Dialysis dehydration

The drying of ethereal solutions is an operation frequently met with. In most cases it is advisable to dry an ethereal extract before evaporating off the ether. Again, to dry a moist solid, it is often convenient to dissolve it in ether and to dry the ethereal solution with a dehydrating agent. The dry solid is then obtained by evaporation. For the drying of organic liquids by dialysis, see U. S. P., 1,885,393. 

The supportive treatment of aspirin poisoning may include gastric lavage (to prevent the further absorption of salicylate), fluid replenishment (to offset the dehydration and oliguria), alcohol and water sponging (to combat the hyperthermia), the administration of vitamin K (to prevent possible hemorrhage), sodium bicarbonate administration (to combat acidosis) and, in extreme cases, peritoneal dialysis and exchange transfusion. 

Treatment should be selected based on the grade of kidney dysfunction. In deciding on conservative therapy, hydration must be controlled. Hydration is normalized according to the presence or absence of overhydration and dehydration, although dehydration is rare. When oliguria, hyperpotassemia, and uremia are observed (21% of the patients), dialysis therapy should be considered according to the indication for dialysis therapy in acute tubular necrosis. 

In a retrospective study of 64 patients, mean age 71 years, with acute renal insufficiency associated with an ACE inhibitor, over 85% presented with overt dehydration due to diuretics or gastrointestinal fluid loss (69). Bilateral renal artery stenosis or stenosis in a solitary kidney was documented in 20% of cases. In seven patients dialysis was required, but none became dialysis dependent. After resolution of acute renal insufficiency, the plasma creatinine concentration returned to baseline and renal function was not significantly worsened. Two-year mortality was the highest in a subgroup of patients with pre-existing chronic renal insufficiency.

The transfer of intracellular K" into ECF invariably occurs in acidosis as H shifts intraceHularly and shifts outward to maintain electrical neutrality. As a general rule, K concentrations are expected to rise 0.2 to 0.7 mmol/L for every 0.1 unit drop in pH. When the underlying cause of the acidosis is treated, normokalemia will rapidly be restored. Extracellular redistribution of may also occur in (1) dehydration, (2) shock with tissue hypoxia, (3) insulin deficiency (e.g., diabetic ketoacidosis), (4) massive intravascular or extracorporeal hemolysis, (5) severe burns, (6) tumor lysis syndrome, and (7) violent muscular activity, such as that occurring in status epilepticus. Finally, important iatrogenic causes of redistribution hyperkalemia include digoxin toxicity and P adrenergic blockade, especially in patients with diabetes or on dialysis. ... 

The serum albumin of cancer patients also appears to bind less PSP than normal. This is thought (B18) to be due to the occupation of PSP-binding sites by unknown substances occurring in the blood in cancerous states, since after isolation and treatment with alcohol, but not after exhaustive dialysis, the cancer albumin recovers its PSP-binding capacity. However, the possibility that some denaturation occurred during the alcohol treatment cannot be excluded. PSP binding to an abnormal globulin of a myelomatosis serum (H26) is probably a consequence of dehydration and precipitation of the myeloma protein. 

The cornerstone of management of diarrheogenic E. coli infection is to prevent dehydration by correcting fluid and electrolyte imbalances. ORT is often lifesaving in infants and children. Treatment of EHEC infection is primarily limited to supportive care, which may include dialysis, hemoflltration, transfusion of packed erythrocytes, platelet infusions, and other interventions as indicated clinically." Severe disease may require renal transplant. Bismuth subsalicylate and loperamide are effective in decreasing the severity of ETEC diarrhea. 

HONK coma occurs mostly in elderly, non-insulin dependent diabetics, and develops relatively slowly over days or weeks. The level of insulin is sufficient to prevent ketosis but does not prevent hyperglycacmia and osmotic diuresis. Precipitating factors include severe illness, dehydration, glucocorticoids, diuretics, parenteral nutrition, dialysis and surgery. Extremely high blood glucose levels (above 35 mmol/l. and usually above 50 mmol/l) accompany severe dehydration resulting in impaired consciousness. 

Repeat-dose activated charcoal therapy effectively reduces the semm salicylate half-life, but it is not as rapidly effective as dialysis, and frequent stooling may contribute to dehydration and electrolyte disturbances. 

In patch clamp measurements with giant CFgCFj liposomes which were formed from the dialysis liposomes by dehydration/rehydration, the same type of channels (conductance states, selectivity) were observed as with the NaBr treated liposomes in dip stick bilayers (5).
