a number of metal ions.
